I was rushing to complete a wizard's staff for my son's Halloween costume and trying to chisel out a compartment in the staff (a branch from a tree) for the electronics to trigger a flash from a strobe light.

The chisel needed sharpening, and I was tired, but I thought it was almost done.

Luckily, when the chisel slipped, the bevel side was down, and it rode along the tendon in my left wrist, so it just unzipped the skin without doing any serious damage to anything but my pride.

After we got back from the hospital, I went back down to the basement where I had been working to try to figure out how I did it, but I couldn't remember exactly what I was doing or how I managed to be pushing the chisel to wards my left wrist.

Eventually I finished the staff and it was awesome!
