Based on my experience this whetstone sharpener is a game-changer for anyone in need of razor-sharp tools. The multi-purpose whetstone not only sharpens my knives to a precise edge, but it also works wonders on other tools like scissors and chisels. The waterstone feature keeps the blade cool, preventing any damage from overheating .The only downside is that it requires some practice to use properly, so it may not be suitable for beginners. Overall, a great investment for any professional needing a dependable sharpening tool..
