I ordered a Nubatama Ume 1k in the "hard" variation after watching some of Ken's videos and today I received my package only to find I was sent the regular version
. I'm happy though, as I was very much on the fence as to which one would be the best fit for my needs. I guess I'd have to have both variations in order to tell which one I'd truly prefer, but this regular hardness seems to work much, much better than my old King 1200.....a lot less mud and more swarf on the stone for sure. Overall, I'm very impressed.
