Materials and Technologies

140Cr Laminated Steel

The blade is made of laminated 140Cr steel with two additional layers of stainless steel. This construction ensures high hardness, good wear resistance, and edge retention. Its properties are comparable to those of S35VN steel.

Cryogenic Treatment and Sharpening with Cooling

All SRM cutting edges undergo cryogenic treatment after heat treatment. This increases hardness and corrosion resistance. Sharpening is performed under cooling, which preserves the material’s hardness and ensures a permanently sharp cutting edge.

Micarta handle

Micarta is made from fiberglass and epoxy resins in a layered structure. The material is lightweight and resistant to moisture and temperature fluctuations. That is why it is widely used in the manufacture of knife handles.

Ambi-Lock Locking System and Mono-Chassis Liner

The Ambi-Lock system operates reliably thanks to the Mono-Chassis Liner design. The lock is easy to operate with either hand and ensures stability during use.

Tool-Free Ambi Clip

The TFAC clip allows for quick repositioning—for right- or left-handed users—without any tools. It is especially convenient when a quick change is needed on the go.

Frequently Asked Questions

What type of steel is used for the blade of the SRM 7228B-ME2?

The blade is made of 140Cr laminated steel. It consists of a hard core surrounded by two layers of stainless steel. In terms of properties, it is comparable to S35VN—it offers high hardness of HRC 61–63 in the core, good wear resistance, and long-lasting edge retention.

What is Ambi-Lock, and who is it suitable for?

Ambi-Lock is a locking system developed by SRM for two-handed operation. It is equally comfortable for right- and left-handed users. Its reliable operation is ensured by the Mono-Chassis Liner design, which guarantees precision and smooth locking with every use.

What does "Tool-Free Ambi Clip" mean for this knife?

The Tool-Free Ambi Clip, or TFAC for short, is a belt clip that can be repositioned without tools. The user can quickly adjust it to be worn on the left or right. This is especially practical when the adjustment needs to be made quickly and without additional tools.

What is Micarta as a handle material?

Micarta is a material made up of layers of fiberglass bonded with epoxy resins. The final product is lightweight and resistant to moisture and temperature changes. Its layered structure makes it strong and comfortable to grip. It is precisely these properties that make it the preferred material for crafting knife handles.

What are the dimensions and weight of the SRM 7228B-ME2?

The blade is 87 mm long and 3.1 mm thick. The total length of the knife when open is 207 mm. It weighs 113 grams. These dimensions make it suitable for everyday carry without being too heavy.

What is cryogenic treatment, and why is it important for the blade?

Cryogenic treatment is an additional heat treatment process in which the blade is cooled to a very low temperature after standard hardening. At SRM, it is applied to all blades in conjunction with a gentle heat treatment. The result is higher hardness, better corrosion resistance, and longer-lasting sharpness during prolonged use.

What is the role of the ceramic ball bearing in the knife hinge?

The ceramic ball bearing in the hinge ensures smooth and effortless opening of the blade. Unlike conventional metal bearings, ceramic bearings are more wear-resistant and perform well under various conditions. They also contribute to the precise alignment of the blade during opening and closing.
