There is a variant of the Mitsubishi Type 90 tank that doesn't have the additional parts on the muzzle (recoil compensating muzzle brakes???) near the tip of the barrel, which would work better when converted into a sword handle for a fist hole.

The problem is that if the hand isn't sculpted tightly enough, the sword would easily fall off during toy play when you're smacking the sword up against other weapons and bots. Couldn't they make the sword out of harder plastic? (i.e. some plastic quality as the fists themselves) -- that would solve the problem of denting on the handles.
