Thanks everyone for your feedback! I should mention that this handling tip is certainly not the only way to practice. Before I discovered it, I actually made a crude looking version with a piece of paper that mimicked a razor. It was then that I discovered I could use the razor itself by inverting the handle, and feel the actual weight and position of the blade without cutting myself.

This was my best alternative because I didn't have any safety razors to practice with.

I'm glad to see that so many people are liking the video! It inspires me to keep filming more!
