Recently acquired Yukimitsu mei Katana. Nakago is old, hard, black oxidation. This is a simple 2 figure mei. My quandry is this. It is a spectacular weapon which I am thinking is in original polish. It doesn't have that "super-duper mega shine " but it does show fantastic activity in the entire length. If it really is what I "suspect" an original 1320's Yukimitsu should I spend the huge amount of money to have the polish done? I can clearly see all the mokume w itame grain, the toranha hamon etc...
