Dear Sir or Madam:

     We have acted as counsel for Acme United  Corporation  (the  "Company")  in
connection  with the  preparation  and filing with the  Securities  and Exchange
Commission of the  Amendment to Form S-8  Registration  Statement  (the "Amended
Registration  Statement")  relating  to an  additional  40,000  shares of Common
Stock,  par value $2.50 per share,  of the Company  (the  "Common  Stock") to be
offered  pursuant to the Acme United  Corporation  Non-Salaried  Director  Stock
Option Plan (the "Plan").

     We have  examined and are familiar  with (i) the Articles of  Incorporation
and the Bylaws of the Company,  (ii) the corporate  proceedings  authorizing the
issuance of 40,000  shares of Common Stock  pursuant to the Plan,  and (ii) such
other documents and instruments as we have considered necessary for the purposes
of the opinions hereinafter set forth.

     Based upon the foregoing, we are of the opinion that:

     1.   The  Company  has been duly  incorporated  and is a  validly  existing
          corporation   in  good  standing  under  the  laws  of  the  State  of
          Connecticut.

     2.   Upon  issuance and delivery of the shares of Common Stock  pursuant to
          the Plan and payment to the Company of the option price for the Common
          Stock,   such  shares  will  be  validly   issued,   fully  paid,  and
          nonassessable.

     We hereby  consent to the use of this  opinion and our names in  connection
with the Amended  Registration  Statement filed with the Securities and Exchange
Commission to register the shares of Common Stock to be offered as aforesaid.

                                           Very truly yours,

                                           /s/ Brody, Wilkinson and Ober, P.C.
