I personally love their stuff. :thumbup:
I find the advertising occasionally hokey, but often it does prove something of value to me (when I've bothered to watch it, I skip around a lot). For example, the fact that the liner lock on my Ti-Lite can hold something like 80 lbs is good info. No, it's not a shock/impact thing, but that still shows some durability.
My 4" Zytel Ti-Lite cost me 40 bucks, and it has been an awesome knife for EDC. The only problem I had is that I opened it with the little wave-like quillon thing while I was sitting on concrete and I actually smacked the sidewalk with the tip as it unfolded.

Slightly bent the tip, but it's still disgustingly sharp (as it was out of the box). I also got my girlfriend a Super Edge for her purse (tool, not weapon), and it's been quite sharp and sturdy, especially for its size.
Anything like these Randells or whatever just seem too expensive and arty for me to bother using. All of my edged stuff is pure functionality (just my personal taste) and so their attitude towards design works well for me. I don't really know anything about stolen designs, but it's not like they're the only company in the world to borrow ideas--in this or other industries.
The triple action wouldn't be my first choice, though; it's a big-ass hunk of metal, and it seemed more showy than functional. It's cool, it's just too big and awkward for my tastes. Same with the AK-47 they make now (plus I hate knives with a gun's name). But anything high-end by them in San Mai is pretty good. I handled a Talwar and it was a sweet piece of workmanship.
I also have one of their smallswords, and it's in great shape, has great balance, and seems (for all I can tell withough disassembling the thing) quite battle-ready.
Are they the best knives in the world? No. Are they at least as good as everything else in their class (meaning production knives)? Probably. My friend's CRKT is nowhere near as sharp or tough as mine, though it's quite reliable and decent in its own right.
I'd recommend not buying a triple action without handling one. They're a little odd.
