Westerners: you have to be careful with Kanna, the edges can chip. Japanese: watch as I tap out rc 65 high carbon steel with a hammer. We're also told not to rough sharpen Japanese chisels using a grinder, but I saw a video from a westerner interning at a Japanese classic timber frame company and he was like "yeah we also do what everyone tells you not to do like using grinders on chisels" I think the west has again fallen into this kind of mystique view of Japan. Like yeah, you can definitely crash HC steel but it takes more force than this.
