If I was working hourly, I wouldn't be able to knap at work either. But I am salary and set at a desk most of the day. I mostly mess up my floor on my lunch our or after hours. Sometimes I will take a break during the afternoon if things are dead. All I play with at work is small spall flakes making small points and as you can see by the pic, nothing special. I have a long way to go and especially working with flint. But it does feel pretty good when I manage to get a flake to peal off the way I think it should. I did take one of the points and glue it to a leather keychain fob I had. It used to have a brass golf piece attached but that fell of long ago. Like I said, this came up on another thread and thought it was interesting that I wasn't the only one chipping rock at work.
