The fact that most people won't even use the BBW side of a stone when it is known to be used for knives especially and sold marketed that way by the mine should tell you that a piece deemed unusable by the mine would not be worth the effort even if it actually did anything.
Well, that same seller put up a misidentified bbw the other day almost a month later.. The bbw that released from this.. I'm disgusted I paid $21 plus shipping for a bbw but the dimensions was making finding one a pain.
I wouldn't bother with the backing, personally. That's plenty thick to survive on its own. I've owned tons of hard pure coti's way, way thinner than that. Honestly, I'd lap the back and use both sides.
There's no point in it really as the back is probably fairly similar to the front. I like hand honing so I like s taller hone in general. The bbw seems quite red so whike it still annoys me it may well be interesting.
