Impressive little stone is my summary. I only wish I had a larger one, for this is tiny, yet it produces a better edge for me than a Charnley and comparable to my Escher after a mere 50 laps following my finest coticule.

I have been playing with it for a couple of days now on 10+ razors. What is this little thing? If Sham or Jimmy lived in the UK, I'd have been round with it long ago!
