       This Amendment No. 12 to Schedule 13D is being filed on behalf of
OZ Master Fund, Ltd. and OZ Management, L.L.C. (the "Reporting Persons")
relating to shares of Common Stock, par value $0.001 per share (the
"Shares"), of Covol Technologies, Inc., a Delaware corporation (the
"Company").  Capitalized terms not otherwise defined herein have the
meanings given in the statement on Schedule 13D originally filed as of
the reporting date of November 19, 1999.  This Amendment is being filed
pursuant to Rule 13d-2 of the Securities Exchange Act of 1934 as
amended.

       Item 5 of the Schedule 13D is hereby deleted and the following is
substituted therefor:

Item 5.      Interest in Securities of the Issuer

      (a) - (b)

       As of May 10, 2000, OZ Master Fund is the record owner of Series
C Warrants exercisable for 228,572 Shares (at $5.25 per Share), Series D
Warrants exercisable for 342,858 Shares (at $6.56 per Share) and 11,262
Shares.  The Series C Warrants and the Series D Warrants are immediately
exercisable for 571,430 Shares at the exercise prices set forth in the
preceding sentence.

       OZ Master Fund, and indirectly through its advisory relationship,
OZ Management, may each be considered beneficially to own 582,692
Shares, or 2.6% of the Company's outstanding shares as of the reporting
date.  The percentage ownership of the Reporting Persons is based upon
Company's outstanding shares, after giving effect to Shares issuable
upon the exercise of the Warrants owned by the Reporting Persons.

       Each of the Reporting Persons may be deemed to share the power to
vote or direct the vote, and to dispose or to direct the disposition of,
the Shares beneficially owned by each other.  In addition, Daniel S.
Och, as managing member of OZ Management, may be deemed to beneficially
and indirectly own the Shares that OZ Management may be deemed to
indirectly and beneficially own.

       (c)  As previously reported, OZ Master Fund was the record owner
of shares of the Company's Preferred Stock convertible into Shares.
Schedule I lists two sales by OZ Master Fund of the Preferred Stock, the
second of which reflects the sale of the balance of such shares owned by
OZ Master Fund as reported in Amendment No. 11 to Schedule 13D.  The
Preferred Stock was sold in private transactions.  As a result of the
latter sale, the Reporting Persons are no longer deemed the beneficial
owners of more than 5% of the Shares.  There were no other transactions
in the Shares by the Reporting Persons since the date of the most
recently filed Schedule 13D Amendment.

        (d)  No person is known by the Reporting Persons to have the
right to receive or the power to direct the receipt of dividends from,
