So the small knife is obviously a poor example of embellishing a famous makers signature/title? If it’s from the end of a broken sword could the person who re-fashioned it to a knife have tried to replicate the swords original info? Anything I can learn from the hamon pattern once polished? Obviously I now know enough to never try to polish a real Nihonto myself, but this being a possible broken piece with gimei mei (forged signature....is that the way to say it?) would that be bad if I did? The hamon appears very active and I think it would look very neat once polished..even if a real sword tip would it ruin any real value with me trying to bring out those hamon lines? I know I’d never try it on a real one.
