Thought I would post this here as well as the honing forum because I'm pretty sure that it's not a honing issue...

I have an old Sheffield quarter-hollow blade that has been giving me fits. Setting the bevel was not a problem. Honing on the lower grits yields a shaving edge, just a little 'gritty'. It feels great on the TPT. The problem seems to occur when I get to the higher grits or try to strop it with either a pasted paddle or the linen/leather, the edge simply goes away. It will not pass HHT and will only make about 1/2 of a shave before it becomes useless.I have seen this situation before in sharpening knives and was usually able to attribute it to cheap steel but this is not a cheap blade. Is it possible that this blade is just not tempered very well? I have put great edges on a lot of razors but this one has me pulling my hair out, literally

Thanks for any suggestions.
