### FEATURES

#### 1\. Standard Mono-chassis liner

Mono-Chassis Liner ensures Ambi-Lock (Crossbar Lock) knives are stronger and work smoothly, reliably, and durably.

#### 2\. Ambi clip

The Ambi clip can be easily removed and reinstalled on the other side of the handle without the need for additional tools.

#### 3\. Laminated steel (140Cr)

By being laminated with 2 layers of other stainless steels, the blade provides comparable characteristics to S35VN steel. [The laminated steel pattern is a natural grain, not laser-etched, and features a random pattern.](https://srmknives.com/blogs/knife-knowledge/srm-laminated-140cr-steel-guide)

#### 4. Anti-loosening pivot

An anti-loosening pivot is a component designed to prevent the slippage of axis pins. It is detachable. 

#### 5\. Cooled sharpening

Cooled Sharpening ensures that the blade maintains its hardness and performance characteristics, resulting in a sharper, more durable edge.
