Club

The club is a craftable weapon available in all worlds and biomes. It is simple in preparation and can help a dwarf to fight off not very tough enemies.

Drops
The big yeti in the Snow World may drop one club when killed.

Crafting
The club may be crafted in all worlds and biomes and does not require any crafting station. It is the very first weapon to be crafted in the tech tree.

Other use
If the amount of yetis killed in the Snow World is too high, a good amount of clubs will be found in the stock. Those may be disassembled for one piece of wood each. It isn't much, but it's useful anyway.
