SRM 251MB-GT2 Folding Knife – G10 handle and N690 steel

SRM 251M Folding Knife – a compact EDC knife made of N690 steel

The SRM 251M is a compact folding knife designed for everyday carry (EDC), crafted from high-quality materials. Its minimalist design emphasizes practicality, and its light weight makes it comfortable to carry anywhere—whether in the city or out in nature.

Blade made of Austrian N690 steel

The symmetrical blade with a spear-point tip is made of Austrian Bohler N690 steel. This steel contains 17% chromium, which ensures high resistance to rust and corrosion. The added cobalt (Co) creates a uniform microstructure that improves wear resistance and maintains the sharpness of the cutting edge.

The blade is cryogenically treated by SRM to achieve a hardness of 58–60 HRC. The cooling sharpening process ensures that the blade retains its hardness and properties—resulting in a sharper and more durable cutting edge. The surface is coated with a gray titanium coating that hides minor scratches and provides additional protection.

Aluminum and G10 handle

The handle is made of an aluminum alloy with G10 inserts—a composite of fiberglass and resin. The material has a ribbed texture, which prevents slipping and ensures a secure grip. G10 ranks among the most durable materials used in knife manufacturing.

Front Flipper and Ambi-Lock System

The knife features a Front Flipper mechanism—a tab located on the spine of the blade that allows it to be opened with a sliding motion of the thumb. The mechanism is almost entirely concealed within the knife's body for a cleaner profile.

The reliable Ambi-Lock system locks the blade in place and is suitable for both right- and left-handed use. The Mono-Chassis Liner design ensures durability and smooth, long-lasting operation of the locking mechanism.

Bearings and Ambi-Clip Clamp

The built-in bearings are made of hardened steel and phosphor bronze. They ensure smooth and easy opening, while keeping the blade properly centered. The Ambi-Clip allows for tool-free position adjustment—a convenient solution for everyday carry.
