ACME UNITED CORPORATION REPORTS 15% DECLINE IN SECOND QUARTER EARNINGS PER SHARE


         FAIRFIELD, CONN. - July 17, 2009 - Acme United Corporation (NYSE
AMEX:ACU) today announced that net sales for the second quarter ended June 30,
2009 were $19.2 million, compared to $22.7 million in the comparable period of
2008, a decrease of 16% (13% in local currency). Net income was $1,341,000, or
$.40 per diluted share, for the quarter ended June 30, 2009, compared to
$1,730,000 or $.47 per diluted share for the comparable period last year, a
decrease of 22% in net income and 15% in diluted earnings per share.

         Net sales for the six months ended June 30, 2009 were $30.5 million,
compared to $37.0 million in the same period in 2008, a decrease of 18% (14% in
local currency). Net income for the six months ended June 30, 2009 was
$1,383,000, or $.41 per diluted share, compared to $2,482,000, or $.68 per
diluted share in the comparable period last year, a 44% decrease in net income
and 40% in diluted earnings per share. The lower net income is primarily the
result of lower sales, partially offset by savings resulting from our cost
savings plan.

         Net sales for the quarter ended June 30, 2009 in the U.S. segment
decreased 17% compared to the same period in 2008. Net sales for the six months
ended June 30, 2009 in the U.S. segment decreased 19% compared to the same
period in 2008. Net sales in Canada for the three and six months ended June 30,
2009 decreased by 12% and 17%, respectively, in U.S. dollars but declined
approximately 1% for both periods respectively, in local currency compared to
the same periods in 2008. European net sales for the three and six months ended
June 30, 2009 decreased 3% and 5%, respectively, in U.S. dollars compared to the
same periods in 2008 but increased 11% and 9% respectively, in local currency.
Sales in Europe increased (in local currency) primarily due to increased
distribution of manicure products.

                                      (1)


         Gross margins were 37.1% in the second quarter of 2009 versus 39.3% in
the comparable period last year. For the first six months of 2009, gross margins
were 37.4% compared to 40.3% in the same period in 2008. The gross margin
decline for the three and six month periods was primarily due to fixed costs
spread over lower sales, the weaker Canadian dollar which raised the cost of
products in our Canadian segment and product mix.

         Walter C. Johnsen, Chairman and CEO said, "Our sales have been impacted
by weak demand due to the economic downturn. We have reduced costs in many
areas, but continue to fund new product development. The earnings in the second
quarter reflect aggressive attention to costs. Our debt has declined due to
working capital reductions and earnings. We believe we are well positioned to
take advantage of market opportunities during the coming quarters."

         The Company's bank debt less cash on June 30, 2009 was $8.9 million
compared to $11.3 million on June 30, 2008. During the 12 month period ended
June 30, 2009, Acme purchased 208,065 shares of its common stock for
approximately $1.9 million and paid $700,000 in dividends. As of June 30, 2009,
there were 124,335 shares that may be purchased under the outstanding stock
repurchase programs.
