Naniwa NA-0040 New Arata Professional Medium Whetstone #400 8.3 x 2.8 x 0.6 inches (210 x 70 x 15 mm) Green

Awesome stone, this is my first naniwa stone and I can see now why the make a big deal out of it. Cuts fast, dosen't load up and leaves a good edge on the knife. The stone is supposed to be a wet and go stone, but it needs a quick 1min soak in water,but no big deal still a Awesome stone.

Pedra sensacional, muito gostosa de usar, proporciona um excelente feedback, aveludada, sua ação na remoção de material é rápida e fácil manutenção, não retém muitas partículas na superfície da pedra.

Great stone for the price. Easy to use and sharpens in no time. Not a bulky stone and feels soft on the edge

The plastic case to protect the stone was broken and there’s a small chip in the stone but all in all it is good as what you expected from the brand! Thank you

Once has to learn to use these 'stones' - splash them rather than soak them (for, some stones, such as these, can crack if soaked); get the sharpening action, and angle, correct; learn how to clean them. Now that I have learnt those things, this stone, in conjunction with a 3000 'grit' stone, serve me well.
