While cutting a small piece of drywall to make a patch, I scored one side, broke it, and went to cut through the back side. I was doing this on a nice piece of poplar ply that was going to be used as wainscoting, so I decided to cut in an upwards fashion. As I approached my left hand, I slowed to a stop to think it through. I thought that if I just ease up on the pressure to reach the small amount that I had cut in from the other edge, I would be good. Nope, even eased up, that knife went through my flesh like my wife through the latest Us weekly. 3 hours in the ER and 7 stitches later, my spring break of productive work has crawled to a stop. At least there was no tendon or nerve damage.
