Wanted a hook to hang a dustpan in my print room.  Poked around here and didn't really find what I wanted.  Didn't want to use adhesive, didn't want the screws showing etc. so I created a hidden screw style hanger.  Note, I made this to hang a DUSTPAN, and while it's actually pretty strong, don't hang 30lbs on it and get upset when it breaks.  Uses #8 wood style or deck screws with a flat head and countersunk.

Two styles of hook, large/flat and narrow/round.
