Hmm . . . a VERY good thread. This is something I've been researching extensively the past few weeks, since I'm looking for a fixed-blade and am considering both of these(along with a Busse)on my short list.
I'd say A-1. I like the Kraton handle, and I'll take their VG-10 over Carbon V any day. Size is comprable, but I think the A-1's modified clip-point blade is more practical. I also like the way it looks with black Teflon coating; it's considerably more attractive then the Gerber. I also think that Fallkniven's construction wil prove to be superior.
And hey, Fallkniven makes Kydex sheaths!
