                                 April 24, 2006

                                 PROXY STATEMENT

     This Proxy Statement and the accompanying Notice of Annual Meeting of
Shareholders and Proxy Card are being furnished in connection with the
solicitation of proxies by the Board of Directors of Acme United Corporation, a
Connecticut Corporation, (the "Company") to be used at the Annual Meeting of
Shareholders of the Company, to be held April 24, 2006, at 11:00 A.M., local
time, at the American Stock Exchange, 86 Trinity Place, New York, New York or at
any adjournment thereof (the "Meeting"). This Proxy Statement and the enclosed
Proxy Card are being furnished on or about March 29, 2006 to all holders of
record of the Company's Common Stock, par value $2.50 per share, (the "Common
Stock") as of the close of business on March 7, 2006. A copy of the Company's
2005 Annual Report to Shareholders, including consolidated financial statements
for the fiscal year ended December 31, 2005, accompanies this Proxy Statement.

     At the Meeting, shareholders will elect nine Directors of the Company to
serve until the next Meeting.

                    Voting Securities, Record Date and Quorum

     Record Date. The Board of Directors has fixed the close of business on
March 7, 2006, as the record date (the "Record Date") for determination of
shareholders entitled to notice of and to vote at the Meeting. As of the Record
Date, there were 3,484,833 shares of Common Stock issued and outstanding and
there were no other voting securities of the Company outstanding.

     Quorum. The presence at the Meeting, in person or by proxy, of a majority
of the outstanding shares of Common Stock entitled to vote shall constitute a
quorum for the Meeting. Each outstanding share of Common Stock entitles the
record holder thereof to one vote. Abstentions and broker non-votes are not
counted as votes cast on any matter to which they relate, but are counted in
determining the presence of a quorum.

     Election of Directors. Assuming the presence of a quorum, a plurality of
the votes cast at the Meeting is required to elect each of the nominees for
Director. Abstentions and broker non-votes will not be taken into account in
determining the outcome of the election of directors.

                    Voting Rights and Solicitation of Proxies

     Eligible shareholders of record may vote at the Meeting in person or by
means of the enclosed Proxy Card. You may specify your voting choices by marking
the appropriate boxes on the Proxy Card. The proxy solicited hereby, if properly
signed and returned to the Company and not revoked prior to or at the Meeting,
will be voted in accordance with the instructions specified thereon. If you
properly sign and return your Proxy Card, but do not specify your choices, your
shares will be voted by the proxy holders as recommended by the Board of
Directors.

                                      (1)


     The Board of Directors encourages you to complete and return the Proxy Card
even if you expect to attend the Meeting. You may revoke your proxy at any time
before it is voted at the Meeting by giving written notice of revocation to the
Secretary of the Company, by submission of a proxy bearing a later date or by
attending the Meeting in person and casting a ballot.

     The proxy holders, Gary D. Penisten and Walter C. Johnsen, will vote all
shares of Common Stock represented by Proxy Cards that are properly signed and
returned by shareholders. The Proxy Card also authorizes the proxy holders to
vote the shares represented in their sole discretion with respect to any matters
not included in this Proxy Statement that may properly be presented for
consideration at the Meeting. You must return a signed Proxy Card if you want
the proxy holders to vote your shares of Common Stock.

     The cost of soliciting proxies will be borne by the Company. Following the
mailing of proxy solicitation materials, proxies may be solicited by directors,
officers and employees of the Company and its subsidiaries personally, by
telephone or otherwise. Such persons will not receive any fees or other
compensation for such solicitation. In addition, the Company will reimburse
brokers, custodians, nominees and other persons holding shares of Common Stock
for others for their reasonable expenses in sending proxy materials to the
beneficial owners of such shares and in obtaining their proxies.

                                      (2)


                                   PROPOSAL 1:
                              ELECTION OF DIRECTORS

The By-laws provide that the Company have a Board of Directors of not less than
five or more than nine directors, with the number of directors to be fixed by
the Board from time to time. The number of directors is presently fixed at nine.
Directors serve until the next annual meeting and until their respective
successors have been elected and qualified.

