Thread: Kamisori identification

Hello, gentlemen,

Here's a kamisori I've owned for a few years. It has a peculiarity that I haven't often encountered. The steel insert has a wavy cut opposite the cutting edge. I've tried to show this detail in photos, and on the you tube link provided there's the same razor with the same markings. I'm calling on the specialists for information on this particularity and on the kenji.
