Chuck Taylor asked:> What is the downside to having a wood chisel magnetized? 
The downside to having any tool magnetized is that they will attract and hold
chips and grindings of any ferromagnetic material. With a chisel, the risk is
then grindings from dressing the edge staying on the surface to be deposited on
or into the surface being worked, and larger chips may hang in the surface and
then damage the edge. Similar risks hold for plane irons.


Is it a major concern? Probably not in practice. Is it a concern? yup. Is it
annoying for those of us that work metal as well as cellulose/lignin composites,
meaning that there are often chips and fines of ferrous material around? Quite.

As for files, a magnetized file is essentially impossible to keep clean enough
to do fine work. The gullets will fill with near-unremovable ferromagnetic
detritus. A demag operation is needed to get the file clean.
