I used to tape all of mine. Then I wanted to use my swaty for touch ups and didnt want to have to worry about taping the spine just to touch it up. I have since re-honed all my blades without tape.

The one exception is a particular razor that I just couldn't get right without tape. The spine on one side was worn left and right of center but there was a small area in the center with less wear. Most likely due to my lack of experience rolling x-strokes just wouldnt do it. And that is the story of the one razor I tape.

Since I gave you so much to read and never really answered your question here goes....I only have one razor that was not honed by me and I have yet to touch it up. I suppose it wouldnt be a bad idea. Does Mike Ratliff still hang around these boards?
