If this is a racquet grenade and a racquet grenade was actually an

Sounds reasonable, though I think I would prefer a thicker piece of wood
if it was meant to protect against shrapnel.


Is it about an inch thick? The MK2 "pineapple grenade" had big shrapnel
like the racquet grenade. It could inflict casualties up to 10 yards or
so. I infer that the fragments were slower and more easily stopped than
most pistol rounds.

I wish I knew where to research the paddle device!
