Guys, I'm just getting my feet wet with restoration, and I have 2 questions:

1. What's the best way to remove rust?

2. What's the best way to remove a chip out of the shaving edge? I've tried going down to the Norton 220 stone and I have aggressively sharpened it at a pretty steep angle (up to about 45 degrees) to try to file the whole blade down, but no luck. Would a Nicholson high-carbon steel file work, assuming the razor is high carbon?

Thanks!
