Box MK1 Expedient Hand Grenade

A simple model for a simple and silly concept/idea for a improvised/expedient type of "modular" and a low-cost hand grenade that I named Box MK1 as the main body of the grenade is made out of square tubing and is rectangular/boxy in shape hence the name. This rectangular shape is a blessing and a curse as the shape makes the grenade harder to hold and makes any potential fragmentation pattern not as even or reliable on the other hand the shape allows a relatively small grenade to hold a greater amount of explosive compound than a rounder one of similar size making this kind of a grenade potentially a decent assault or concussion grenade. A rounder shape would be better in nearly every way but if there was an abundance of square tubing and a scarcity of rounder ones then this sort of grenade might be useful plus I simply think that a square/rectangular grenades look funky.

The "modularity" comes in that the grenade could be outfitted for multiple different purposes relatively easily, standard concussion grenade does not provide enough shrapnel? Well just stick a fragmentation sleeve to it to provide it with some.

Can't throw the standard one that far? Well, configure it with a long spoon and a stick handle to give you more leverage for throwing it further (a shrapnel sleeve can also be attached if wanted)

Nead demolition/antimaterial capabilities? Just pin more grenade bodies into the stick handle version, hold them all together with metal plates, and put on it a larger spoon and you have a hefty grenade with a large amount of a given explosive compound in it which should make it effective against most demolition/antimaterial needs.
