Soft Narutaki-san Awase-to (Natural Whetstone) This type produces a considerable amount of viscous mud, which brings out the steel's surface beautifully, creating a stunning, cloudy finish. I believe the sharpening feel and the final result are both unique. The sharpening feel is very adhesive, which I think is perfect for those who like that sensation. It didn't quite suit me, so I'm putting it up for sale. You can sharpen without a nagura (whetstone dressing stone). I've also included photos of blades sharpened with it, so please refer to them. There is a crack, but it has been repaired and treated, and there are no problems with use. Returns and exchanges are not accepted.
