To fix the problem, take out the two screws that hold the wood handle in the metal sleeve, then twist the wood as far as you can into the sleeve

The handle was pretty basic unfinished wood

My only complaint is the unfinished wood handle

The handle is a weak spot (minus 1 star) and is just unfinished wood attached with two wood screws.

Solid wood and well designed with the two wood screws to hold it in place.

The wood of the handle of the wok dries and shrinks, and the handle may get loose after a few weeks of use; mine did, others report the same thing

Take out wood handle carefully to season the metal part otherwise if you try to season the metal portion you burn the wood and loosen it.
