Pretty much every piece that I see is cracked.
Cracked is cracked. I spend an inordinate time picking out knives that are as close to perfect as I can see.
Cracks are an undesirable and unwanted feature of handle material for me in pearl, wood, stag or any sort of horn or ivory. The material might have "character" with the cracks, but to me, it just looks busted.
The other thing is that as others have mentioned, it is usually dyed, but that is not an automatic disqualifier. I mean the dying of stag that Culpepper is doing really makes the stag look attractive, but the reds, blues, greens and such of the giraffe bone look garish and just plain wrong.
