I find the higher microns paper wear quite well, but the 5 and 1 can tend to rip.
I know these are polishing grades, but it does seem the more you polish, the more you sharpen, the higher the ripping incidents become, and Yes that is using the paper as Matthew suggests in his Narex chisels set up YouTube video...
Cleaning off is a pain, but sticky solvent remover, white spirt etc will clean up off granite...
I've been using a 30, 15, 5, 1 set of papers and the results are fantastic...
I also make up a solution of honing water with the additive as suggested, in a spray bottle as a lubricant..
Cheers!
I find that any paper finer than 1500 FEPA will cut/tear if the (by now rather sharp) edge goes into it, even slightly. I would (therefore) advocate a jig is using these papers.
Edit; I see in the video he IS using a jig.
