     Item 1. Security and Issuer



     The name of the issuer is Grand Toys International, Inc.("Grand"), a Nevada
corporation,   which  has  its  principal   executive   offices  at  1710  Route
Transcanadienne,  Dorval,  Quebec,  Canada,  H9P 1H7. This statement  relates to
Grand's Common Stock, $0.001 par value per share ("Common Stock").

     Item 2. Identity and Background

     This Schedule 13D is being filed by Knox Security  Engineering  Corporation
("Knox"), a Connecticut  corporation,  with its principal business address at 65
High Ridge Road,  Suite 500,  Stamford,  Connecticut  06905,  and Ofer Nissim, a
resident of the State of New York with a business address at 65 High Ridge Road,
Suite 500,  Stamford,  Connecticut  06905.  Knox is in the business of high-tech
research  and  development.  Knox is wholly  owned by Ofer  Nissim and he is the
President,  Secretary and Treasurer and sole director of Knox.  Ofer Nissim is a
citizen of Israel and a  permanent  resident  of the United  States of  America.
Within the past five years, neither Knox nor Ofer Nissim has been convicted in a
criminal proceeding  (excluding traffic violations or similar  misdemeanors) nor
been subject to a judgment,  decree or final order enjoining  future  violations
or,  or  prohibiting  or  mandating  activities  subject  to,  federal  or state
securities laws or finding any violation with respect to such laws.

     Item 3. Source and Amount of Funds or Other Consideration

     On December 30, 1998, Ark Foundation LLC, a Connecticut  limited  liability
company ("Ark"),  entered into an Asset Purchase  Agreement (the "Asset Purchase
Agreement")  with  Great  American   Acquisition  Corp.,  a  Nevada  corporation
("GAAC"), predecessor in interest to Grand, pursuant to which Ark agreed to sell
certain of its assets to GAAC.  As partial  consideration  for such assets,  Ark
also  received  200,000  shares  (the  "Preferred  Shares")  of the  Series A 5%
Cumulative Convertible Redeemable Preferred Stock, par value $5.00 per share, of
Grand Toys (the "Preferred Stock").  Ark transferred all of the Preferred Shares
to Knox.  Knox has since  converted  all  200,000 of the  Preferred  Shares into
Common Stock and sold all 200,000 of these shares of Common Stock.

     Under the terms of  conversion of the  Preferred  Stock,  Knox was owed, in
cash the difference between the $5.00 par value per share of the Preferred Stock
and the price per share of the  Common  Stock to the  extent  the price was less
than $5.00.  On March 3, 2002,  Knox agreed to accept  242,213  shares of Common
Stock,  and, on June 27, 2002,  agreed to accept an additional  57,787 shares of
Common  Stock,  in  satisfaction  of cash owed under the terms of the  Preferred
Stock.

     Item 4. Purpose of Transaction

     Knox  acquired  the  300,000  common  shares as  payment  in lieu of a cash
payment  due to Knox by the terms of the  Preferred  Stock.  The  purpose of the
acquisition  of the  shares of Common  Stock  referred  to herein is solely  for
investment.  There is no intention  other than to hold the shares for investment
and/or sell the shares, as permitted by law.

             (a)-(j) None.




     Item 5. Interest in Securities of the Issuer

             (a) Knox is the  beneficial  owner of  300,000  shares  of  Grand's
                 Common   Stock,   representing   approximately  19.64%  of  the
                 outstanding  shares of  Grand's Common Stock. As the sole owner
                 of Knox, Ofer Nissim is a beneficial owner of the Knox shares.

             (b) Each of Knox and Ofer  Nissim  are deemed to share the power to
                 vote and dispose of the Knox Shares.

             (c) None.
