Exhibit 31.1

# CERTIFICATION PURSUANT
TO SECTION 302(a) 
OF THE SARBANES-OXLEY
ACT OF 2002

I, Joseph Postbinder,
certify that:

1.
          I have reviewed this quarterly report on Form 10-QSB of Defense Industries
          International, Inc.;

2.
          Based on my knowledge, this report does not contain any untrue statement of a
          material fact or omit to state a material fact necessary to make the statements
          made, in light of the circumstances under which such statements were made, not
          misleading with respect to the period covered by this report;

3.
          Based on my knowledge, the financial statements, and other financial information
          included in this report, fairly present in all material respects the financial
          condition, results of operations and cash flows of the small business issuer as
          of, and for, the periods presented in this report;

4.
          The small business issuers other certifying officers and I are responsible
          for establishing and maintaining disclosure controls and procedures (as defined
          in Exchange Act Rules 13a-15(e) and 15d- 15(e)) for the small business issuer
          and have:

(a)
          Designed such disclosure controls and procedures, or caused such disclosure
          controls and procedures to be designed under our supervision, to ensure that
          material information relating to the small business issuer, including its
          consolidated subsidiaries, is made known to us by others within those entities,
          particularly during the period in which this report is being prepared;

(b)
          [Paragraph omitted pursuant to SEC Release Nos. 33-8238 and 34-47986]

(c)
          Evaluated the effectiveness of the small business issuers disclosure
          controls and procedures and presented in this report our conclusions about the
          effectiveness of the disclosure controls and procedures, as of the end of the
          period covered by this report based on such evaluation; and

(d)
          Disclosed in this report any change in the small business issuers internal
          control over financial reporting that occurred during the small business
          issuers most recent fiscal quarter that has materially affected, or is
          reasonably likely to materially affect, the small business issuers
          internal control over financial reporting; and

5.
          The small business issuers other certifying officers and I have disclosed,
          based on our most recent evaluation of internal control over financial
          reporting, to the small business issuers auditors and the audit committee
          of the small business issuers board of directors (or persons performing
          the equivalent function):

(a)
          All significant deficiencies and material weaknesses in the design or operation
          of internal control over financial reporting which are reasonably likely to
          adversely affect the small business issuers ability to record, process,
          summarize and report financial information; and

(b) Any fraud, whether or not
          material, that involves management or other employees who have a significant
          role in the small business issuers internal control over financial
          reporting.
