TRC is just coming up on my radar. I'm guessing by the lack of replies good, bad or otherwise that they're fairly unknown here sfrigon1. They jumped out at me from some of the pictures in member pehota's thread 'pehota hardcore' in the Great Outdoors. I won't link to it as there are what some might consider graphic images of use on critters.
It looks like there is a bladeforums dealer for TRC Knives as well, Russianknives.com and that Mr. Tricius, a Lithuanian maker,
introduced himself here back in 2012.
I just ordered an XS Splinter in N690 from a dealer in the States today. That'll be the first I've tried from this maker and my first experience with N690. Which models do you have? It looks from your post that you're happy with them.
