Repairing worn doorknob screw holes - GIF

[mwmkravchenko]

I've seen that done with bamboo skewers, as a locksmith by trade for 40 years, I use brass inserts in the door with epoxy holding them after being threaded into the door.

Fancy. I have never seen that and installed many hundreds of doors and door lock sets. Seeing and always learning something new is why I am on here in the first place!
