I'm thinking of getting a cheap hone for touch ups, either a Chinese 12000k or a Dragons Tongue and although now you can buy both with a rubbing/slurry stone is there any advantage (or disadvantage) to using a different type of slurry stone?
If you use a diffirent rubbing stone it needs to be of higher grit than your hone or your slurry will become contimated with a lower grit so you might be making more work for yourself.
Good advice. Or get a credit-card size diamond plate and use that to generate a slurry from the actual stone. Remember to go over the whole stone with it, though, or you will have a low point after some time.
