Does anyone else ever feel crack in their sharpmaker ceramic stones, or ultrafines

I have been using the sharpmaker ceramic and ultrafine stones for about half a year now. I mostly use the 2 flats and on every single stone there is one good flat and one flat where I can feel cracks or imperfections. Will these "cracks?" in the stone damage my edge or is it fine to use it, because right now I can only use 1 flat on each stone and they gather steel quickly.

any help or insight is greatly appreciated, Thanks in advance
 
I don't know about any cracks but there some nicks on my stones. From what I have read on it before it should not mess with sharpening.
 
Should be fine. Mine have picked up a number of tiny surface nicks/chips (not really visible, but you can feel them with your fingernail or when drawing the blade across them) over time and use, and they still sharpen just fine.
 
Mine had a fine rod that had a "pimple" if you will. I rubbed it on the flats of my Grey rods to flatten it. IMO, if you can feel it it will effect your edge. There should never be a bump due to your rods.

That sums it up. If you can feel the 'speed bumps' or 'potholes' under your edge as you're sharpening, that'll always detract from results; nothing good can come of it. It needs to be fixed, one way or another. Ceramics are hard enough, that any sort of spike in pressure can roll/chip an edge immediately. If the bumps in the rods don't rub off, as mentioned above, Spyderco has usually been good about making it right, with an exchange.

Thanks for all the insight, I guess its not only me experiencing imperfections in these stones. nevertheless I still love them and will continue to use the one good side.
 
When i got my 701 profile set couple years ago, i immediately felt quite a few tiny "pimples" on the fine rod that seemed to slightly "catch" my edge. I was bothered.

Since i didnt have the option of a replacement, i just used it. Felt better when i reminded myself of Spydercos QC. One anomaly would be odd, but since i noticed the effect all over the stone i assumed it was normal.

I very rarely notice this effect anymore. When i do, its the areas with the least use. Maybe its just a manufacturing byproduct that needs to wear off a brand new stone, like breaking in a DMT.
