Ask me about shaving naked!
If I'm going to attempt to touch up the edge myself once my strop seems ineffective (I've got some film and glass plates), do I need to tape?
I would since you are still finding your way. I’ve been there and done that, and tape that duplicates the original (to you) condition will prevent excessive wear on the spine.
You will find your way, all of us were where you are now at one point. I’ve worn a few nice razors more than they needed to be while learning to hone. Learn the rolling X stroke, because very few straight razors are straight. Your goal is to have the toe, middle, and heel spend the same amount of time on the hone when the edge isn’t straight. Even if the blade is twisted or bent. This is quite do-able, it’s just repetition and practice, wax on, wax off.
Good honing sir!
