Very angular design, very eye-catching design, suits my tastes. I don't find the handle to be uncomfortable myself, but others do report discomfort. My hands are pretty much medium sized if that helps.
Great lockup. Radiused tang is a great folder innovation... somewhat self adjusting for wear, works well as Spyderco delivers it.
Really probably my favorite blade profile, the "saber ground w/ swedge", or what many call a spear point. I'd rather the main bevel were flat ground, or hollow ground w/ a big 12" or 14" wheel, but that's a tweak. Heck, I'd rather it were in S30V at Rc61 or 420V at Rc59-60, but again, that's a wish.
Handle is very thin, strong, and light for it's size, since it does not have full liners and only an inlayed/recessed liner lock on one side. This is probably it's most truly unique characteristic in the ocean of production folders. Many have requested this with full liners, and I can understand that, and I'd probably buy one, but only if it had tougher steel also (S30V).
CPM 440V on both of mine take a truly excellent edge... I can get fairly clean shaving sharp, yet still with an aggressive toothy edge, done up with fine to medium diamond stones, and that is my favorite combo. (Lansky). A fine grain structure due to CPM process and vanadium content may contribute to sharpenability.
CPM440V from Spyderco is Rc55-57, so I don't find this hard to sharpen at all w/ diamond stones (this is on soft side, I really prefer Rc60 but not with 440V which gets brittle apparently). Edge holding is good enough for me, can't say I've got objective comparison data from side-by-side testing. I oughta do that I guess.
I'd rate this knife an excellent slicer type cutting instrument. It's not a truly heavy-duty, super-hard-use folder (like a Strider say or, ack, a Farid). But it is well built for what it is.
It's a fairly good self defense folder, lacking only in the depth of the index finger "guard" area, and I'd prefer to see the liner lock recessed more than it is, in either defense or utility mode (been meaning to recess mine w/ a Dremel but just haven't yet).
Overall, I like this knife very much, and put it at the top of my production folder list for this utility and defense niche with these:
BM 710 (my fav, all around, best balanced utility/defense folder around IMHO)
AFCK 800 (good utility, good secure index finger cutout makes it good for self defense also)
Spyderco Wegner (more utility oriented)
MT LCC (stout, decent utility blade, looks cool)
