These reclaimed magnets have a lot of uses. I have them on my table saw push sticks, the wrench for changing blades so I can keep these items close by hanging them on the front of the saw cabinet. I epoxy glued one onto the end of a dowel for locating dropped screws etc., since they are so strong they will pick up quite heavy articles like dropped sockets. I have several holding steel cans on the front of a steel door on my workbench for sorting spent brass cases.
Now I have another use for these.
