What Half Face Blades says:
SHPOS monolithic folding blade, Gen 3. Blade geometry has been optimized for cutting, not prying or digging. 

Body - Machined solid billet 6AL-4V Titanium Type 2 anodizing. The body is a true monolithic frame which eliminates the need for backspacers, stand offs or additional hardware while gaining strength and rigidity.

Blade – S45VN stainless steel (58-59 RHC) with a proprietary heat treat to bond with a nitride coating (62 RHC).

Lock Up – Tapered button lock and bushing coated with nitride finish to wear evenly with the blade. System will wear “in” with use, not wear “out”. The longer the blade is used, the tighter the lock up will get. Push button blade lock release has a break in period.

Pivot System – Dual, sealed roller bearings press fit into the frame. Pivot pin is captive to the blade and bearings eliminating all play in lock up and close. Dual bearing pivot system maximizes stability, while reducing friction in opening of blade.

Pocket Clip – Type 3 anodized aluminum pocket clip designed to be reversible on both sides of the body. Custom opposing inserts fill the gap to eliminate exposed threaded holes.

Quinn Knives' take:
I've had customers describe this as "the sharpest knife they own", and after handling it, I can see why. The SHPOS is designed for close work and handling immediate business. The retention ring ensure you won't drop it in a scrap, and Wharncliffe blade shape gives you a precision point, great for scenarios that require attention to detail. We love that you can deploy it three ways: via thumb stud, spine finger flick, or utilizing the button lock action. A very nice piece.

About S45VN Steel:
S45VN steel is a high-performance stainless steel developed by Crucible Industries, known for its excellent balance of hardness, toughness, edge retention, and corrosion resistance. It features a composition that includes 1.48% carbon, 16.0% chromium, 3.0% vanadium, 2.0% molybdenum, and 0.5% niobium, enhancing its properties over its predecessor, S35VN. This makes S45VN ideal for premium knives and cutting tools, offering long-lasting sharpness, resistance to wear and corrosion, and sufficient toughness to withstand impact without chipping. Despite its high hardness, it is relatively easier to sharpen compared to other high-end steels, making it a favorite among knife enthusiasts and professionals.
