I have plenty of cuts and scrapes from where the chipper took the branches and spit them out at me, but the biggest injury I have, a big blood-blister on my thumb, is from jamming my thumb into a door latch striker plate as I was trying to take my sweaty shirt off after using the wood chipper.

The chipper gummed up and stopped working. I bet my neighbors are happy about that. Chippers are loud.
