D2 tool steel

D2 steel is known for its excellent wear resistance. This property stems from the optimal combination of chromium, carbon, vanadium, and manganese in its composition.

D2 knives outperform many other steels in abrasive cutting. The steel is hardened to 60–61 HRC.

G10 handle

G10 is a fiberglass-resin composite—a strong, wear-resistant, and highly flexible material. The grooved surface prevents the tool from slipping in your hand, even under challenging conditions.

Bearings and Opening Mechanism

The built-in bearings are made of high-quality hardened steel and phosphor bronze. They ensure smooth opening and proper centering of the blade.

Liner Lock – locking mechanism

The liner lock is one of the most common locking mechanisms used in folding knives. Its main component is a side spring located on the inside of the handle.

When the knife is fully open, the spring slides inward and locks the blade in place. To release it, press it to the side with your thumb—the knife can be closed with one hand without changing your grip.

Flipper – Quick One-Finger Unlock

The flipper mechanism uses a tab that protrudes from the spine of the blade. Its surface is slightly textured for better grip and easier opening with the index finger.

Fast and intuitive operation
A streamlined profile for ease of use

Frequently Asked Questions

What kind of steel is the blade of the Dulotec K257 made of?

The blade of the Dulotec K257 is made of D2 tool steel with a hardness of 60 HRC. D2 is known for its excellent wear resistance, due to the combination of chromium, carbon, vanadium, and manganese in its composition. This steel is particularly well-suited for abrasive cutting and outperforms many other types of steel in this area. The blade retains its edge for a long time and is relatively easy to maintain.

What is G10, and why is it used for knife handles?

G10 is a composite material made from fiberglass and resin. It is very strong, wear-resistant, and flexible. The grooved finish on the handle prevents it from slipping in your hand. The material ranks among the most durable available on the market, making it the preferred choice for high-quality knives for everyday use.

How does the liner lock mechanism work on the Dulotec K257?

A liner lock is a locking mechanism based on a side spring located on the inside of the handle. When the knife is fully open, the spring slides inward and locks the blade in place, preventing it from closing accidentally. To release it, simply press the spring to the side with your thumb. The knife can be closed with one hand without changing your grip—which is convenient when your other hand is occupied.

How do you open Dulotec K257, and what is the "Flipper" opening method?

The Dulotec K257 uses a Flipper opening mechanism. A tab protruding from the spine of the blade is pressed with the index finger using a sliding motion.
