Thanks, SM, I'm not a fan of EOs for ergonomic reasons, but the bone on that old Solingen is AGAIG.
 
here's a couple of Jacks

Here are the Specs...

Blade and spring are ATS-34, Rc 61-62 on the blade, spring @ Rc 48-49.

Lookin good, Brent! I like that main blade.
 
Maybe a little, but I don't get to chance to make many knives right now especially Jacks! And I'm really proud of this one :)

Rightfully so. It's very fine. At first glance, I thought it might be a venerable old piece, re-covered. I mean that as a high compliment. :thumbup:
