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

It is quick and easy to use and produces a very sharp, clean edge. Requires much less work than standard whetstone. Tested it on knives, chisels and gravers and it produced excellent results.

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.

It is very simple to use and does a great job of sharpening knives and chisels. I used it on Lathe turning skew and it was easy to do that and it produced a very sharp edge.

Made in the USA means a lot! It sharpens quickly, whether you need to remove a lot or just a "tune up" on the blade edges. Because it's manufactured flat, it is excellent for planer blades and chisels. The ability to sharpen dry or with only water creates less of a mess than other types of sharpening stones. The no-hassle guarantee is a definite plus, though I would be surprised if you ever needed it.

I had several tools that needed sharpening and was able to quickly sharpen the tools to like new condition. This is an essential tool, for my toolbox. I wish I had purchased one years ago as I have been able to restore a lot of tools to new condition.

I received this during ice fishing season and used it exclusively to sharpen my fillet knife while cleaning fish. It put an excellent edge on the knife with just a couple of strokes. It has lived in the kitchen ever since and I will probably have to steal it once hunting season starts!

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.
