Dive Knives

The now famous skeletonized dive knife was designed by Ichiro Hattori and sold by TEKNA of Redwood City, CA, starting in the 1980s as the Tekna Ocean Edge T-2200. It had a length of 7 1/2″ and a blade length of 3 1/2″ making it an ideal “boot knife” on land. The skeletonized handle resulted in a total weight of 3.6 oz. The blade material was described as “Chromium Stainless Steel”, most likely 420j2, a very low carbon stainless that featured strong resistance to corrosion. The sheath was made of “Black Cycolac ABS”.

Hattori has long ceased producing this knife for Tekna, who until 2012 had been offering a serial numbered U.S. made version using 420.

A variant is the HA-BDI/BDA “Boy’s Dream” which had a plain edge fighter style with swedge. Attesting to its popularity as a standard boot knife an optional leather sheath was also offered.

  1. Hi,

    You missed some dive knives, Hattori’s current line of dive knives started out in the 1980’s as Dacor diving knives. I guess when Dacor went under they became Hattori. The models and sheaths are unchanged just the name.

    1. Hi Dave,
      Thank you for the info. Would you have any photos of such Dacor knives, or at least model numbers that could be traced?
      Photos can be sent to kurobune1852ATgmailDOTcom.
      Many thanks.
