This is my second Fox knife, purchased because of the exemplary fit and finish of the Fox Terzuola (with Ziricote handles). This one certainly doesn't disappoint either. Fit and finish are damn near perfect, and this is on a knife that only costs £145; I have spent far more on other knives that don't come anywhere near this level of build quality (Fallkniven springs immediately to mind).
The blade is perfectly centred, with absolutely no play in any direction - and that's straight out the box; I haven't needed to touch the pivot screw at all. Lock-up is rock solid. The slightly oversized reverse side of the pivot screw acts as an over-travel stop for the lockbar, which is a nice bit of design.
The back spacer is, to quote HH, "a nce touch", and it fulfils its role perfectly, ensuring that nothing in your pocket can impact the blade edge when the knife is closed. This is, in my humble opinion, something that too many knife manufacturers leave off their framelocks. I doubt that the blue anodizing will last very long, but that's something that only the most OCD-afflicted need to concern themselves with; I mean, it's hardly going to affect the actual use of the knife, is it?
The titanium handle slabs are really thick, and the starburst design is nicely executed. Everything is lovely and smooth, and the knife is very comfartable in use.
Blade deployment is ambidextrous, slick, easy, damn near instant, and totally thumb-driven; there's no need to flick your wrist at all. The Elmax steel is shaving sharp out the box, with perfect grinds and geometry. The jimping on the thumb ramp is too smooth to do much, to be honest, but it's of no matter as the overall shape of the open knife gives a firm grip with no worries about slippage. The blade pivots on phospor-bronze washers, which I was very glad to see. I'm not a fan of Teflon, and I feel that ball-bearing designs like KVT and IKBS are just something else that can go wrong; you can't beat the simpicity of a low-friction washer.
All in all, I'm very impressed, especially at this price, and I think that I shall be adding more Fox knives to my collection.
