One-piece 440C stainless steel. Original basket-weave sheath.

Made by Gus Marsh c1980-1984, 1 of about 200 made.

email from Gus Marsh, July 6, 2007:

I was with the US Navy from 1967-1970 with UDT-13 in the Philippines and Vietnam. I made 26 of the three-piece diving knife for my SEAL and UDT buddies. 
The most visible difference between the two knives is that the three-piece knives have no name on the handle. 
From 1980-1984 I made about 200 Seawolf Diving knives and sold them at Gun Shows in California, Arizona and Nevada. 
These knives were made from 440C stainless steel and hardened to the Rockwell C scale of 57-58. 
I sold them for $150.00 each with either a leather or kydex sheath. I have not made anymore since 1984. 
In 1986 I sold the rights to the Seawolf Knife to Mike England from Oklahoma, who never paid me. Mike has since died and I have moved on.-- 
Gus Marsh

I met Gus Marsh at a California Custom Knives show circa 1985. 
He was not set up there, just visiting the show. 
I had seen a few of the knives earlier, as well as press coverage promoting them.


This knife is completely integral, mirror polished, .220" bladestock, 1.530" blade depth, integral construction. Excellent condition. Comes with a brown leather sheath with alligator skin inlay.
