I rehoned my black frontier razor. It has become my test razor for now. Razor had a shaving edge but since I sealed a new asagi that needed testing I decided to try just tomo slurry. First try was with the small tomo on the right, edge was worse than before. Tried one more dilution but still tugging. Decided to try to raise slurry from the stone on the right that I am planning to cut to tomo nagura. It's hard but not as hard as the tomo above it. Everything clicked. Edge came out laser sharp. Yes finding the right tomo does make a difference.
