When I first noticed how long the video was, I thought it would be one of those "real time" jobs where most of the time is spent by the videographer adjusting the camera and futzing around off camera until I lost interest. So when at first the camera was being adjusted I almost tuned out. Luckily I stuck with it another few seconds....and watched through to the end. I like how the point just smoothly comes out of the bottle bottom in a matter of minutes.
Very interesting, very crafty. My resistance to learning knapping is at an all time low. There is a little devil that looks like BevanR on my left shoulder gigging me with a pitchfork telling me I need another hobby!
