You'll have to start with sand paper and elbow grease first. Don't skip grits. I don't know where you'll have to start, but maybe 220 will do. Then go 320, 400, 500, 600, 800, and go as high as you can. Then you'll have to get some buffing compound, maybe from Jantz, K&G or some other supplier (maybe you can find the right stuff locally) and buff the blade. Buffing is dangerous, but it definitely puts in that nice mirror shine. But before you buff you'll have a lot of hand sanding do do. Use a sanding block for sure. If your knife is hollow ground, you'll have to make a block that fits the curve. Ask on Shop Talk for help on that.
