What impress more? Stones or price?

Please give us more information.

Big rocks like that tend to be very expensive, but the fact that there is a plane on it means it is not for razors.

+1.

I know from So that the same nakayamas we use for razors are also used for planes.
And often times, A plane is also used to show how quickly it abrades and how the slurry is formed.

A stone that is good for planes is not hard enough for razors.

It is more correct to say that the very hardest stones, which are still good for razors, are not good for planes because of the "Ji wo Hiku" phenomenon. However, there are plenty of stones that are hard enough for razors that don't cause "Ji wo Hiku", so there are plenty of stones that are good for planes that are also good for razors. In addition, simply seeing the plane on the stone doesn't really tell us anything about that stone.

Frankly speaking I thought, that everyone will be impressed by the price of the stone, 4 200 000 yen is a little more than 50 000 US$ (almost 52 000 $).
