Notes: Aizu have quickly become a fan favorite in the past few years. They are somewhat abundant (getting less so), very consistent, quickly give great toothy results on edges, and can be use a pre-polisher. It is somewhat hard, so some skill is required not to scratch too deep when pre-polishing, and to prevent skating (slipping on the harder surface), but is not that difficult either. It's hardness lends itself well to razors and tools earlier in the sequence. Best when used with a forced slurry. A really good option for new and experienced users.
