Guys I purchased an old razor a couple days ago and have been honing it up. The first time i've gotten a blade to pass the HHT not that that means it's shave ready or not but i finally feel like i'm getting close. I went from 1-3-8k then did 20 laps coticule light slurry and then 10 laps plain water. My question of the day is how much will the chromium oxide improve the edge and is it needed?
