It's the most solid folder I own, but I haven't really used it yet (two threads here detail my whining about pocket clip woes). It's more sleek than it looks in pictures and it weighs practically nothing (well, if you're used to similarly sized steel-lined Benchmade folders). The integral compression lock feels solid in all grips, but even moreso in a left-hand forward grip (saber, paintbrush or hammer) or a right-hand reverse grip. If you're a lefty and heed others' advice about dealing with red Loctite, this is the knife for you. If you're a righty and like high-tech hollow-ground S30V/Titanium folders, and aren't bitten by the C2O bug, this is the knife for you. You may have been thinking of other fine knives in this category, and they are super-fine knives, but this is the knife for you.
Update:
On Saturday, the screws came in and the knife came to life. Feels very secure in the hand and cuts open kitty litter bags as good as Delica and 921 Switchback (for a larger, thicker knife, that's very sharp). Scored very high marks with EdgeTester stick and popped hairs equally as well as other NIB Spydercos I have.
