After trying this product, I am thoroughly impressed with its functionality .The fine grit side leaves a razor-sharp edge on my knives. The stone is durable and easy to clean, making it a great investment for any chef or at-home cook. The only downside is that it requires some practice to get the hang of using it effectively. Overall I highly recommend this stone to anyone in need of a reliable sharpening solution for their kitchen or workshop. It's a must-have for any industrial and scientific setting..
