Here is a shot of the very first prototype (2005) of the Razel (Razor/Chisel) SS (5"). Sv30, complicated grind. Eventually this blade design was run in everything from 3" to 6". When this all began, the grind technique employed here was breaking new ground. The serration top was made to cut heavy nylon net and does it very well. The tip (lower lead) was designed to take great abuse (even on pry) without breaking. These are double grind, razor sharp chisel edges. Not a fighting knife, but a very good task blade(s). Tearing open, scrapping off gaskets, cutting ugly stuff.
This was the 4" version.
