claok, i can really understand where you are coming from, i mentioned before that if someone has a knife of a certain steel break it can really affect them...
anyways, just look at the strider in noss's Destruction test vs the green beret, not saying the greeen beret isn't a good knife, it just perfromed alot differenty than the strider.

thats what good heat treat can do...
take a brittle steel and make it a fairly tough steel.
plus, I think scrapyard (and maybe the swamp too) were always advertised as using scrap piles of steel, and we all know jerry is a pack rat. it's not like the swamp stopped using sr101, they just might as well take some steel and make the best knife they can out of it!
and thats what they're doing.

JMO though.
although I wouldn't consider this design a "hard use" knife, (it's designed to be more of an EDC right?) it will still probably be plenty tough for what it's designed for!

sometimes I use "wtf" but i think it's better to just "what are you talking about" or something most of the time.
