@valdim is right. A reputable source told me a knifemaker can actually sue you if you change the knife at all while still trying to pass it off as an original. That’s why I always remove the kanji before I sharpen my knives. Better safe than sued.
Edit: I know not everyone has time to be as careful as I am. I’ll help lawsuit-proof the passaround knives coming my way too, as a thank you to the owners for letting me try them out.
