I have more pictures - already made my comments in the diamond hone thread, but I figured one thing some folks may find interesting is what the back of the same tool would look like if sharpening with a brand new hone, and then with one that's broken in/worn out (this will happen with all diamond hones other than those that are a sintered layer - and the sintered layer stones are expensive and would go out of flat, so forget about chasing them).
At any rate, here is the spectacular 400 grit new hone with brash grooves cut:
And then, the exact same stone from the same maker but with quite a bit of use (with these stones, you more or less use the 400 side like a 1000 side later, and the 1000 side becomes sort of a slow hone (this happens with ezelap, too - I have difficulty finding something for my 1200 eze-lap stone to do.
At any rate, here is the same brand but well broken in.
And then, for comparison - a worn out DMT 325 grit side from a duohone:
The X pattern in the bottom iron is simply from a trick that you may try with a diamond hone that's slowing down, Change the direction of the grooves by moving the iron orientation so that you're cutting across the channels rather than with them.
