Pjrage,

Thanks for your experiment. That's a bold move, taking one for the team, and all that.

Let me just say one thing: perhaps your razor never actaully got "dull", but you merely folded over the cutting edge on the glass bottle? The glass is smooth and hard, not abrasive, so it probably did not remove the metal, and may have only bent it over, like a rolled edge?

Perhaps then the return to sharpness was simply a result of re-straightening that cutting edge? Not so much of an abrasive re-honing going on?


Just something to think about as we review your findings.

I for one, know that my white pasted cotton strop is truly abrasive, if only very mildly so, so I will certainly say that it can be used to freshen an edge.
