Gents, I recently bought a NOS Solingen made 5/8 Inox from a well regarded vendor in Germany. It was honed and stropped by the owner of the place and came to me 'shave-ready'. The first few shaves I got were fairly good but the razor does still drag and pull a bit. It also does not pass the HHT test and overall, it just does not seem to be as sharp as it ought to be.
I tried to touch it up a bit by passing it over a Belgian yellow Coticule and stropping it well over a 100 times afterwards on both the coarse and fine leather side of my Thiers-Issard paddle strop. The resulting shave was not any better than I got before honing and stropping. It's not worse, but there is definitely no improvement.
In order to get it really sharp (passing the HHT test is my goal), I am really considering honing it a lot more on my Coticule. I know that such a thing can take hours or even days considering the grit of the Coticule, but that seems to be my only real option. My honig and stropping technique is good, that is one thing I am absolutely sure of.
Can anyone help me out on this? I have a Coticule and a Thiers-Issard paddle strop at my disposal.
Thanks.
