I am a professional sharpener. This did an excellent job in sharpening some chisels. I would also use it on knives and axes.

When I first received it I got out my pocket knife to sharpen, only a few swipes and it was back to its original sharpness. I also sharpened every knife in the house, and my wife couldn't believe it, and my chisels never been sharper.

I would highly recommend this product. We sharpened every thing in the house. It was easy to use and worked excellent.

Diamonds are a woodworker's best friend! The first step to successful woodworking is sharp tools. This diamond whetstone is very effective and makes the sharpening process a minimal effort.

This is by far one of the most useful tools to have in any shop. The ease of use is such that even a complete novice can sharpen knives like a pro.

The Diamond Sharpening System performed very well. I sharpened my hunting knives in less time with it than I did with my oil stones that I have.I also have an electric knife sharpener and the Diamond stone out performed it. I sharpened my wifes kitchen knives and my Mother-in -laws knives, they were very pleased with the results.Very easy cleanup of the stone when done. I am very satisfied with the Diamond Sharpening System. I recommend this product.

I used it on everything from my knife collection to my bench chisels, turning tools and planes. It was easy to use and gave a superior edge without the mess that my oilstones make.

Upon receiving your product I immediately went to my knife drawer and proceeded to put a very fine edge on my knives. Not having to get out my oil stones and the mess involved with that was a HUGE benefit!