The Board of Directors currently consists of eight directors. One incumbent
director, Wayne R. Moore, has determined not to stand for reelection. His term
as a director will expire at the Meeting.

Nine Directors are to be elected at the Meeting to serve for one-year terms
until the 2007 Annual Meeting of Shareholders and until their respective
successors are elected and qualified. All of the nominees except two are
currently members of our Board of Directors. The Board of Directors knows of no
reason why any nominee would be unable to serve as Director. Each nominee has
consented to being named as a nominee for director of the Company in this Proxy
Statement and to serve if elected. If any nominee should for any reason become
unable to serve, then all valid proxies will be voted for the election of a
substitute nominee designated by the Board.

The following information about the nominees for election as our Directors is
based, in part, upon information furnished by the nominees.

Board of Director Meetings and Committees

The Board of Directors had seven meetings in 2005. All Directors attended at
least 75% of the aggregate of the total number of the Board meetings and
meetings of Committees of which they were a member. Board members are expected
to attend annual meetings. All eight then-incumbent Board members attended the
Annual Meeting held in 2005. The Board of Directors has established standing
Executive, Audit, and Compensation committees, each of which is comprised solely
of independent non-employee members of the Board of Directors. The Board of
Directors does not have a standing Nominating Committee.

                                      (5)


The Board has determined that each of its current directors who are standing for
reelection and each of the two non-incumbent nominees for director is
"independent" within the meaning of the applicable listing standards of the
American Stock Exchange, with the exception of Mr. Johnsen, President and Chief
Executive Officer and Mr. Olschan, Executive Vice President and Chief Operating
Officer.

Executive Committee

The Executive Committee of the Board of Directors is composed of Mr. Penisten as
Chairman, and Mr. Dunbar. The function of the Executive Committee is to act for
the Board of Directors during the intervals between meetings of the Board. The
Executive Committee had two meetings in 2005.

Audit Committee

The Audit Committee assists the Board of Directors in overseeing (1) the audit
and integrity of our financial statements, (2) the performance of our
independent auditors, (3) the adequacy and effectiveness of our accounting,
auditing and financial reporting processes, and (4) our compliance with legal
and regulatory requirements. The duties of the Audit Committee include the
selection and appointment of our independent auditors, including evaluation of
their qualifications, performance and independence. The Board of Directors has
determined that all members of the Audit Committee are "independent" and
"financially literate" within the meaning of the applicable listing standards of
the American Stock Exchange. In addition, the Board has determined that Mr. Ward
qualifies as an "audit committee financial expert" within the meaning of
regulations adopted by the Securities and Exchange Commission and has the
financial sophistication required under the listing standards of the American
Stock Exchange.

The Committee consists of Mr. Ward, Chairman, Messrs. Holden and Moore. The
Audit Committee meets at least quarterly, and more often as needed. The
Committee met five times in 2005. The Board of Directors has adopted a written
charter for the Audit Committee, which is reviewed annually by the Audit
Committee.

Nominations for Directors

The functions of the Nominating Committee are performed by the whole Board.
Board of Director nominations are recommended for the entire Board's selection
by a majority of the Board's "independent directors," as such term is defined in
Section 121A of the American Stock Exchange's listing standards.

The Board will consider nominees for directors recommended in writing by
shareholders to the Board at least sixty (60) days prior to the annual meeting
at which the election of directors is to be held (subject to certain
requirements set forth in the by-laws). The nomination should be sent in care of
the Secretary at the Company's principal executive office, and should include
the name, address, telephone number and resume of his or her business and
educational background along with a written statement by the shareholder as to
why such person should be considered for election to the Board of Directors.

                                      (6)


The Board follows the same evaluation procedures whether a candidate is
recommended by directors or shareholders. In identifying and evaluating nominees
for director, the Board considers whether the candidate has the highest ethical
standards and integrity and sufficient education, experience and skills
necessary to understand and wisely act upon the complex issues that arise in
managing a publicly-held company. To the extent the Board does not have enough
information to evaluate a candidate; the Board may send a questionnaire to the
candidate for completion in enough time for Board consideration.

