Help please! Restoring a katana.

Hey all,

First post! I made this account specifically to ask for help with an issue that I can't seem to resolve on my own. I recently acquired a katana from a friend who hadn't used it in years. I traded him a knife I never use for it, so it's no big investment of cash for me (this is important). The sword itself is on the cheaper side of the spectrum (I believe it was one of the assemble-your-own kits from true swords or some such place) but feels well put-together, all the fittings are tight, and the steel of the blade is I believe 1095 high carbon. Below are pictures of the sword in and out of its saya.

My problem is with the rather sorry state of the blade itself. As I said, it had been laying in my friend's closet for quite a while, and as such was not cleaned or protected against rust. When he did use it, he was careless with his cuts and then simply slammed it back into its saya without a proper cleaning. The blade is marred by what appears to be both rust and water spots (?). My question is how do I best go about removing this? Polish has done nothing, nor has super-fine steel wool. I've heard sandpaper in extremely fine grits - does this work? Again, the blade is not of crucial value to me, so if it were to be damaged beyond use I would not be too bummed. It is NOT a folded steel blade! I would just like to restore it to its former lustre and cutting abilities. As of now, I have the blade oiled to prevent further damage and sitting in its saya, awaiting advice. Any thoughts, tips, or instructions would be greatly appreciated! Below are some detailed pictures of the damage.

Water damage (?) near habaki

Some sort of rust or corrosion along the curve - this is present over most of the blade

More corrosion near the kissaki - the burrs and chips are not of as big a concern as the corrosion

The worst of the rust - the blade here has no shine whatsoever.

That's pretty much it. Any help whatsoever would be extremely appreciated!

Professional polishing is about $100 and inch.

There are gentle ways of removing oxidation and lightly restoring a blade that is not damaged. Products like Flitz and other metal polishes followed up by the proper oil treatment are available.

Can the handle be removed, that's a start.

After that, polishing advice I leave up to the experts here. I know how I do it, but I am no expert.

You can get scotch-brite pads at most hardware stores. Start with the very finest and work your way to the heavier ones if it doesn't remove the rust. The rust may already be in the steel so I wouldn't work on it expecting it to shine like new.

It looks to be a very inexpensive sword. just have a little fun with it.
 
Ditto on the gray scotch brite pads, doesn't look like you have much too lose with the finish.
 
Or if you don't want to do it yourself, I'm guessing you could find a local gunsmith with a buffing machine that could take that right off for you. I wouldn't recommend this for anything that might be an antique blade of course, but for surface discoloration like you have on a cheap modern blade? Sure, no problem.
 
Hey everybody,

Thanks so much for all your helpful suggestions, I really appreciate it! I picked up some Flitz, which seemed to do wonders for the rust and the overall shine of the blade, but did next to nothing on the water spots (if that's what they are) and long patch of corrosion on the left side. Any more thoughts? I was only able to find the liquid Flitz, maybe paste would be more potent?

You need the paste....it has a much more abrasive action than the liquid.
