I've wondered about the thinning of vinyl tape on spines ever since I started taping. After reading some responses, I did a search for titanium tape. Figured that would be harder than any blade and would hold up during honing. Unfortunately, the only titanium tape I could find is not adhesive backed and is used for some sort of joint pain relief. Like copper bracelets I suppose.

But, I did find S.S. adhesive tape and got to wondering. Isn't S.S. harder than razor steel (except for S.S. blades)? If this is the case, should it wear down slower than the edge during honing? Granted, it's pricey and seems to be too wide, but it is a thought. Just wondering, what do the experts think about this. Here's one of the links I found.
