It happened yesterday, while I was changing my hands to shave the left side of my face, I think. I can't recall how it happened. I was distracted I guess and was performing an imprudent movement with the razor handling right when I literally hacked my filly in the back of my left hand right at the knuckle of my middle finger. Luckily the tendon remained intact but I needed stitches and a tetanus shot. Bad luck but a good reminder how dangerous these things are.
