Design
Blade
The shape of the blade part of the LDC knife is similar to a regular army bayonet knife from an AKM assault rifle ; however, the material of the blade is 25Kh17N2BSh steel, and its coating is made in the form of "black chrome." A small saw is provided on the butt, which allows sawing metal rods up to one centimeter thick [2] .
Handle
The handle of the knife is plastic, as a rule, of green (less often brown) color with large mesh corrugation [2] . At the rear of the handle is a firing device consisting of:
- a detachable barrel with two locking protrusions and a locking mechanism,
- trigger mechanism
- cocking lever
- safety lock
- trigger lever [2] .
The barrel is directed in the direction opposite to the blade [1] , its muzzle in the rear of the handle is covered with rubber shutters [2] . The entire sight is located on the crosshairs of the knife, the front sight in the form of a plastic protrusion - on the rear end of the handle. To remove the spent cartridge case from the chamber, a special bent petal with a hole is provided on the knife handle [2] .
Sheath
Plastic sheaths are equipped with an additional folding handle in order to use them as wire cutters to bite a telephone cable with a diameter of up to 5 mm or a steel wire woven into two cores with a diameter of up to 2.5 mm and under a voltage of 380 volts. The knife blade is fixed inside the sheath with a wide leaf spring [2] .
