Broken Tools are the result of consuming the last use of any limited use tool. Mallets, if used completely, will yield a Broken Wood Tool. A Stone Hoe will yield a Broken Stone Tool, and a Stone Hatchet, a Small Broken Stone Tool. Smithing Hammers, Shovels, Steel Axes, Steel Adzes, Chisels, Steel Froes, Bow Saws, Steel Mining Picks, and Steel Hoes will yield a Broken Steel Tool if its last use is consumed. A Broken Tool can be thrown in a Trash Pit or it will decay in 1 hour.
Two Broken Steel Tools can be combined to make a Clump Of Scrap Steel. A Clump Of Scrap Steel does not decay, so it is recommended to recycle Broken Steel Tools this way.
