Well, I pulled out the S5 today and it was noticeably more rusty! Ah! Need to fix! Well, "fix" it, I did. This is temporary until I get back home from school and can use the mouse pad and sandpaper. All I did was use some sand paper on a stack of junk mail. Ah hah! The junk mail was good for something! Afterward, I took it to a buffing wheel on my drill with some white compound (that's the only compound I have out here). There's still a little black on the edge, but it looks a lot better and I put some oil on it to prevent further corrosion. Here's a picture:
It's not razor sharp, but very usable now. Much more usable than when it had rust covering most of the edge! Well, I guess my lesson learned is that SR101 is a little more "rust friendly" than SR77.
