I'm a college student and recently discovered straight razor shaving. I'd like to learn to restore old razors and for the most part I think I know how I should go about doing it since I have been researching constantly, but there are a still gaps in my knowledge that i was hoping you guys could help with.

Since I don't have access to power tools (and don't really have the necessary know how) I'd like to do my restorations by hand. From what I understand all I need to restore the blade is sand paper, metal polish, and a stone to hone. Is this all?

Since I'm not so handy with power tools I'm planing on purchasing replacement scales here

Razor Scales & Pin kits

but have no idea how to remove old pins or install new ones. Any help would be greatly appropriated, I'm happy to be part of the community!
