                     FOR IMMEDIATE RELEASE October 22, 2004


ACME UNITED CORPORATION REPORTS 22% SALES AND MORE THAN TRIPLE EARNINGS
INCREASES FOR THE THIRD QUARTER

FAIRFIELD, CONN. - October 22, 2004 - Acme United Corporation (ASE:ACU) today
announced net income of $1,017,000 or $.26 per diluted share for the third
quarter ending September 30, 2004 compared to $302,000 or $.08 per diluted share
for the comparable period last year. Net income for the first nine months ending
September 30, 2004 was $2,484,000, or $.66 per diluted share compared to
$995,000, or $.28 per diluted share in the comparable period last year.

         Net sales for the quarter ending September 30, 2004 were $11.6 million
compared to $9.5 million in 2003, an increase of 22%. Net sales in the U.S.
increased 21% due to the launch of new products and market share gains.
International sales increased by 4%. Net sales for the first nine months ending
September 30, 2004 were $32.5 million compared to $26.9 million in 2003, an
increase of 21% (19% at constant currency).

         The Clauss acquisition in June of this year is progressing ahead of
plan. The business contributed approximately $750,000 in revenue during the
third quarter.

         Walter C. Johnsen, President and CEO, said, "Acme United had a strong
back to school season with market share gains. I am particularly pleased with
the reception of our new products including titanium sewing scissors and paper
trimmers. The revamped Westcott ruler line was well received at the recent
school, home and office product show."

         Gross margins were 47% in the third quarter of 2004 versus 33% in the
comparable period last. The gross margin for the third quarter 2003 was reduced
by approximately $200,000 due to costs associated with the closure of
manufacturing in Germany. Gross margins for the quarter without this effect
would have been 35%. For the first nine months of 2004 gross margins were 45%
compared to 37% in 2003. The improvement is mainly due to new product sales.


                                      (3)


         Income before income taxes was $1.6 million in the third quarter of
2004 compared with $565,000 in the third quarter of 2003, an increase of $1.0
million. Pretax income for the first nine months was $4.1 million in 2004
compared to $1.9 million in 2003.

         The Company's debt less cash on September 30, 2004 was $1.8 million
compared to $5.6 million on September 30, 2003. During the first nine months of
2004, the Company repurchased 46,830 shares at a cost of $236,000.

         The Company extended its debt facility until 2007 and reduced its
interest rate to LIBOR plus 1.5%, or approximately 3.75%. The $10 million
facility had unused capacity of $6.8 million at September 30, 2004 and is no
longer tied to asset availability.

         The board of directors declared a cash dividend of 2 cents per share
payable on October 29, 2004 to shareholders of record on the close of business
on October 9, 2004.

         ACME UNITED CORPORATION is a specialized supplier of cutting devices,
measuring instruments, and safety products for school, home, and office use.
