It is always annoying that the handle of a tool is disengaged, a hammer or a pick loses its head... Especially since this inconvenience is relatively common and can be very dangerous. But before throwing your tool to buy another, try the aqueous method. A proven solution that will help you solve your problem.
Replace the iron of your tool in its place and let soak for 24 hours in a container of water. By re-moistening, the wood will swell and block the iron again. Then take care to wipe the tool perfectly, that it does not rust.
Another solution, for the most advanced cases, or if you have a quick need for your tool: insert a piece of metal between the handle and the head of the tool in the handle like a big nail or a corner, to fill the game and call the whole thing. This method can also be combined with the previous one.Suggest a tip for this theme
