@IcooIey @ai6yr @ATLeagle Put the fork back in the handle, tap the other end of the handle on the ground to set the tang. If it keeps coming out, put a thin piece of wood like a popsicle stick in and repeat the process.
With a fresh handle it's a very strong joint. As the wood gets old and starts to break down, this is what happens. First sign that you will be buying a new handle.
