A body armour plate for in a bullet proof vest which doubles as a military shield shovel

A body armour plate for in a bullet proof vest which doubles as a military shield shovel.

With a certain mechanism so a handle can be put in or on. Maybe with a thread mechanism, or a clicking mechanism. Or simply with the handle attached and a certain vest.

Extra: Double ballistic plate possibility

Cryogenic hardened steel bullet resistant, ballistic plate

Cryogenic hardened steel bullet resistant, ballistic plate

Freeze tempering, cryogenic hardening a steel ballistic plate by bringing it to around -185 degrees celcius.
-Mainly done with liquid nitrogen.

Maybe as an extra tempering method to make it even harder.
Maybe first: Normal tempering. And baking tempering for 1-2 or more hours.

A lighter and more bulletproof military shield shovel which is also made to be used as a (small) shield

I just found old military shovels which were also made to be used as a shield.
-Shield-shovels

And my idea is to make a newer version which is lighter and also more bulletproof.

Bulletproof technology

Bulletproof technology

Body armour:
Kevlar aramid fiber
 Kevlar bulletproof vests
 And kevlar sheets, inserts for extra protection
 Kevlar panels

Carbon fiber

Dyneema fiber


Steel plates


Boron carbide plates
 Up to level IV armour


So basicly: 1 the vest itself: Fibers
                   2 The bulletproof sheet: fibers or The bulletproof plate: Steel or ceramics


Special:
 Dragon skin
  With circular discs overlapping like scales, making it a partly flexible body armour.
  And the discs are made out of silicon carbide ceramic matrices and laminates

Other:
 Liquid, gell body armour

Possibly future body armour material:
 Graphene


Bulletproof glass
 Consists out of layers of glass and layers of polycarbonate.
 First a layer of glass then a layer if polycarbonate and the a later of glass again and so on
