So I'm about to take on my first restoration and I have a quick question about hand sanding. I read the wiki but it doesn't explicitly say this. When sanding, how close to the edge do you go? I don't want to destroy what little bevel there is by the time I've worked my way up to the 1k grit. Also, how long do I stay on 220? Just until all the patina is gone, or do you only use 220 if there is pitting?

Thanks for the help
