Thread: Chinese 12k leaves edge dull?

I am a defender (or inventor? I don't really know.) of the theory that the PHIG performs best (if at all) when lapped to perfection.

I came across this about three years ago when I bought my first PHIG and everybody was raving how good or bad it was.
I didn´t get good results with it until I finished the surface. When you slide your fingernail across the stone and you feel a little unsmoothness,
you´re not where you want to be with the PHIG. It should feel as smooth as glass.

I recommend to lapp the stone thoroughly. This will take time, energy and a lot of sandpaper, because these will wear out quickly.
Get 240, 320, 400, 600 and your 1000. That should be good for the start.
First step is to make it flat.
The second step is to erase all scratches and high spots from the prevoius papers on the sandpaper.

Now for a reason I do not know coming from a 1k sandpaper the stone still does not shine or feel as smooth as glass.
That´s where I take out my old BBW (credit card size) and run it across the PHIG for hours (literally).

This can be done by other hard and fine naturals, too I guess. You want the PHIG to be like a mirror and feel like marble.
Then it performs at its best. This has worked for me twice now and seems to work for others as well
