Improvised Light-Weight Mallet
Lukas made a simple wooden mallet from an old bedpost before we had a real carpenter's mallet. Due to its light weight it is still useful for driving small chisels, though! Making a similar one yourself is very simple, but the grain direction of the wood is not ideal for hitting stuff...
You should be able to find it in the wood workshop.
