Nubatoma 60 Grit Stone
205mm x 75mm x 50mm Here is a short review of the stone by Pro Sharpener Ken Schwartz:
I had a chance to try out the 60 Grit Nubatama UME waterstone and did it on video. I did this video straight out of the box unused, so you get to see my first impressions of the stone.
In this video, I am demonstrating and using the 60 grit Nubatama Stone. It is a member of the Ume or Plum series of Nubatama stones, the coarsest grit in the series. An extremely versatile stone, capable of being used for rough work, including tip repairs, major knife edge reshaping, and stone flattening. The speed of this stone for these tasks is PHENOMENALLY FAST, accomplishing it as quickly as a belt grinder might do it but with NO heat involved.
This 60 grit stone does not dish quickly, is porous and accomplishes it's tasks extraordinarily fast. This is easily the finest quality ultra coarse stone I have ever used.
I also demonstrate a technique for quickly deploying a stone normally soaked for a bit immediately using a water drip from the sink. And a means of deburring using the stone you are sharpening with without resorting to breaking off the burr ...
If you need to remove a LOT of metal and don’t want to use a belt grinder this is the stone to use. VERY quick cutting and yet dishes rather slowly for the type. Water consumption is very high. It should be noted that if you are new to sharpening then I would get one as you can quickly mess up your bevels and end up making a whole lot more work for yourself. But if you aren’t and are looking for a very good,very fast cutting stone this is the one. And the usual great service from Mark.
This stone is better than having a belt grinder. It removes metal like a belt grinder,but without the heat. Highly recommended.
