I've now had the 765 for a few days and can add a few more comments. It is by no means an extensive overview but more a few ramblings about what I picked up in a bit of use, particularly over the weekend. Cutting tasks are the normal urban EDC type tasks - opening mail, dog food bags, clam shell packaging, etc. Cutting odd bits of thread and string, cutting used plastic water bottles and, because I could, a fair bit of food prep. South Africans eat biltong, our version of jerky, so any knife the average male "saffer" carries cuts a bit of biltong.
So to start, I like the size. A 3.25 inch blade generally gives me a handle that I can get a full four finger grip on without the blade being too intimidating to sheeple. I like frame/mono/integral locks and I like titanium. The M390 is a nice bonus but not having it (or S90) would not have been a deal breaker. The decorative spacers and the filework work on the butt of the handle are really nice and I like the jimping. It is probably more decorative than functional but it works for me.
The blade grind is fine for what I need. I would have preferred a hollow or full flat but the sabre grind is high enough for me. I would have preferred dual thumb studs but this can be fixed a lot more easily than on a Sebenza for example.
The stuff I don't like : The biggie for me is the sharp corner on the frame at the lock bar. When I handled a sample in a store (see a few posts above), I thought it was the detail on the lock bar itself but it is as a result of a slot milled into the edge on the frame.
I don't feel this sharp edge on my 761 because the corners were filed down before it left the factory so there aren't sharp bits on either the frame or lockbar. I took to mine with a sharp maker rod just to get the very sharp corner off but it probably needs more work. Extended use without gloves is going to make this an uncomfortable knife for me to use with my soft urban hands and may be the deal breaker for me after I've used the knife more and really decided if it works as a regular in my rotation. I'm not sure what the design purpose of that slot in the frame is - hopefully someone chimes in and tells me that it is an innovative design addition that makes the knife spectacular in some way - until then, I think it's a mess.
The pocket clip is less of an issue. Its milled Ti so it doesn't flex well and doesn't go over pockets with big seams. I need two hands to to clip it on anything other than really lightweight pants - so it looks pretty but isn't all that functional in my mind. I was going to take it off as I did on my 761 but someone at the factory got sloppy trying to fit it and there are machining marks under the clip - not what I would have expected on a $300 knife! So the clip is staying in place even though I probably will never use it.
As I mentioned in an earlier post, the detent on my copy is strong. Stronger than I'd like but I can live with it quite happily. Opening is best achieved with a flick of the thumb. No smooth controlled opening here unless you really practice overcoming the detent gradually. The blade, being lighter than the 761's, doesn't fall as freely - I like that as there is less chance of me cutting myself when mindlessly fidgeting with the knife (not a great habit but it's there).
There is, at the 765's price point, going to be comparison the the small Sebenza. They are similar in a lot of aspects. Interestingly the cutting edges of these two knives are only a millimetre or two different.
I prefer the four finger grip on the 765 and I'd like the overall handle egos more if it was't for that sharp corner mentioned above. Steel is "better" on the 765 depending on what you regard as "better" and I like the back spacers, jimping and sculptured Ti slabs more than the Sebenza. On the Sebenza I prefer the fluid, controlled opening, the crowned spine, the hollow grind and the pocket clip that works (although my drop point version has the clip removed).
Against the old Bradley Alias 2, the 765 is, from memory, significantly more expensive (steel type, bearings, etc) but I prefer the 765 by quite a long way both aesthetically and functionally. With a similar blade length but not much else in common, against the 490 that was my other much anticipated 2016 release from Benchmade, I take the 490 every time - similar blade length, thinner blade stock and a much more comfortable handle in my opinion ... and almost $100 cheaper.
Just for giggles, a Ti Wilkins Ritter mini Grip. If it is the Ti and M390 you are chasing building one of these may be an option - I suspect it will be close to the 765's price by the time you are done.
Overall I'm not unhappy with the 765. It will get carried and used but more because I like rotating my knives and the variety that I get to use than because it is the bestest, newest ultimate cutting tool -it is far from that.
