1. Make Super Sledge not-stackable, so it can gain crafting bonuses (I somehow feel, that 'must use ammo' will be the next showstoper).
2. Give some melee weapons the same knockdown for Heavy Heanded characters as the hth weapons have:
Combat Knife/Wakizashi -4
Cattle Prod -3
Super Sledge -2
Ripper -1
Super Cattle Prod -0
