It says this right in their product description...
Perfect for flattening plane soles, irons and chisel backs—even conventional and water stones
Hard to say....Is the bevel set do you know?
What you might want to try is to do some circles (Watch Lynn or gssixgun's videos on Youtube) on the 4k with a little slurry raised (you can use just sandpaper to raise a slurry). After 40x circles on both sides, then follow it up with 10-15 X-Strokes and see where you're at...
also the gold 8k side has dark patches on it
yes i have tried this circle method without sucess
