Now I thought that if the blade caught on the nail this showed the bevel was set and the edge had started to slightly cut into the nail. If the blade passes smoothly over the nail the bevel is not set. I use the TNT on that bases. I just breadknifed a Taylor Eye Witness to blunt the edge so I could polish the blade.
I tried the TNT before the 1k and it just rolled over the nail. 40 circles and 25 x strokes it grabbed the nail toe to heel. 6 more x strokes then on to the rest of the stones finishing on a SG 16k. 10 on Cr Ox 50 linen 100 leather then tried a shave beautiful and smooth. Edge under a loupe was straight no chips and shiny. I've used this bevel set test on each razor I've honed and the shaves are always good if the blade grabs slightly at the 1k stage. Have I got this wrong, I don't think so as the shaves are good.
