Handles are objects generally used to make tools. Currently, there are only wooden handles.
First, use your axe on the wood. Skip this if you already have small wood.
Medium Wood ------> Small Wood
Then, use a hammestone on the small wood. Choose Large Handle when asked for the item you want to craft.
Small Wood ------> Large Handle
Continue using the hammerstone on the handle until you have the prefered handle.
