All this talk about taping or not taping and effects on edge geometry in addition to talk about "if you hone than much you'll wear down your razor" have me very curious. Here is my question:

Have you ever noticeably worn down a razor under "normal*" usage?

Why am I curious? Well, I don't use any one razor much, so I can't tell on my own. I don't think retouching removes much steel at all. I don't think any one person (aside from maybe a barber) will noticeably wear a razor during their lifetime (much less a user with many razors). I don't really think taping or not taping will have a significant effect on the edge geometry (aside from the initial change due to adding tape) because I can't imagine the edge being worn down all that much. I don't think a few extra laps on a hone every month matters, even if you drop down to an 8k or equivalent.

That's what I think, but I don't actually know.

* By normal usage I mean normal upkeep without damaging the edge. For example, you buy a razor new or in good condition (little wear) and shave with it every day, honing as necessary to keep the edge keen, that counts. If you ding you edge and have to hone out a dent or chip, that DOES NOT count in this poll.
