Yesterday, I honed 4 razors. 3 were just fine and I had no issues, but 1 near drove me to fits. I COULD NOT get the bevel set. I honed and honed until I feared getting hone wear on the spine. I put it down for a while, and then went back at it but this time put a layer of tape on the spine. Damn thing honed right up perfectly and gave me a great shave last night. So my question is, why would I be able to set the bevel so easily with one layer of tape when I couldn't without it? I don't get it. I realize the layer of tape would change the bevel angle slightly, but that's pretty slight. This was a 5/8 razor. I couldn't detect any issues with the spine or grind......

I just don't get it..
