Sandvik 12C27 Steel

Sandvik 12C27 is a martensitic stainless steel with a composition optimized for professional knives. It provides high sharpness, edge stability, and corrosion resistance.

In this model, the steel has undergone cryogenic treatment by the manufacturer SRM, achieving an optimal hardness of 58–60 HRC.

Slip Joint Mechanism

A slip joint is a simple mechanism with a tensioned spring that keeps the blade closed. To open it, you use a tab or pin on the blade to overcome the spring tension.

The spring presses against the rear mechanism, thereby holding the blade open without locking it. Caution is required—applying pressure incorrectly can cause the blade to close unexpectedly. Many modern pocket knives with this mechanism feature a half-lock for added safety.

Most traditional folding knives use a slip joint mechanism. To close the knife: carefully fold the blade, being careful not to cut your fingers.
