Thanks, guys!
Blade steel on both is CPM154.
I'm not a huge Kydex fan myself, but I'm slowly learning to appreciate its qualities.
Interesting side note: When I made the prototype for the Worker, I shaped the (leather) sheath to match the blade - I ran it straight on the edge, and cut in a curve on the back. Trouble was, everyone I showed it to tried to put the knife in backwards! So I went back to the shape shown, and now people seem to know how to put the knife in correctly, even though the sheath shape is opposite the blade shape.
Sometimes you just gotta field test!
