With a hollow-ground razor, the most popular style, the blade is held flat against the strop or hone and the width of the spine holds the edge at the proper angle. This makes serious mis-sharpening less likely. It probably does help to have some knife sharpening experience though.

My method using a bench strop and diamond compound is not traditional, but I've found that as long as there's no actual damage to the edge, it always restores proper sharpness while more traditional methods with a hanging strop require sharpening on a stone every few months.

I use a oneblade now, and ignore what it costs. It’s fast, convenient, safe, and has never once cut me.
