So I had a friend give me an old Gerber AR 3.00 that is freckled with rust on both sides of the blade as well as the pocket clip. I put some 3 in 1 oil on it, let it sit, and then took a scotchbrite sponge to it for a solid half hour with no noticeable results besides rather severely cutting my thumb. :stretcher: I was able to resharpen it and remove the rust along the edge to get it rather sharp, resulting in said thumb cut, so the knife is usable. But I have a couple of questions regarding the remaining rust. 1. I tried using something more coarse, namely the extra fine hone from my lansky kit, and just ended up scratching the crap out of the knife. :thumbsdown: Would steel wool do the same? 2. Since this is just going to be a cheapy knife used for dirty tasks I don't want to use my nicer ones on, is there any reason other than aesthetics to remove the rust so long as I keep it well lubed? 3. I also have a hand me down gerber multitool which works great and was well cared for, but the bit set for it was not and that is rusty as heck. Any Suggestions?
