Picked up this hone at the local flea market for a good price. It was very oxidized(the original color is on the sides) I lapped it flat today. Yellow part seems very hard and I believe the lower is not for honing but just a backer. Did I stumble on a coticule?Attachment 246468Attachment 246470Attachment 246471

the backing looks like a piece of slate and not to be used for honing correct? I ran a scrap knife across the back part and it did not seem a material suitable for honing. The best part of finding this was it came in a package deal a Torry barbers notch, a pre 1891 Joseph Allen and sons with 3415 mark and the stone for $30.00 USD.

Well I guess I picked up my first coti so far I have been using naniwas 1k,5k,8k 12k and a Jnat Shobudani with Asano Nagura that I picked up from Tomonagura on Etsy.

Hey Mack! Youre backing is a Belgian blue stone which in many cases might be usable for honing. It owns less garnets then the yellow side and gives a very nice polishing....Quote:

The backing is a type of stone similar to the yellow coticule top.
Coticules are found/mined between two layers of the purple side and it is called Belgian Blue .it has a different garnet content than the yellow and if I remember correctly they can or do run larger (the garnets )

Doorsch,
so then in your opinion its worth lapping and trying out then?
Mack
As youre stone shows only one corner where it was cut away a bit, i dont see an issue lapping it flat on that side. So just try out and see how its performing....Quote:

That's a very nice coti. I'm betting it will put a heck of an edge on a razor.
You will most likely find that the BBW side will provide a very keen edge that saves a lot of work on the finishers.
Awesome find and great to hear it was found at a flea market! That's a keeper
the vendor sells mostly used cooking stuff like pots and pans and he charged me 10.00 for it saying he had to charge that much because it was old and expensive.

The biggest thing I learned about Coticule's is to finish hone under running water on the yellow side. I learned this from Dr. Matt's coticule videos & it has really changed my honing on this stone. Mine is a slate backed stone so I am going to look for a blue stone to use before the yellow stone. Good luck with your Coti!
