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

The SRM 251M is a folding knife designed for everyday carry. Its minimalist design combines practicality with durable materials. Lightweight and compact, it is convenient for use both in the city and in the great outdoors.

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—significantly more than the standard 13%—which ensures high resistance to rust and corrosion.

Hardness of 58–60 HRC after cryogenic treatment
Added cobalt (Co) for a uniform structure and improved edge retention
Gray titanium coating—hides minor scratches and provides additional protection against corrosion
A groove in the center of the cutting edge for easier separation of materials
2.5 mm thick for precise and clean cutting

Cryogenic Treatment and Sharpening with Cooling

All SRM blades undergo a gentle heat treatment and a special cryogenic treatment. The result is a harder, more durable, and more corrosion-resistant blade.

The sharpening process with cooling preserves the hardness and performance characteristics of the blade. The cutting edge remains sharp longer than conventionally sharpened blades.

Front Flipper Opening Mechanism

The Front Flipper is a tab that protrudes from the blade and allows it to be opened with a sliding motion of the thumb. Its surface is slightly grooved for better grip.

Ease of use
One-handed opening
Quick and smooth opening
A clean, uncluttered design without unnecessary elements

The mechanism is almost entirely concealed within the knife's body, which enhances its ergonomics. The built-in high-quality steel bearings ensure a smooth and centered opening.

Aluminum and Micarta handle

The handle is made of an aluminum alloy with Micarta inlays. Micarta is a material composed of fiberglass and epoxy resins with a distinctive layered structure.

Lightweight and moisture-resistant
Resistant to temperature changes
Provides a secure and comfortable grip

The knife has a sturdy clip for easy carrying in your pocket.

Ambi-Lock Locking System

The blade locks in place using the Ambi-Lock system, which SRM has been developing for many years. It works equally well for both right- and left-handed users. Its precision engineering ensures a smooth and reliable lock every time it is used.

Frequently Asked Questions

What kind of steel is the blade of the SRM 251M made of?

The blade is made of Austrian Bohler N690 stainless steel. This steel contains 17% chromium, which makes it more corrosion-resistant than most standard steels. The added cobalt (Co) ensures a uniform internal structure and better edge retention. After cryogenic treatment, the steel achieves a hardness of 58–60 on the HRC scale.

What is the cryogenic treatment of SRM blades?

Cryogenic treatment is a specialized manufacturing process applied by SRM to all of its blades. It follows a gentle heat treatment and is designed to improve edge retention. The result is a harder, more durable, and corrosion-resistant blade. The cryogenic sharpening process further preserves the cutting edge’s performance characteristics.

How does the SRM 251M open?

The knife uses a Front Flipper mechanism. This is a tab that protrudes from the spine of the blade and is activated by a sliding motion of the thumb. The surface of the tab is slightly grooved for better grip. The mechanism is almost entirely hidden within the knife’s body, which preserves its sleek profile. The built-in high-quality steel bearings ensure smooth, centered one-handed opening.

What is Ambi-Lock, and how does it work?

Ambi-Lock is a locking system that SRM has been developing for many years. It locks the blade in the open position and ensures safe operation. The system is designed to work equally well for both right- and left-handed users. Its precise construction ensures smooth and reliable locking with every use.

What is the SRM 251M handle made of?

The handle is made of an aluminum alloy with Micarta inlays. Micarta is a material made from fiberglass and epoxy resins with a distinctive layered structure. It is lightweight and resistant to moisture and temperature changes. The combination of aluminum and Micarta ensures a secure and comfortable grip during use.

What are the knife's main dimensions and weight?

The blade of the SRM 251M is 76 mm long and 2.5 mm thick. The total length of the knife when open is 178 mm. It weighs 69 grams, making it lightweight and comfortable for everyday carry. The knife also features a pocket clip for added convenience.

What is the purpose of the gray titanium coating on the blade?

The gray titanium coating serves two purposes at once. From a practical standpoint, it provides additional protection for the blade against corrosion. Visually, the coating hides minor scratches and keeps the knife looking its best even with prolonged use. The combination of N690 steel and the titanium coating makes the SRM 251M a reliable and aesthetically pleasing knife for everyday use.
