I was thinking that an old barber school textbook might be an interesting piece to have as it would discuss shaving, stropping and honing techniques. My guess is that YouTube and other videos (like Lynn's) are much better teaching tools, but it would be interesting to see if there are differences in technique that have developed over the years. If anyone knows of a source for an old "text" that will have some pertinent straight razor content, I would appreciate the tip.