Board Oversight Committee

On November 3, 2003, a temporary Board Oversight Committee was established to
evaluate and make recommendations to the Board regarding the structure and
composition of the Board. The specific responsibilities of the Committee
included developing a transition plan in anticipation of the retirement of older
members of the Board and making recommendations as to the size of the Board and
the experience of potential new candidates for membership on the Board. The
Committee is composed of Mr. Holden, Chairman, Mr. Dunbar and Ms. Murphy. The
Committee met once in 2004. Although the Committee did not meet in 2005, during
2005 the Committee engaged in discussions regarding these matters with other
members of the Board both individually and at meetings of the Board. As a result
of these discussions, the Board increased the size of the Board from eight to
nine directors and has nominated two non-incumbent individuals for election to
the Board at the Meeting.

Compensation Committee

The Compensation Committee of the Board of Directors assists the Board in
establishing the compensation policies for cash and equity compensation of our
executive officers. The duties of the Committee include evaluating and making
recommendations to the Board regarding the compensation and equity incentives
and awards for our executive officers and the administration of the Company's
Non-Salaried Director Stock Option Plan. The Committee consists of Mr. Holden,
Chairman, Messrs. Dunbar and Penisten, and Ms. Murphy. The Committee had two
meetings during 2005.

Compensation of Directors

Directors' Fees

In 2005, each Director who was not a salaried employee of the Company received
an annual fee of $14,000, payable quarterly plus $800 for each Board of
Directors meeting attended. The Chairman of the Board earned an additional $800
per meeting to compensate for the broader responsibility and related effort
associated with that position. Each member of a Committee of the Board received
$600 per Committee meeting. The Chairman of each Committee earned an additional
$600 per meeting to compensate for the broader responsibility and related
effort. The Chairman of the Audit Committee of the Board also received an annual
fee of $3,200, payable quarterly. Directors also receive reimbursement of travel
and other reasonable out-of-pocket expenses incurred in connection with
attendance at meetings.

On April 25, 2005, the date of the last annual meeting of shareholders, each
non-employee director re-elected to the Board of Directors received an annual
option grant, as provided under the 2005 Non-Salaried Director Stock Option
Plan, to purchase 2,500 shares of Common Stock with an exercise price of $15.15
per share. Each option was immediately exercisable for all of the shares
underlying the option.

Under the Non-Salaried Director Stock Option Plan each director upon becoming a
member of the Board of Directors receives an option to purchase 5,000 shares of
Common Stock.

Attendance at Annual Meetings

While the Company has no formal policy regarding the attendance of Board members
at annual meetings of shareholders, director attendance is deemed very important
and is strongly encouraged. All eight members of the Board attended the 2005
Annual Meeting of Shareholders.

Shareholder Communications with Directors

The Company has established a process for shareholders to send communications to
the Board of Directors. Shareholders may send communications to the Board of
Directors to the attention of the Secretary, Acme United Corporation, 60 Round
Hill Road, Fairfield, Connecticut 06824, who will forward them to all Board
members within a reasonable time after receipt. If the shareholder wishes the
communication to be sent to one or more specific Board members only, the
addressee should be the specific Board member(s), "c/o Secretary", who will then
forward the communication to such Board member(s). If one or more specific Board
members are not designated for such other communication, the communication will
be forwarded to the entire Board.

Retirement Plans

In December 1995, the Board of Directors adopted a resolution to freeze the
defined benefit pension plan resulting in no further benefit accruals after
February 1, 1996. The life annuity annual benefit at age 65 was zero for Walter
C. Johnsen, Brian S. Olschan, Paul G. Driscoll and Larry H. Buchtmann and $3,985
for James A. Benkovic. Amounts earned by others under this plan are not subject
to a deduction for estimated Social Security benefits, and do not include
benefits which would result from the transfer by a retiring employee of his
accrued profit-sharing account balance to the pension plan.

