I've seen that video before. It inspired me to get the lathe knife. I found a guy in Ireland who started making them, because of another video we both saw. These lathe knives work really well.
Very interesting. My son got my wife and I a set of these when he was in Russia 20 years ago. Kinda glad I don't have to work in a shop like these people did. That shop would never pass OSHA standards for safety.
