What’s Inside a Botan? 


People think I’m crazy when I say that Botan can have a layer of sand inside of it. 

Well – it’s true and here’s proof.

This stone was soaked it overnight to get the sand to swell up so I could split the stone as cleanly as possible.  

In use, one would not want to make slurry using the narrow sides of this Nagura. Instead, using the stone with the sand-layer parallel to the Honzan would be the right thing to do.

When the Nagura was worn close to the line, it should be lapped clear of the sand and then the issue would be gone.

Not all Botan have sand inside of them like this, but it is not an uncommon situation.
