We carry a diving knife, not because you'd believe we'd use it to ward off sharks and giant octopuses like in the movies. Instead, they are primarily used as self-rescue tools in the event 

of being entangled underwater by ropes, fishing nets, and aquatic plants. And it's safer to use as a probe in an unknown situation than it is to use your hands. A diving knife is usually worn 

on the lower leg with a rubber belt.

Knives, you need a balance between sharpness and retention. Many knives are polished by increasing the Angle of the cross section of the blade - this will of course reduce its sharpness, 

but it will also improve its edge retention. Just like the knives used in the field, the retention of the blade of the diving knife and the robustness brought by the large Angle are more 

important than the sharpness! This is why the blade of a diving knife feels dull compared to an everyday knife. The main design of the knife body is divided into regular straight blades, 

and the other side should be a serrated blade. Mainly to make it easier to cut through harder objects.

Knife head: The knife head has two kinds of pointed and flat head. In addition to the cutting function, the sharp diving knife also has the functions of digging and detecting. Flat head is not 

easy to break off, but also can better protect BCD.

Handle: Look at the handle, there are only two points: one is whether the knife body is integrated through the handle part, which is the most solid process. Second, the handle should have 

a non-slip design. The best grip design should also have an ergonomic design that fits all four fingers. Comfort and strength at the same time.

Knife sheath: The knife sheath design of diving knife is not easy to fall off as long as the safety buckle, and it is convenient to remove and recover with one hand operation when using. In 

addition, the binding with the knife sheath to play a fixed role is also crucial. The sheath strap should be flexible to avoid loosening when the wetsuit is compressed. The diving knife is only 

convenient to carry and take the knife when it is used with the strap.
