ACME UNITED CORPORATION REPORTS RECORD SECOND QUARTER SALES AND EARNINGS

         FAIRFIELD, CONN. - July 18, 2008 - Acme United Corporation (AMEX:ACU)
today announced that net sales for the quarter ended June 30, 2008 were $22.7
million, compared to $19.0 million in the same period in 2007, an increase of
20% (17% in local currency). Net sales for the six months ended June 30, 2008
were $37.0 million, compared to $31.2 million in the same period in 2007, an
increase of 18% (15% in local currency).

         Net income was $1,730,000 or $.47 per diluted share for the second
quarter ended June 30, 2008, compared to $1,522,000 or $.41 per diluted share
for the comparable period last year, an increase of 14% in net income and 15% in
diluted earnings per share. Net income for the six months ended June 30, 2008
was $2,482,000, or $.68 per diluted share, compared to $2,172,000, or $.59 per
diluted share in the comparable period last year, a 14% increase in net income
and 15% in diluted earnings per share.

         Net sales for the quarter ended June 30, 2008 in the U.S. segment
increased 23% as a result of market acceptance of new anti-microbial school
scissors, rulers, and math kits and iPoint pencil sharpeners. Net sales for the
six months ended June 30, 2008 in the U.S. segment increased 21%. Net sales in
Canada in the first six months of 2008 increased by 5% in U.S. dollars but
declined 6% in local currency due to soft demand in the overall office products
market. European net sales in the first six months of 2008 increased 18% in U.S.
dollars and 3% in local currency.

         Gross margins were 39.3% in the second quarter of 2008 versus 42.0% in
the comparable period last year. For the first six months of 2008, gross margins
were 40.3% compared to 42.6% in the same period in 2007. The gross margin
declines were due to increased costs of material, labor, and energy, and the
appreciation of the Chinese currency against the U.S. dollar. Also, in the
second quarter of 2008, the company gained market share in the highly
competitive back to school segment which reduced gross margins.

                                      (1)


         Walter C. Johnsen, Chairman and CEO, said "The second quarter and year
to date sales demonstrate the strength of our new products, and the values they
deliver to our customers. Acme's base of business has broadened during the past
several years, with growth in the mass market, office superstores, independent
dealers, and hardware and industrial markets. Our international sales base has
also grown. The broadening of our customer base and international sales has
offset weakness in some domestic accounts."

         The Company's bank debt less cash on June 30, 2008 was $11.3 million
compared to $9.6 million on June 30, 2007. The increase in bank debt during the
twelve month period was primarily due to an increase in borrowings for inventory
and accounts receivables for the back to school season as well as share
repurchases, partially offset by earnings. Based on anticipated cash flow, the
debt level is expected to decline during the second half of the year. During the
12 month period ended June 30, 2008, Acme purchased 67,600 shares of its common
stock for approximately $900,000 under its previously announced repurchase
program. As of June 30, 2008, there were 182,400 shares that may be purchased
under the outstanding stock repurchase programs.
