Richard, I am a little more old fashion than most would think. I like to know how to take care of tools before I buy them, so that is the main reason I signed up for the sharpening class first.
The scheduling of your class date may have been a conflict for some folks and that could be the reason for low response but then again, I am not too sure. For those of us still in the full-time work force - AUG is normally a time of preparing for back to school for children and for pushing work related projects to closure prior to year-end, again.
