I have a bench stone, I guess that is what it is called.
I bought it about 20+ years ago and gave it to my granddad for Christmas.
He passed away...
I received it...,
I never used it (I use a Lansky and Gatco), I am not much as a sharpener, LOL!!
It is still in the box/case/cover "if" I remember correctly.
It is in the closet, I will have to look for it if you are interested.
I believe it has 2 or 3 stones, 3 "I think".
It is not new, he did use it.
I remember how he could sharpen a knife!!!
You could actually split a hair with it. It looked like hair would literally "jump" off your arm. Touch a hair half way up and they just jumped. I wish I could do that..., If I could, I would keep the sharpener, LOL!!
Let me know if interested and I will look for it
