This SCUBA/DEMO Damascus knife is a prototype made from white steel folded in Damascus style. It was forged by Master Knife Maker, Takeshi Saji and shaped and ground at the Kinryu Corporation in Seki, Japan per the original owner. When the Kinryu Corporation was closing down in 2016, the 25 prototypes were discovered in storage and were later sold to a buyer in Canada who then sold them on eBay during 2016 – 2017.
According to a long-time SOG employee, these prototypes were the first batch delivered to SOG in 2004. Spencer was disappointed that the Damascus pattern being straight, so he sent them back to the Kinryu Corporation.
The next batch of 25 Damascus knives were accepted and the pommels were stamped with serial numbers and autographed by Spencer Frazer. All of these SCUBA/DEMO Damascus knives were sold at the 2004 Blade Show to lucky SOG enthusiasts.
Regardless, any SOG Enthusiast would be extremely lucky to own either Damascus knife due to their unique blade shape and excellent Japanese craftsmanship that went into forging process. This prototype is truly a great looking knife and a rare piece of SOG history.
