### ⭐⭐⭐⭐⭐ Vale cada centavo
*by C***O on 1 August 2025*

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.

### ⭐⭐⭐⭐⭐ S H A R P
*by A***R on 11 December 2024*

This stone gets my knives push sharp with a bit of stropping afterwards. If it breaks I will buy another.

### ⭐⭐⭐⭐⭐ Very fine, hard 1k stone.
*by C***Y on 3 January 2024*

This stone is a smaller version of the Chosera. It cuts at a medium speed(IMO) and leaves a very polished finish for a 1k. It will load slightly over time, but it dishes very slowly. You can easily finish on this stone and have a superb edge. I imagine this stone will last me forever. Also, these Gouken Arata stones are much easier to store and move around being thinner and not having the bulky base attached. I love them
