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 was impressed at how fine an edge it put on my filet knife in such an easy way.

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.

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

I was used to using ceramic and steel sharpening kits. I'm impressed with the ease of use with the diamond sharpening system. I used it both wet and dry and it performed great both ways. With just about a dozen strokes I was able to sharpen knives that normally take 5 to 10 minutes apiece. It's also so easy to clean after use. Just rinse it under running water and wipe dry. Great Job!

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.

This product is a great sharpener, it is very versatile and easy to use - a must have for every household!

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.
