Having two brothers who loved to tinker around the house, they enjoyed showing me a few tricks. I surprised my darling husband with this one: When you rub a screwdriver or other metals with a magnet you create a magnetized screwdriver, etc. Especially with little screws it was fun to show my husband how that screwdriver hung on to those screws and prevented their getting lost. It wasn't long after that I found every screwdriver, heads of hammers and other metal tools, etc. magnetized by hubby. He's gone now but I still enjoy using his magnetized tools.
Neat idea. I keep old speakers, they have a magnet on the back of them. I leave them setting on my work table with my tools resting on them. So my tools are always charged for magnetic pick up. If you set a metal dish on top of magnet you can have a handy screw catcher too.
