                       FOR IMMEDIATE RELEASE March 3, 2004


ACME UNITED CORPORATION REPORTS 13% SALES INCREASE AND STRONG EARNINGS

         FAIRFIELD, CONN. - March 3, 2004 - Acme United Corporation (ASE:ACU)
today announced net income for the year 2003 of $1.2 million or $.34 per diluted
share compared to $659,000 or $.19 per share in 2002. For the fourth quarter of
2003, net income was $227,000 or $.06 per diluted share compared to $40,000, or
$.01 per share in 2002.

         Net sales in 2003 were $35.0 million versus $30.9 million in 2002, an
increase of 13% (10% at constant currency). Net sales in the U.S. increased 16%
due to the launch of new products, market share gains and new customers.
International sales increased by 5% due to currency gains. Net sales for the
fourth quarter of 2003 were $8.1 million compared to $6.9 in the same quarter of
2002, an increase of 18% (14% at constant currency).

         Walter C. Johnsen, President and CEO, said, "I am particularly pleased
with our new product successes and market share gains. Products introduced
during the past 36 months accounted for 23% of 2003 revenues and continue to
gain momentum. We are entering 2004 with confidence."

         Gross margins were 37.6% in 2003 versus 33.8% in 2002. The improvement
is primarily due to new products and productivity
gains.

         Income before income taxes was $2.3 million in 2003 compared with
$97,000 in 2002. Excluding restructuring costs related to liquidating the UK
business, income before income taxes was $653,000 in 2002.

         Income tax expense for 2003 was $1.1 million versus a tax benefit of
$562,000 in 2002. In 2002 the Company recognized a significant one-time income
tax benefit associated with the UK liquidation.

                                      (3)


         The Company's debt less cash on December 31, 2003 was $3.5 million
compared to $4.5 million on December 31, 2002. In 2003, the Company repurchased
118,200 shares, or approximately 3% of the outstanding shares, at a cost of
$470,000.
