I just read in another post about cutting paper to check a blade's sharpness.

I thought I had read somewhere that slicing paper would actually ruin a razor, but I can't recall. Any thoughts?

DISCLAIMER: I am well aware that you can't equate a sharpness test like HHT to the hallowed "shave test", but I wish there was some repeatable, objective way to be able to compare one razor's quality to another (without waiting to grow a new beard and lather up). I'm trying to compare a blade that i'm honing to a pre-honed blade, but everything i've read seems to suggest the HHT is way too subjective.
