So far i haven't done the back (touch wood) but i know that it is easy to do, and stays around a while. I hope that it healed well.

I also had a run in with a chisel, cant blame it on the cat though:

I like listening to music in the shop and had a habit of throwing tools up in the air and spining and flipping them with the music.Well one particular flip of a nice 1/2" Boxwood handled mortise chisel didn't come down quite as planned and stuck in my knee, just shy of the knee-cap but hit a gusher.

The doctor that sewed it up was quite impressed with how clean the cut was, and asked with what i had cut it.
Its suprising how smug you can feel about doing something so stupid.
