I was cutting a mortise, something I haven't done very often, and was cleaning up the top of the mortise to give myself lines to cut on, when the chisel slipped and moved violently in the direction I was pushing it. This would have been OK, except that I had stupidly put my left had in front of th chisel, and it made a deep gash in the end joint of my left index finger. I went back to the house immediatey and ran some water on it to see how bad the damage was. It was obvious that I would need stitches, so I called out to my wife, who brought me a towel, helped get the dogs in, and drove me to the hospital.
After waiting the required hour to get into the treatment area and for the death panel to decide I was worth treating I got eight stitches and a dressing, and was advised that it would take a week for the stitches to come out, two weeks to stop hurting and up to seven weeks to be fully healed. The doc says I cut the artery and the nerve to the finger tip, and will probably be numb on one side of my fingertip. Could be worse.
My record is intact still - I have only ever hurt myself on hand tools, never on a power tool. I got blood on the project, but only on the back.
