For wooden hammers, place your hammer in a vice grip with the handle facing up. Drill a small hole and place a metal bolt inside and glue it the magnet with glue or silicone. Once your glue is dry, you will have a homemade magnetic hammer that will be perfect for reaching safely into your belt bag and removing nails.
