Normal Weapons - Consists of all swords

Heavy Weapons - Consists of battle axes and other such weapons like clubs

Blunt Weapons - I think this is where clubs belong actually (apologies)

Short Weapons - Tomahawks, daggers, all the short puppies in this category

Firearms - Here is where you can purchase different pistols (Note, if you have crafted the Twin Holsters, you can use two of the same pistol)

Consumables - You can buy things like arrows, smoke bombs, rope darts, snares, bait, and so on from this listing.
