Anniversary Sale 2

Brand: Tanaka Toishi 田中砥石工業所.
Producing Area:  Kyoto/ Japan
Mine: Kouzaki
Appearance: Certainly a base of blue, hence the name "Ao"-to, "blue" stone. These softer versions tend to have a tint of red/brown to them, a decent indication of their softness level.
Size: 175mm x 52mm 54mm
Weight: 1031g
Grit Range: ~2000

1-5 Scale: 1 = Less, 5 = More

Hardness Level: 2
Scratch Depth: 4
Speed: 4
Wear Rate: 3.5
Self Slurry: 4.5
Thirst: 3
Consistency: 5
Feedback: 4
Ease of Use: 4

Recommended Usage: Early/mid polishing sequence, hazy Kasumi, textured edges with solid bite.

Notes: This is slightly coarser and softer vs. its finer and harder Aoto sibling. These softer versions will be faster cutting, create more slurry, have 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.

Brand: Tanaka Toishi 田中砥石工業所.
Producing Area:  Kyoto/ Japan
Mine: Kouzaki
Appearance: "Aoto" means "blue stone", thus the blue foundation. Finer examples can be a true solid blue, while some can have subtle hints of purple or green, while softer examples will have more red/brown tones.
Size: 201mm x 57mm x58mm
Weight: 1528g

Recommended Usage: Mid polishing sequence, frosty Kasumi, mid sharpening for push-cut tools, keener edge with a little bite

Notes: This is finer and harder vs. its softer, coarser and generally slightly reder Aoto brother. While finer variants will typically be marginally slower cutting, they will have shallower scratches, last longer, provide brighter Kasumi, as well as be better for push cut tools. So this option will be more ideal for mid work.
