The fine grit type ensures a precise and sharp edge without damaging the knives.

However, it's made of plastic, which might not appeal to those looking for more durable, metal-based sharpeners.

However, while the product claims to be the world's simplest and safest, some users might still find initial use a bit tricky if they are completely new to manual sharpeners.
