Short sword

From DwarfFortressWiki

A short sword is typically used for combat, and is made at a Metalsmith's forge. Rock short swords can also be made from obsidian at the Craftsdwarf's workshop and make a great cheap weapon.

These have the same damage as steel, so they are extremely useful for early traps. However, they require one unit of wood and one unit of obsidian in their construction, which may not be available in abundance on many maps.

The weapons are described as being clubs with a sharp stone edge affixed to the side. According to Toady One, the weapons are supposed to wear very quickly but this functionality has not yet been implemented.^{v0.27.176.38c}

They are most likely based on Aztec Macuahuitl.
