Was at my Dad’s house going through some stuff and came across what I first thought was his dive knife. Then I remembered his dive knife has a similar sheath except it’s blue and the knife has a chisel point and saw notches on the back.

The sheath on this has a nifty retention lock that reminds me of the clasps on my dive watches:

Nice looking blade, what model is it?

It’s a Patriot made in Oregon by Gerber in the early 90s. His blue dive knife is a Moray made around the same time. He doesn’t remember, but I’m guessing he bought them at the same time.
