Recently my mop gave way. It broke just at the neck of the mop. Some of us might just throw it away but I didn't. I just put it there on the pail till this morning. I had got a new wooden stick from my shop. I even borrowed the spanner from my shop.
So I broke it and started digging the remains with my screwdriver.
Then I just screwed the new wooden stick into the hole of the neck.
Voila! It's new again!
