This stone has been over a year in development. It is a 'cousin' to the 1k Speckled Ume stone - one of the most popular Nubatama stones. I already have two 2,000 grit Nubatama stones so why a third one? Well the Bamboo 2k is expensive - works exceptionally well with carbon steels. The black Ume 2k is a brick size and also somewhat expensive because it is large, and somewhat soft, so if you want to go from 1k to either 2k or even 3k, your choices are expensive. Enter the speckled 2k Ume! This is a versatile stone, suitable for a wide range of sharpening needs!
The stone should be similar but just finer to the 1k Ume speckled stone in medium hardness - perhaps a bit harder. It is considerably harder than the 2k black ume stone. This stone should fit that sweet spot of working well over a very wide range of steels and knife types.
I envision this stone as a perfect followup for the 1k speckled ume and as an intermediate before going on to a 5k Bamboo for instance.
It will also be an excellent precursor or stone preceding using an aoto in a natural stone sequence.
