I’m practising sharpening kitchen knives really sharp. So not just pulling along a sharpening tool but really multi stage sharpening and honing. up to 2000 grit. Grabbed some old knives that were damaged and repaired a point and sharpened through 200-800-1500-2000grit.
And for fun between each step photographed the cutting surface to see what I did.
m43, lumix 14-140mm and two extension tubes (16mm and 10mm on top of each other) at f9. you can’t get cheaper macro 
(manual focussed at 140mm an tried focusstacking but AF was lost on this level.)
But you can use it:(these are stacked by Silkypix v10 pro)
Tripod needed but it’s lot of fun to do and those extendertubes are cheap!
Ok Back to my knives!
image where fast editted: autoexposure correction, clearview, fine contrast, microcontrast.
first the uncut you see the machine applied grooves. (sawdust as “dirt”)
then the coarse stone:
(i see i was searching for the right angle, nicked the top of the bevel wile i needed to touch the cuttingedge.
better, reasonable nice bevelconcistency.
Then 800grit first honing:
this is real edge detection!!!
then 1500 grit honing, again not perfect.
but i made a “burr” zo i touched the end of the edge.
Not perfect in concistency but it will do.
then finaly near stropping fine honing:
Then i stropped along a old jeans, to get rid of all those small steel flakes.
(i need a polishing tool to finalise)
does this have anything to do with PL? 
nope!
except there optical module and deepprime is exelent!!! 
100% look:
wetstones surface at 100%
