So as some of you may know you can still get the Naniwa super stone series with the plastic base included. Are these any different than the earlier version of the super stone? I have the 10,000 stone and I believe there’s a mention of a ceramic binder as far as I can tell (ceramic/resin combination?). I kind of enjoy using the stone because the plastic base is a bit of a novelty. Does anyone else have any experience or information in regards to the composition of the current iteration of the super stone?
