Modern protective vests made of kelver are most often used by police officers, solders, security guards and important persons. These vests protect very well against pistol ammunition.
Military protective vests usually have steel plates on the front and back as additional protection against shrapnel and more powerful desert ammunition. Steel plates are heavy and make the movement of soldiers much more difficult. And they only serve at the moment of combat. Most of the time they are useless. In order to increase the functionality of such bulletproof vests, the steel plates could be made of several overlapping parts. In battle, these steel elements would serve to protect the body, and in other situations, they could serve as tools for other purposes. Each part should have two small screw holes through which they can be attached to the brackets. By connecting to the holders, the steel parts could be turned into axes, shovels, hoes, pickaxes or axes. It is a tool that soldiers need when they dig in, make dugouts or cut down trees. By combining several tools, quick-folding chairs could be created for sitting in wet swampy locations. The steel parts would have to be able to be quickly placed in the front part of the vest, while the holders could be placed in the back part of the protective vest.
In this way, in times of non-combat, they would get a very useful tool from the vests, which have their function only in times of combat.
