When I was a kid my Dad made a magnet charger with some electrified copper coils would this be something that could be used to achieve similar results somehow? TIA (i.imgur.com)

Depending on the coils number of windings, and the size of the tool it will magnetise it pretty well. I used to do this to screwdrivers before they came pre-magnetised. And they will stay magnetised for a very long time.

Most of the time the reason for becoming demagnetised is due to dropping the tool several (many) times.
