NOKS is famos for knives, made fo Russai army: Katran
and .. khm... i forget model name.. ok late i'll post about NOKS more.
Now, some info from forum at
www.knife.ru:
1) Blade is not very corrosion-safe, particullary due of special matted blade surface.
2) Knife handle (is it right term?) made of steel is very clean, smooth and is not fixed in hand well.
3) Clip often scrambles clothing.
So, this knives has interesting design, but has not very good usability, and and of course this is not "fighting knives", mainly utility knives.
If you have any questions, ask me - i'l try answer.
