I tried to insert the photos but gave up, hopefully the links work... on my KME stones(believe on the 300 & 1500) it looks as if there are fissures or long shallow grooves forming on the 1500 w/no visual reflection of diamond(abrasive) across the whole stone. The 300 there are some that are concentrated in the middle section of the stone with an obvious absence of abrasive. Do these guys need to be true'd? Am I just sharpening with matrix on the 1500? Is this normal for these? I've done ~ 6-7 reprofile's and one sharpening with them ranging from chinese 440c to spyderco rex76 & ZDP-189.
 
It is a metal plante coated with a thin layer of diamond particles. Please don't "true" them. You cannot true diamond stone (apart from those resin bond Naniwa stones for example) as you would lap / true solid stones. You just would remove the diamonds and are left with a blank metal plate.

Did they look the same when new? If not maybe you used too much pressure? With too much pressure diamonds can break out of the matrix.

Word, appreciate the feedback. I'm pretty conscious about not using pressure and add water every pass -1/2 pass. No, new they have a consistent diamond distribution. Posted not too long ago asking what the expected life of kme stones were and it just doesn't match up with what I've had with some of them.
