Just received a 740 in a trade and I have to say overall I like the design. It is fairly large, but there's always the mini.
I'm really liking the blade shape and handle. The handle is very comfortable and filling, though a tad thick to EDC in my opinion (.66"). I actually really like the smooth G10. It doesn't rip apart your pants, it's not too slippery, and the handle shape allows for a pretty secure grip in my opinion. It also looks nicer in my opinion. I'm not a fan of Benchmade's textured G10 anyways.
I love high (or full) flat grind knives in general, and this one has a well executed grind, both visually appealing and functional. The edge comes out to a nice thin .017".
I'm not a fan of the liner lock. While it is secure and has no detectable play when locked, the liner is very thin and just doesn't give me a feeling of confidence. It's also VERY sticky, which does make it feel more secure, but is also just annoying. I think they should have used a thicker locking liner. Ideally, in my mind, it would have an axis lock, but that would not stay true to the original.
Fit and finish is superb, which I find is something you can count on with Benchmade.
This is sort of random, but I think the backspacer is kind of cheap looking compared to the rest of the knife. I think they should have used a different material, or steel/titanium barrel spacers. The current molded plastic spacer, complete with mold line, just doesn't fit in with the rest of this beautiful knife.
