Ozuku Lv 5++ Old Barber's Super Finisher With Toishi Dai
I usually don't have interest in super hard stones for razors, when I do it's for good reason in special circumstances. This old Lv 5++ Ozuku is a perfect example. This is a very pure stone and has good feedback despite being so hard. This can be increased with some glycerin in the water to your tastes. It has absolutely no water absorption and is a final polisher of the best caliber. With koma nagura this hone works best dilute to just the hone itself and finish on water. I would recommend against a diamond plate slurry on this stone because it is so hard and the finish it imparts is increased by it's very well burnished surface. It is remarkably flat for such an old hone, and I have polished many edges on it. The good thing about this old stock ozuku is that it is both very pure, and the particles less scratchy than most ozuku, leading to a finer polish and more refined edge that is not only super sharp but also smooth. This with blow away a 20k synthetic any day in terms of both sharpness and edge comfort. Just like all the razor stones I put here for finishing, it'll blow an escher away too.
The scent of this stone is very pleasing as well, it smells of a lake after rain.
There are a couple tiny (4mm or less) shallow (under 1mm) chips out of the edges and corners, those too are burnished and do not affect honing. If you like to remove them though, you can carefully lap it and prepare the surface with a #1200 plate, then burnishing with another hard stone or nagura and then steel until the surface polishes back up.
