This dull-hook catches onto the pocket as it’s pulled out and automatically swings the blade open.

This makes the knife extremely fast to open in an emergency and allows you to reliably defend yourself when you’re rushed by an attacker.

Despite the lightweight frame and build, this knife is incredibly strong. The aluminum handle does well to balance the knife and has cutouts to give you enhanced grip strength. We love that there’s a serrated portion on the lower half of the knife. It helps with other tactical and field uses, as well as offering robust cutting power (for self-defense too).

It’s incredibly well-designed and finely-crafted. The reverse “S” blade is as unique as it is devastating. You’ll find the downward pointing tip is versatile, powerful, and capable of tactical and defense use. It also lends to different grip techniques and styles. The cutting edge uses Spyderco’s famous two-step serrations.
They’re impeccably sharp and cut cleanly, quickly, and effortlessly. This two-step pattern increases the surface area of the cutting edge by up to 24%. It might not seem like much – but in practice it becomes an extremely efficient blade. This is all made better by the excellent quality G10 handle.
It’s made from rigid and robust epoxy-filled glass fiber that’s texture to be non-slip and easy to handle.

Your fingers won’t be at risk with accidental slips and unlocks. Overall, with a blade length of just over 4”, you’re getting what you pay for. It’s a classy and superbly capably self-defense knife that’s admittedly rather expensive – but well worth it in our opinion.
