Has anyone tried the Sigma Power Select II stones?
Shopping for a 1K stone and leaning towards the Suehiro debado MD 1K (I really like the 3.5” wide size) when I came across these Sigmas.

Here’s MTC Kitchen’s description for the Sigma Power select II 1K:

“Saicom Corporation has designed a series of stones specifically for the high-hardness, high-carbide, highly abrasion resistant tool steels of the modern day. Each stone is manufactured with a high concentration of quality abrasive in a logical progression order of grits in order to achieve an event, consistent finish in as little time as possible.

The 1000 grit Power Select II is a vitrified stone with silicon carbide as the main abrasive. This stone stands out among others in this line as one of the fastest-cutting stones among comparable stones in its grit range. The structure is quite open and porous and benefits from a short soak, although we've found that simply running water over it for 30 seconds or so is generally sufficient. It cuts very effectively with minimal pressure and its bind is on the weaker end of the spectrum so it's recommended to use just enough pressure in order for it to cut the steel effectively to avoid excessive dishing. This stone was very effective on all steels we tested including Sukenari's HAP40 at 68HRc as well as Honyaki single-bevel knives in the 65-66 range.”

SPECIFICATIONS
· Grit: #1000 (Medium)
· Type: Soaking
· Best for: Carbon/Stainless/HSS Knives
· Dimensions: 202 x 77 x 30 mm (7.95" x 3.03" x 1.18")


And here’s a cool Tools From Japan article testing a CPM-3V chisel on a bunch of different 1K stones (including the Sigma power select):

what are you guys thoughts on this one?
 
I have the 240. Its very thirsty and very fast. However, it gets muddy very easily, and the mud slows it down. The 3k or 10k are on my list to try. Lee Valley carries them.

Sorry, I can only comment on the steel (have no experience with the stone).
Other than to say I'm not a fan of soft Si C stones especially for extra hard steel . . . no . . . I'm not a fan of soft Si C stones.
PERIOD !
Think Norton 220 gray water stone. :thumbsdown: :thumbsdown: :thumbsdown:

This ^
It's easier to get immediately sharp off a harder stone.
Think Shapton Pro 220.

I don't have any of these stones in the lower gits but from what I have been told they are not like a standard silicon carbide stone,I have a Sukenari Gyuto in ZDP-189 and a Gihei Gyuto in HAP40 and the HAP40 is a much easier to sharpen steel then what most people think and say it is to sharpen,I find the ZDP-189 a lot harder to sharpen then the HAP40.

I have diamond stones I use on my knifes in the lower grit's that doesn't tear up the edge and you can use a finer grit diamond stone on a Japanese Chef then what you would use on a pocket knife that has a thicker blade because the blade is much thinner on a Japanese Chef knife.

With ZDP-189 I have really struggled in the past getting a scary sharp polished edge on it,it would be sharp but not truly scary sharp,I found that I was just rushing the higher grit stones and I also found with some Japanese water stones if I use a fine diamond plate and I forget the grit off hand but either a DMT pocket stone that's their finest grit or else a KME Gold Series stone and I use either one of their 2 finest ones that I have to build up a slurry or else the Sigma Power stones I have take a while to start to release enough abrasive on their own to start to cut.

I also have the 6 10 and 13K Sigma Power Select 2 stones and they are good stones and I like them a lot,I use a really fine diamond plate from my KME that I had and I build a bit of a slurry with them and that seem's to help to get them to start cutting right away.
