This video is not very informative. First, the equipment used is not well described, so you are left wondering if any rotary tool/bit combination will work for this type procedure. Worst yet is that the lighting/contrast in the video is so bad that very often the viewer cannot see what the "instructors" are drawing or carving. Ron Ehlert does a much better job explaining and showing his scrimshaw work in his American Pioneer video on making a powderhorn. In that, Ron is carving on horn using hand tools, and he isn't hawking any products.
This is a very informative video which covers sharpening of many commonly used woodworking tools and even kitchen knives. It is well presented and the video is good enough to see the little micro edges he's talking about. Better still, Leonard is not trying to sell any of the products from Lee Valley Tools. This is worth seeing and maybe even worth owning.
