Sharpmaker Question

I have one of the original Sharpmakers, when there was only one angle. My question is this. I have an XM-18, gen 3 flipper,. 3.5. Its pretty sharp, but I like to keep it really sharp, so I use the sharpmaker on it a lot, normally with the white stones. I find its better to touch it up a lot then let it get dull and have to work on it for a long time or go back to the coarser gray stones. On this knife, or any other quality knife with any of the modern stainless steels, am I removing a significant amout of steel by sharpening it a lot?
 
IIRC, the grey medium rods are 15 micron and the white rods are 6 micron. So it should be impossible to remove any significant degree of metal unless you keep at it for hours nonstop, which I hear is usually what it takes to reprofile an edge with the grey rods. If you're concerned, buy the Ultrafine rods to maintain your edge. At a measly 3 microns, it would be akin to using a strop.
 
Ceramic hones remove little metal (comparatively), and produce the best results at light pressure. Used as such, I wouldn't worry about doing any real harm to your blade.

The caveat to that is, if you feel you're having to do a whole lot of grinding away on the Sharpmaker, just to create a decent edge, then using a somewhat coarser hone to re-establish a good bevel is probably in order. If some additional metal has to be removed to put a geometrically sound bevel on it, then so be it. Once the bevel itself is in 'good shape' (literally), that's where very light touch-ups on the Sharpmaker will really make the edge pop. Then, as mentioned above, stropping can take the edge even further.
