wow, I have not tried many stones but I re-proflied my one pocket knife that i carry every day, it is ZDP-189
it had some chips in it (small)
I started with the 220 and i was already able to cut paper cleanly !! I could never do that with the stock stones
I move to the 320 and i was able to push cut paper from about 1/4 inch out
I took this kife all the way, 500 > 1000 > 2000 > 4000 > 8000 > 16000 > .25 micron on strop (nano cloth)
this is the sharpest knife i have ever done.
The ZDP cut like butter and burs where so easy to get off with these stones
when i look close i do see more scratches in the mirror finsh but i think this will just take some practice to get get cleaner
I should also say it took about 1/4 the time as it use too !!!
do you guys leave the slurry on these to get best result (for mirror finsh) or leave it off?
