I bought one a year or two ago.
It is a nice barber hone, finer than any other I have.
As Sham will be able to confirm, the thing that makes this one a bit special is that it will take an already shave ready Edge, like off of a Y/G Escher finished Edge, and actually improve on it's sharpness.
Weird, I know, but it actually does...
It can be argued that it actually takes the edge too far.
Either way, I will keep mine as part of my retirement plan;)
