There should be two main groups of weapons. Blunt and sharp ones.
Sharp ones would work well against unarmored hearthlings and animals. Swords and such.
Blunt ones would be more effective against armored opponents. Clubs, sledgehammers and stuff.
At least it sounds logical that blunt weapons like hammers would be more effective against people with thick armors than sharp weapons, which the armor deflects. The wounds could be a bit different too. With blunt weapons you could do stuff like break their ribs by smashing the hammer. While sharp weapons would make deep cuts, holes and such.
