Hi,
Very good knives, indeed! I have two: am F1/3G, one of the last of an original run of 115 made 5 years ago or so, laminated with a core of a so-called "powder" steel. Very, very good kife, extremely good edge durability. A little more difficult to resharp but entirely OK with a sandpaper on a piece of leather to maintain the convex edge geometry. Or with a diamond/ceramic stone.
The other is a S1. 1" longuer than the F1. Also a very good hunting and all porpuse knife.
Enjoy yours!
