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.

If I would have known how easy it was to have a sharp knife, i would have bought one of these a long time ago. Highly recommended.

Over the course of many years I have obtained and used a variety of knife sharpeners. The DMT 6" diamond whetstone sharpener is far superior to any other I have used. There is no substitute for sharp knives and there is no substitute for a great sharpener. Just a few quick strokes maintains a great edge. What more can you ask?

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.

ease of use, great edge, simple instructions

Just a few light strokes across the sharpener and I restored several knives that I thought would not hold a edge any longer. Well worth the price. This sharpener pays for itself.

The Kitchen knives were the first test. I consider myself a novice at this. I've used knife sharpeners before with not so good results. This time they got sharpened and my wife was showing me how nice they worked.

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.
