Does anyone know whether the Nubatama Bamboo 3,000 grit stone behaves like the 1,200 and 2,000 grit Nubatama Bamboo stones? That is, does the stone behave like a a soft Japanese natural, or does the 3K behave like a hard synthetic stone, like the Nubatama Bamboo 1,000?

The Nubatama 3k is the same formulation as the Nubatama Bamboo 2k, but finer and will act in a similar manner. In this way this addition to the series can act as a final polisher for certain applications and as a smaller jump for some natural polishers (awasedo). Much like the logic for the Chocera series, you would use either the 2k or the 3k but not both in a sharpening progression. Which one you pick would depend on what preceds and follows it and the abrasion resistance of the steel you are sharpening.

Thanks, Ken. For What types of steel and blades would you recommend using the Nunatama Bamboo 3,000 grit instead of the 2,000 grit?

The indications for steel types should be the same. The resultant edge would be more an issue of simply the grit desired. Thus you might select the 3k as a final finisher, whereas the 2k might require an additional stone. It really is just an option. So the 3k might be a fine choice to precede a natural polisher (awasedo). It really is the same issue as why you would use a 3k or 2k stone in a sequence in general.

Please check out the 3k bamboo video I finished this weekend. I specifically tried to answer the questions you posed. While this stone is superb for carbon steels it turns out to be an excellent all around stone too. A bit of a splurge to use on a cheap crappy knife but it will do the job. But on a carbon knife it really is a superb stone.
