I wanted to ask here if anyone has experience with Cold Steel knives. Specifically, I'm curious to know about the "Ultra-Lock" locking system on some of their folders. They seem to be discontinuing it and now using a "Triad" locking system for their folding knives. I've heard that CS had to pay a licensing fee to be able to use the "Ultra-Lock" system, but that they own the rights to the "Triad" lock. Makes good business sense. Not sure if it's true, but then I'm not really interested in that anyway. I've heard also that the Triad lock-up is supposedly stronger. What I wanted to know is if anyone's had any trouble with the "Ultra-Lock" system failing to be a strong enough lock-up for tactical or survival use...?