Change in Control Arrangements--Salary Continuation Plan

The company has a Salary Continuation Plan in effect covering officers of the
Company at the level of Corporate Vice President or above, under the age of 65.
This plan covers Walter C. Johnsen, Brian S. Olschan, James A. Benkovic, Larry
H. Buchtmann and Paul G. Driscoll and is designed to retain key employees and
provide for continuity of management in the event of an actual or threatened
change in control of the Company. The Plan provides that in the event of such a
change in control, each such key employee would have specific rights and receive
certain benefits if, within one year (or if such employee is also a director,
within two years) after such change in control, the employee is terminated
involuntarily, the employee's responsibility, status or compensation is reduced,
the employee is transferred to a location unreasonably distant from his/her
current location or the employee voluntarily resigns. In such circumstances, the
compensation which the employee would be entitled to receive would be a lump sum
payment equal to a specific number of months' compensation. Compensation
includes the employee's monthly salary rate being paid at the date of the change
in control times the number of months payable and the average monthly incentive
bonus payments for the prior three taxable years times the number of months
payable. Also, medical, life and other insurance that was in effect at the date
of disposition will continue into the future for the number of months
compensation is payable. Under the Plan, Messrs. Johnsen and Olschan would be
entitled to thirty-six (36) months benefits and Messrs. Benkovic, Buchtmann and
Driscoll would be entitled to twenty-four (24) months benefits.

The Company has a Severance Pay Plan covering officers of the Company employed
in the United States at the level of Corporate Vice President or above who are
under the age of 65. This Plan presently covers Messrs. Johnsen, Olschan,
Benkovic, Buchtmann and Driscoll and is designed to enable the Company to
attract and retain key employees. The Plan provides that an officer will be paid
compensation if: (i) such officer's employment is terminated by the Company
involuntarily for any reason other than gross misconduct (ii) such officer's
responsibility, status or compensation is reduced, or (iii) such officer is
transferred to a location unreasonably distant from his/her current location. In
such circumstances, the compensation which the employee would be entitled to
receive would be a lump sum payment equal to one months' compensation for each
year of service to the Company based upon the level of his/her compensation in
effect immediately preceding such termination. The Plan sets out a minimum and
maximum number of months' compensation payable to each such employee upon such
severance. Under the Plan Messrs. Johnsen and Olschan would be entitled to a
minimum of (9) months' compensation and a maximum of thirty (30) months'
compensation. Messrs. Benkovic, Buchtmann and Driscoll would be entitled to a
minimum of six (6) months' compensation and a maximum of eighteen (18) months'
compensation. This plan applies only if the Salary Continuation Plan does not
apply. Death benefits are also covered by this Plan. Under the Plan, the
beneficiaries of Messrs. Johnsen and Olschan would receive nine (9) months'
compensation and the beneficiaries of the other officers would receive six (6)
months' compensation.

Report of the Audit Committee

The Audit Committee oversees the Company's financial reporting process on behalf
of the Board of Directors. The Audit Committee has reviewed and discussed our
audited consolidated financial statements for the year ended December 31, 2005,
with management and with representatives of Ernst & Young LLP, our independent
auditors, including a discussion of the applicability and quality of accounting
principles, the reasonableness of significant judgments and the clarity of
disclosures in the financial statements.

Management has the primary responsibility for the financial statements and our
accounting, auditing and financial reporting processes. The Audit Committee is
not providing any expert or special assurance as to our financial statements.
Ernst & Young LLP is responsible for expressing an opinion on the conformity of
our financial statements with generally accepted accounting principles in the
United States. The Audit Committee is not providing any professional
certification as to Ernst & Young's work product.

The Audit Committee has discussed with representatives of Ernst & Young the
matters required to be discussed by Statement on Auditing Standards No. 61
(Communication with Audit Committees). The Audit Committee has received and
reviewed the written disclosures and letter from Ernst & Young required by
Independence Standards Board Standard No. 1 (Independence Discussions with Audit
Committees), and has discussed the independence of Ernst & Young with
representatives of the firm.

The Audit Committee discussed with the Company's independent auditors the
overall scope and plan for their respective audits. The Audit Committee met with
the independent auditors, with and without management present, to discuss the
results of their examinations, their evaluations of the Company's internal
controls, and the overall quality of the Company's financial reporting.

