Thank you Sir.

And you are 100% correct. I have seen many early Model 16 Dive knives in O-1, that look like relics from the 16th century.

I believe that one has provenance as being found in an old tackle box here in Florida!

Ron/Bill, that surely doesn't look much like stainless ... though stainless steel of the late '38-'45 time period may not have been high quality. Even the "patina" color of the blade looks more like old car-spring steel (carbon), though the handle still looks like it has some bright areas. I think only a destructive metallurgy test would tell though...

One thing that we know for sure is the quality of stainless steel was not what we know of it today!

When Bo requested sample bars of 3/4" stainless steel from Carpenter Steel Company in Reading, PA. in Oct. 1938, they granted his request with two samples: number 2 (type 420) and number 2-B (type 440). The 440 Stainless would crumble to pieces when heated and hammered, and rendered itself useless for knifemaking. The number 2 type 420 with 30% carbon and 13% chromium appeared best in all aspects of forging and grinding. That sample bar was sufficient to made 4 knives, which were all sold to friends in Orlando that December.

Fast forward to present day. When you think of a stainless steel knife blade today, the first thing that comes to mind is 440 B or C material, but that wasn't the case in the 1930's!
