Natural Stones

Medium to high grit powder of assorted quality stones. Ideal for fine-tune polishing or to remove light rust. Can be applied with numerous applicators like a cotton ball, rag, cork, felt, balsa wood, etc. Water is needed to apply. May require further powderizing of any potential slightly larger bits. Use first before Ozuko powder and after Suita powder.

Notes: This is slightly coarser and softer vs. its finer and harder Aoto sibling. These softer versions will be faster cutting, create more slurry, leave slightly deeper scratches, create darker/hazier Kasumi, and would be used earlier in a polishing progression. Softer stones tend to be easier to use as they are more "forgiving" than harder stones, thus easier to learn on. These are "true" Aoto of quality, consistency, and provenance. Given their price they are an awesome way to get involved with natural stones.
