First impressions mostly and please bear in mind this is just my opinion and in no way am I posting this as fact or proof.
First, the lock up didn't instill much confidence in me as there was absolutely no grab between the tang of the knife and the lock bar until I put a moderate amount of squeeze while cutting. Reminded me a lot of the MPR from Benchmade. While it does seem solid when I did the dreaded 'spine whack' test I just prefer more grab from my frame/liner locks. Personal preference really.
Second, I don't like the open nature of the lock bar groove inside the titanium handle slabs. In my opinion it's an open invitation for foreign particles/material.
Third, I have big hands and this knife feels small and while not flimsy it just doesn't instill the level of confidence the small Sebenza did/does.
Fourth, the detent while decent seems a bit weak for a flipper. I put a bit of 10w nanotube on it for her but it's still not flipping all the way open without a wrist flick assist.
Lastly, I'm not a fan of teflon or plastic washers. I'm not saying they're bad but in a $400+ knife I expect more.
Again, this is not a dig on Hinderer knives or the Half Track it is just my impression after handling one sampling.
