I recently bought a Hideriyama Koppa from JNS. This one actually:

One of the tricky things with koppas like this is the edges. You still want to be able to get close enough with the heel of the knife to get a uniform sharpening.
Not to much of an issue with this one, but still.
Also I really wanted some fingerstones from this one as Hideriyama is notorious for the great contrast it brings out.
So I decided to trim it down a little:
As you can see, I sitll have a sizeable koppa, and the source of quite a few finger-stones.
The cut edges have been rounded. Here is an example of the result:
The fingerstone stands out on this pic as it is still wet.
So I am a happy camper: I got a great stone for a good price.
It is now easier to use AND I´ve got quite a lot of good fingerstones :doublethumbsup:
