This Ashiya Suita measures 205mm x 75mm x 45mm and weighs 1662g. It is a medium hardness stone that cuts fast and works up a decent amount of mud. It is a finishing stone for knives. The stone leaves a nice polish on harder steel and a mellow white-ish haze on softer steel.
This is one of the most enjoyable stones i've used in a while, and very closely resembles my favorite suita (personal collection) in terms of cutting speed, finish, and feeling while sharpening. The contrast had a bit more darkness to it and was very nice and even. The stone cut very quickly on everything I tested on it, working up a very thick mud. It is a medium hardness, leaving little to no streaking around the curves of bevels. All in all, just a great stone and a pleasure to use. If i didnt already have one very similar to this, I would be keeping this one.
