I realy cant get my head around prices like that. We have sourced hand made knife and sheath, lifetime warrenty, all made by a Cornish knifemaker for under £100. (Mods this is not an attempt to advertise) How can they justify £350 for it? I've tried one and in my opinion its c##p. Too hard to field sharpen (how many times have you seen Mr Grylls put the edge back on his knife in the field?). The grip is thin and made my hand tired quickly. I didn't hit it with any rocks! and found the 4mm blade a bit thick for feathering and fine carving.
Nice to hear a point of view from somebody who has tried one.
On cost from my point of view I can't see how they justify it either, yes I do appreciate how the metal is HT'd, but there are many other knives out there that are handmade that do not cost £350 and the materials just do not warrant the extra cost.
