Art:
I've had one of his liner locks that I accidentally sold, but it went to a good home. It was very smooth and seemed to have a little better precision of action. The frame lock is significantly sturdier and has a very nice weight to it. The handle material is thick and substantial which I like. The whole thing feels like it's machined from a single piece of thick titanium.
The flipper's a nice feature, but not at all a requirement. I find myself not using it a lot or using it to open half way and then using the thumb stud. Although it's cool to learn the exact amount of force and wrist flick to have the blade just gently click into place.
It's kind of a no frills work of perfection which is how I like most everything. The S30V steel seems to perform as good as anything although Talonite seems to slice better and 420V seems to be harder and tougher - just my own limited experience.
Fortunately, I already scratched the blade so this won't ever be for sale.
