Hey there! Thank you for the response.
I was told mineral oil would be good to wide te blade and nakago with, so ill probably start there. Could you elaborate further on the polishing aspect? I wasn't planning on getting someone to polish until I can find someone knowledgeable in person to check it out. However, the tsuka from one of my more modern wakizashi happened to fit perfectly with the blade. I even was able to use the fuchi that came on the original tsuka, at least till I get the real tsuka wrapped.
I know this isnt an amazing sword, but for 120 bucks its my first step back into collecting nihonto after a few years, so it feels good.
