Wooden knobs, which are attached with a screw, can become stripped over time as the hole becomes enlarged from repeated use.
To repair a stripped wooden cabinet knob:
- Put a drop of wood glue in the screw hole.
- Break a toothpick in half and insert the pieces in the hole.
- Break off any excess so the toothpick doesn’t protrude past the knob.
- Thread the knob back on the screw.
