Yes, sorry kingreverent, I realized that my sentence isn't very clear. That one is not a progression, but just the list of the most common stones between italian members. Regarding small increments, well, I've to say that I'm doing quite well with my small set (DMT extra fine, BBW and two different Coticule) so I guess that small increments are just one of the possible approches. Is it so? :confused:
EDIT: one of Mastro Livi suggestions is that hones (sintetic and natural) must be kept in water for their entire life. He also gives an important place to strop pastes. [I don't like pastes and keep my belgians in a nice case.. :p ]
