Thread: BBW/Coticule

So I placed a last second bid and won this old BBW/coti. I implore you fellow rock hounds, did I do ok?

I know the coticule layer is quite irregular but sometimes that's not a bad thing.

Use it with the BBW corners away from your honing hand and it will be fine.

What an odd specimen. I think you did well. It's thick but on a taper. Much cooler then your run of the mill coticule.

Thank you. My thoughts exactly. It's an odd one but it seems to have a good thickness of coticule where it counts. As Utopian said I'll just keep the BBW area on the far side when using.

Very unique looking stone, well done. I would say don't worry about the protruding bbw, as usually the bbw close to coticule side is harder and doesn't auto slurry, I would recommend that you rub it using a Slurry stone after lapping to smoothen the bbw.

Waiting your update when you get it.

I don't think it will be an issue for you. It's a very cool coticule actually. You got quite a lot of material for your money even though the deposit is heavily biased.

I'd use it as is and not worry about hitting the bbw. I've finished razors on the blue side with nice results.

You did good, I think, plenty of coticule left. I wouldn't worry too much about the blue bits, as it will not degrade the coticule edge. This because the slurry on the Belgian blue stones does not dull the edge even close to how a coticule slurry does; this slurry dulling is one of the main reasons why you dilute the slurry on a coticule. Also, due to this a bevel set on a BBW will usually be a tad sharper than one set on the yellow. It does take a while longer to get a good bevel, though.

On water, the blue stones are usually dead slow, with minimal impact on the edge. Anything that happens on water only will be mainly due to the yellow part. Belgian blue stones in general are slower than yellow coticule, so anything that would happen to the edge on account of the blue would be corrected by the yellow, I would think.

AljuwaiedAK, any BBW I have tried auto-slurries like crazy compared to any yellow coticule. How are you so sure about the hardness of BBW and its relation to how close it is to the yellow, when, among other things, there are lots of different blue and yellows? And how do you go about testing the auto-slurrying abilities of Belgian blue when surrounded by yellow coticule?
