wall screws | Magnets from old harddrives | piece of wood | knives = wall mounted magentic knife block
Step 1: Behind the magic
Mortice out the back of the knife block, to 1/4" from the block face.
I hung it with 2 screws, the screw head hooks were washers till I went at them with a hacksaw. Glue in place. Tip: use a sheet of paper against the back of the block and mark where the screws need to go, then place the paper against the wall and use a level for once.
Do not put up in an earthquake prone area, keep out of the reach of children, etc etc.
