This review is from Ken Schwartz:

It's 205x75x50 mm in size - a brick sort of burnt orange in color. And it works like no other coarse stone I've ever used. It cuts metal fast and it dishes slow.

It cuts faster than the 120 pro or GS, faster than the synthetic Ohmura and WAY faster than other finer grit stones like the Beston 500, Chosera 400, and other 220 and 320 Shapton stones. It leaves a coarser finish than the finer grit stones I mentioned, except the Beston 500 which doesn't give as fine a finish, cut as fast, or dish as slowly.

So far it hardly dishes at all. This is perhaps its most valuable trait. I've used it on a bunch of CPM 154 Addicts to set bevel angles and a bunch of Aritsugu-As - and I have yet to have any mud from the stone to show for it. Have yet to need to lap it! The same amount of work on any other stone would give me a mud puddle. Burr generation is rapid.

I followed it with a Shapton GS 500. It was an excellent combination. I would also consider it as a starting point for going through the Chosera series - following this stone with a 400 Chosera for instance. From there I switched to some natural stones (aoto and Yaginoshima asagi) for these initial sessions with the Bamboo 150.

The 150 Nubatama Bamboo is a finer scratch pattern than the XXC DMT or Atoma 140 and is a perfect followup for them.

It is a porous stone. I would suggest soaking it for about 5 minutes first. That fully saturates the stone. You will need to add water to it to keep it wet. It isn't recommended that you leave it soaking as it doesn't require it.

This is a stone for removing metal. It leaves an edge suitable for slice cutting paper or coarse work. Very "toothy." It is too coarse for a final finish but excellent for repairs - chips and tips. Strongly consider this stone for work on single bevel knives.

3  I hate to be the jerk. Cool stone though., May 22, 2015
Posted By: Max S.

Been using this stone for a while, also been using it on the edgepro and honestly the more I use it, the more I would rather just use a diamond plate. The stone dishes so freaking fast, and it takes forever to wash the abrasive sand it leaves everywhere! I mean the stuff sticks to your skin, gets in every crack and crevice in your work space. It is somewhat like working with loose silicon carbide, but finer.
Now on the good side, you get a HUGE stone, and the thing does its job in terms of abrasion. It simply does not matter what steel, heck this thing may be able to grind ceramics, who knows. Its hard to say if it is a standard carbide stone or not, perhaps its a carbide stone with a special binder? I don't know! It has its drawbacks, I don't know why the description says it is wear resistant, how could it be? Look how porous it is! If you are like some people out there and despise diamonds, this is your best bet for a coarse stone.

5  Fast cutting stone, January 24, 2015
Posted By: Jacko

While this is an extremely fast cutting stone, I had to keep it in the stone tray with water to keep it hydrated. If I used it with my Shapton stone holder the water keep flowing through into the tray.

The stone cuts fast, stays flat and leaves a nice fine scratch pattern for a follow on with my Shapton Glass 500 stone.

A beast of a stone. Fast and efficient. You can go straight to a 1k is you lack a stone in between. Can't say enough good things about it.

The stone is literally a large brick. It cuts fast and leaves a scratch pattern that lets me go to my 1k stones. Great buy!

Upon first holding it it is literally like a brick in size and weight. Everything Ken said is true EXCEPT it did bring up mud for me. But be it said that I was THINNING and the mud that does come up keeps cutting and leaves a cool sandy finish.