Based on the reviews and discussion referred to above, the Audit Committee
recommended to the Board of Directors that our audited consolidated financial
statement for the year ended December 31, 2005 be included in our Annual Report
on Form 10-K for the year ended December 31, 2005 for filing with the Securities
and Exchange Commission.

Compensation Committee Report on Executive Compensation

The Compensation Committee is committed to a strong, positive link between
business, performance and strategic goals, and compensation and benefit
programs.

Overall Executive Compensation Policy
-------------------------------------
Our compensation policy is designed to support the overall objective of
enhancing value for our shareholders by:

     -    Attracting, developing, rewarding and retaining highly qualified and
          productive individuals.

     -    Directly relating compensation to both Company and individual
          performance.

     -    Ensuring compensation levels that are externally competitive and
          internally equitable.

Following is a description of the elements of the Company's executive
compensation program and how each relates to the objectives and policy outlined
above.

Base Salary
-----------
The Committee reviews each executive officer's salary annually. In determining
appropriate salary levels, we consider level and scope of responsibility,
experience, company and individual performance, internal equity, as well as pay
practices of other companies relating to executives of similar responsibility.

By design, we strive to set executives' salaries at competitive market levels.

Annual Incentives
-----------------
Annual incentive cash award opportunities are made available to executives to
recognize and reward corporate and individual performance. The plan in effect
for 2005 provided for an incentive bonus based on the achievement of corporate
profitability goals and objectives set for each individual, based upon his/her
area of responsibility. The amount individual executives may earn under the
bonus plan is directly dependent upon the individual's position, responsibility
and ability to impact our financial success and corporate goals. The bonuses
awarded in 2005 to top management are listed in the Summary Compensation Table.

Stock Option Incentives
-----------------------
The Company's stock option compensation program is administered by the Board of
Directors, which acts upon recommendations of the Compensation Committee. The
purpose of the Company's Employee Stock Option Plan is to promote the interests
of the Company by enabling its key employees to acquire an increased proprietary
interest in the Company and thus to share in the future success of the Company's
business. Accordingly, the plan is intended as a means not only of attracting
and retaining outstanding management personnel but also of promoting a closer
identity of interests between employees and shareholders. Since the employees
eligible to receive options under the plan will be those who are in a position
to make important and direct contributions to the success of the Company, the
Board believes that the grant of options under the plan has been and will
continue to be in the best interests of the Company.

                                      (16)


The Company's Amended and Restated Employee Stock Option Plan terminated on
February 24, 2002 and options granted under that Plan continue to vest and to be
exercisable in accordance with their terms; however, no new options may be
granted under the Plan after February 24, 2002.

The Company adopted a new stock option plan, the Employee Stock Option Plan,
effective February 26, 2002 authorizing the grant of options to purchase up to a
total of 150,000 shares of Common Stock. The Plan was further amended on April
25, 2005 to authorize the grant of options to purchase a total of 300,000 shares
of Common Stock.


Rationale for CEO Compensation
------------------------------
Walter C. Johnsen was designated President and Chief Executive Officer of the
Company effective on November 30, 1995. His compensation package was designed to
encourage performance in line with the interests of our shareholders. We believe
Mr. Johnsen's total compensation was competitive in the external marketplace and
reflective of Company and individual performance.

The Compensation Committee Report on Executive Compensation shall not be deemed
incorporated by reference by any general statement incorporating by reference
this proxy statement into any filing under the Securities Act of 1933 or the
Securities Exchange Act of 1934, except to the extent that the Company
specifically incorporates this information by reference, and shall not otherwise
be deemed filed under such Acts.

Certain Transactions

There were no material transactions between the Company and any officer of the
Company, any director or nominee for election as director, any security holder
holding more than 5% of the Common Stock of the Company or any relative or
spouse of any of the foregoing persons.

Compliance with Section 16(a) of the Securities Exchange Act of 1934

Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
directors and executive officers, and persons who own more than 10% of a
registered class of the Company Common Stock (collectively referred to herein as
"Reporting Persons"), to file with the SEC and the American Stock Exchange
initial reports of ownership and reports of changes in ownership of Common Stock
and other equity securities of the Company. Reporting Persons are required by
SEC regulation to furnish the Company with copies of all Section 16(a) forms
they file. Based solely on review of copies of such forms received by the
Company or written representations from Reporting Persons, the Company believes
that, during the 2005 fiscal year, all Reporting Persons complied with all
applicable filing requirements under Section 16(a).

