I have had this stone for quite a long time, I believe it was one that my parents gave me that they had floating around the house.

It's a wonderful finishing stone, and I have been using it to put a final edge on my knives. It is smooth to the touch, about comparable in feel to 8000 grit micromesh paper that I have.

Is this a barber's hone? It is about 8"x2"x1/2" and has no markings of any kind. It has a very hard feel, much denser than my other stones. Any idea what it is made of? And for the record the chip was there when I got it.
