Hello, I would suggest doing a search on the bladeforums for info concerning this knife, there is a fair amount of info out there.
From what I've read, some people feel the blade is too thick. If you're only using it for backup, and not cutting, then you should be okay, as far as price goes, a good deal of what you are paying for are very, very, very, tight tolerances in size. Parts might be accurate to something like .005 of an inch or less. I don't know the exact number, it might be on the website. IMO in a fixed blade such close tolerances don't make much of a difference. And the materials are top-notch also. So is it worth it? if you can find one second hand, almost certainly, New, probably. But be aware of what you are paying for, personally, I'd look elsewhere, you can even get a decent custom small fixed blade for that price. Look at
www.iccknives.com for some similiarly prices options, there are others out there too.
Also, I own 2 MOD tridents, and I absolutely love them, the only complaint I've ever seen about them is that some feel the handle is a bit small. They aren't tiny, maybe those folks just have big hands.