                                      (17)

Performance Graph

The following Performance Graph shall not be deemed incorporated by reference by
any general statement incorporating by reference this proxy statement into any
filing under the Securities Act of 1933 or the Securities Exchange Act of 1934,
except to the extent that the Company specifically incorporates this information
by reference, and shall not otherwise be deemed filed under such Acts.

The graph compares the yearly cumulative total shareholder return on the
Company's Common Stock with the yearly cumulative total return of (a) the AMEX
Market Index and (b) a peer group of companies that, like the Company, (i) are
currently listed on the American Stock Exchange, and (ii) have a market
capitalization of $45 million to $55 million.

                                      (18)


The Company does not believe it can reasonably identify a peer group of
companies on an industry or line-of-business basis for the purpose of developing
a comparative performance index. While the Company is aware that some other
publicly-traded companies market products in the Company's line-of-business,
none of these other companies provide most or all of the products offered by the
Company, and many offer other products or services as well. Moreover, some of
these other companies that engage in the Company's line-of-business do so
through divisions or subsidiaries that are not publicly-traded. Furthermore,
many of the other companies are substantially more highly capitalized than the
Company. For these reasons, any such comparison would not, in the opinion of the
Company, provide a meaningful index of comparative performance.

The comparisons in the graph below are based on historical data and are not
indicative of, or intended to forecast, the possible future performance of the
Company's Common Stock.

                              SELECTION OF AUDITORS

Audit Committee Pre-Approval of Independent Auditor Services

The Audit Committee pre-approves all audit and permissible non-audit services
provided by the independent auditors. These services may include audit services,
audit-related services, tax services and other services. The Audit Committee has
adopted policies and procedures for the pre-approval of services provided by the
independent auditors. The policies and procedures provide that management and
the independent auditors jointly submit to the Audit Committee a schedule of
audit and non-audit services for approval as part of the annual plan for each
year. In addition, the policies and procedures provide that the Audit Committee
may also pre-approve particular services not in the annual plan on a
case-by-case basis. For each proposed service, management must provide a
detailed description of the service and the projected fees and costs (or a range
of such fees and costs) for the service.

Fees to Auditors

Set forth below is a description of the fees for professional audit services
rendered by Ernst & Young LLP for the audit of our annual financial statements
and review of our interim financial statements for 2004 and 2005, and fees for
other services rendered by Ernst & Young LLP for 2004 and 2005.

Fee Category                      Fiscal 2005 Fees         Fiscal 2004 Fees
------------                 ----------------------   ----------------------
Audit Fees                                $183,000                 $186,000
Audit Related Fees                        $ 31,000                 $  5,000
Tax Fees                                  $ 28,000                 $ 35,000
All Other Fees                            $      0                 $      0
                             ----------------------   ----------------------
Total Fees                                $242,000                 $226,000

                                      (19)


Audit Related Fees.  These fees were for pension audits and financial reporting
consultation.

Tax Fees.  Tax services included tax compliance, tax advice, and tax planning.

The Audit Committee has determined that the provision of non-audit services
described above is compatible with maintaining Ernst & Young's independence.

Appointment of Auditors

The Company's Audit Committee has not yet appointed an independent auditor to
audit the financial statements of the Company for the fiscal year ending
December 31, 2006 because the Audit Committee is currently reviewing proposed
fees for audit and related work. The Audit Committee is not aware of any
disagreements between management and the Company's current auditors regarding
accounting principles and their application or otherwise.

Representatives of Ernst & Young LLP are expected to be present at the 2006
Annual Meeting with the opportunity to make a statement if they desire to do so
and are expected to be available to respond to appropriate questions. The
Company knows of no direct or material indirect financial interest in the
Company or of any connection with the Company by this accounting firm except the
professional relationship between auditor and client.
