Sometimes still shots help a little bit: http://straightrazorpalace.com/advan...rolling-x.html

The only thing that matters is that the entire length of the edge touches the hone at some point during the pass, the motion that accomplishes that goal is usually the rolling X.

As for the scales, I don't know for sure and scales can be tricky to touch up so I'd hate to give much advice without more info or detail shots. But as long as the blade closes securely and doesn't hit the sides, I'd say leave them as is, they have an charm to them in their current state. Same for the blade, with the little bit of patina and signs of age, polish it if you want to but you don't have to.
