How to Make a DIY Magnetic Hammer
So simple yet so brilliant: Designer Jung Soo Park found a way to improve a "run of the mill" hammer by incorporating a magnet at the end of the handle. It holds a few nails while you're working and if you drop a few on the floor, the magnet makes it easier to pick them up.
Make your own DIY version by simply gluing a dollar store magnet on the end of the handle, using "liquid nails" glue or epoxy. Works like a charm!
