China People's Liberation Army's first special saber for frogman.

China People's Liberation Army's first special saber for frogman.

The amphibious frogman unit is the fist unit of the PLA Marine Corps, and its members are even more "soldiers among soldiers" among marines. Frogman troops shoulder extremely hidden and dangerous tasks: reconnaissance of sea areas and areas behind enemy lines, and elimination of mobile launchers, air defense facilities, water conservancy projects and command posts.

There may be two kinds of frogmen in the navy: one is defensive frogmen and the other is supportive frogmen, which exists as the support force of major fleets, and its main tasks are underwater escort, demining and rescue; The second is the combat frogman, belonging to the navy special forces or the marine corps. Its tasks mainly include amphibious reconnaissance, amphibious operations, operational guidance, secret infiltration and surprise attack.

As the most mysterious special forces, the navy frogman's weapons are also mysterious. I've always heard that there are special diving knives, but I'm curious. Is underwater knife training really possible? Today, we will take a look at the special saber-05 diving knife, which belongs to the frogman army.

From the overall structure, this domestic Type 05 diving knife consists of a knife body, a scabbard and a strap. It has many functions, such as cutting, splitting, picking and hammering. It can not only be used as an underwater individual self-defense weapon to drive away or assassinate dangerous fish such as sharks.

The knife body of the knife consists of a knife body, a handle and a hand guard. The shape of the knife body largely draws lessons from the shape of Boyle knife in the United States. The knife body is narrow, thin and sharp, easy to puncture and cut, which can effectively reduce the resistance when used underwater.

The tip of the knife is slightly upturned, and the edge part is longer, which effectively prolongs the puncture ability and lifting ability. The back of this diving knife is equipped with a serrated blade, which is very sharp. It can not only be used as an underwater individual self-defense weapon to drive away or assassinate dangerous fish such as sharks, but also be used as a survival tool to cut off nets, aquatic plants and other things entangled with divers.

The handle of diving knife is made of gun modified nylon plastic, which not only has its own advantages such as light weight, high strength and corrosion resistance, but also is very suitable for underwater environment. The design of the handle is simple and smooth, which is more ergonomic. Whether it's right-handed or left-handed, it won't be awkward. Both sides of the upper part are provided with rectangular grooves, which are mainly used for locking the cutter body.

The scabbard is made of gun modified nylon plastic with elastic protruding bamboo shoots on the inside. When the blade enters the sheath, the blade is fixed in the sheath to ensure that the blade will not accidentally fall when it shakes in the sheath. When drawing a knife, press and hold the button on the front of the scabbard to pull it out. In order to fit the hand perfectly, the handle of the handle is provided with five finger grooves for the fingers to hold. The lower end of the knife handle is also provided with a cylindrical hammer made of high-hardness stainless steel, which can be used to break shells and coconuts, and can also be used as a window breaker to break glass.

The total mass of Type 05 submersible with sheath is only 365g, the total length of the blade is 275mm, the blade thickness is 5mm, and the blade mass is only 232g g. The main blade body is made of special high-strength stainless steel, and the surface of the blade body has undergone special industrial treatment, which has strong anti-rust and corrosion resistance.
