Grey - I couldn't find the post you're referencing. I've been collecting other things (mostly firearms) for years, though, so I can appreciate that newbie excitement. I understand this is a whole different ball game, and that's why I came here looking for your opinions. Quite frankly, the saya, tsuka, and tsuba are so worn (the saya is actually split down the blade-side seam) that at the very least I would be inclined to replace those parts before I put it on display. Getting the blade polished isn't incredibly important to me - it isn't like I'm going to be using it to kill zombies - however if isn't a foolish thing to spend my money on I wouldn't mind doing it at all. Especially because I would love to see how this blade was intended to look.
Anyway, I appreciate your attempt to point me in the right direction. Hopefully I'm not embarrassing myself too much. Thank you.
