I just tried to finish removing the smile on my Titan TH-70, which I started months ago but never finished due to the effort required. So I removed the smile and set the bevel on 1K diamond plate, then all the way up from 2K to 30K on my Shapton Pros, I did HHT etc. as I what I did with other razors. It was all good until the 30K. With all other carbon steel razors, 10 laps on the 30K would usually be too much. But with TH-70, nothing happened after 10 laps. Tried to shave with it, no happy at all, So did another 50 laps, improved a little bit but still not good enough. So had to finish the shave with another razor. I remember last time I got it shave ready was stropping on 0.1micron diamond. Thoughts?
