Ito San Master Japanese Carpenter Tapping Out a Kana Blade

This video shows Ito san, the Master Japanese Carpenter, showing Garrett Hack how to tap out a blade for a Kana, you have to do this when the flat on the back of the blade is worn out. Garrett Hack from Vermont was here in Tokyo for a few days, we were able to arrange a class/demo with Garrett showing his great skill and knowledge of woodworking, especially with hand planes. This was during one of the breaks in the class.

It is not needed. If you were familiar w/ Western blade sharpening methods you'd know there is a simple way to flatten & sharpen only the minimum area needed on the back of a blade.

@deezynar you haven't read a great explanation from Odate then if you think its not needed; it aids the sharpening process.

I've wondered how they deal with the hollow ground back getting into the blade edge after many sharpenings. I thought the Japanese blade edges were hard and brittle and would crack if bent cold. Obviously I was wrong about that. I think the hollow grind is a disadvantage for Japanese planes and chisels. It's not needed and creates more trouble than it's worth.
