Excellent quality product as you've come to expect

Best I have found
This replaces the same maker's stone that has worn out over many years. This should tell you what I think of this unit. It does the job well and is made well.

Must have for any house
This is the 2nd product I have purchased from this company and both have sharpened everything I have thrown at them. The 1st one I bought 20 some odd years ago still works great, had to buy 2nd for my son so he would quit stealing mine. The quality haven't changed in all those years.

Quick, easy sharpening tool
I am a big fan of the 6 inch diamond whetstone sharpener. I have a number of smaller compact DMT sharpeners, but this one lives between the kitchen and workshop. Wet or dry, it delivers. It literally only takes 5-6 swipes on a well maintained blade to keep it sharp. As a matter of habit, I give each knife a sharpen after every use. It takes less than 20 seconds to maintain an edge. DMT products are consistently excellent. I cant find a thing wrong with this sharpener. I keep the folding coarse DMT sharpener in my leatherman pouch and a bi fold coarse/fine in my hunting pack. If you like a sharp knife without a lot of hassle, go with this product, you wont be dissapointed.

Great product
I wish I would have bought it earlier, instead I wasted time and money trying to buy cheaper. I'm very happy and my knife is very sharp.

Works great, easy to use, skip the hardwood case
I love this whetstone. I've had a fine version for years and just added the extra fine to take my kitchen knives to the next level. Easy to use, doesn't require oil or water, but I like to use water nonetheless. But skip the hardwood case. You can save $10-$15 and just get the cheap plastic case. You'll take it out of the case to use it anyway. They left the opening on the case big enough that the stone slides back and forth about 1-2mm as you use it, making it difficult to keep in place on a hard surface. Just put it on a damp towel or in a vice and you're good to go.

Great sharpening stone
The diamond stone cuts very quickly and efficiently and it's wonderful not having to worry about the stone wearing away over time and having to be leveled. I haven't tried the diamond stones for the finer grains, for which I'm still using Japanese wet stones, so I can't speak to the fine honing capabilities of the diamond stones, but the coarse diamond stone makes short work of the initial process of removing burrs and dings from the blade, the kind of work which can take hours with the finer Japanese stones. Clean-up is easy, they require no soaking, all in all, a very helpful and handy stone to have.

I am very impressed with this DMT 6-inch diamond whetstone. The build quality is excellent, the surface is perfectly flat, and the sharpening speed is much faster compared to traditional stones. No need for soaking or oil – just a splash of water is enough. The stone cuts very consistently and gives predictable results every time. I use it for woodworking tools and knives, and it handles everything easily, from quick material removal to fine honing (depending on grit). Compact, durable and extremely practical in the workshop. Highly recommended for anyone who wants a fast, clean and reliable sharpening solution.Excellent sharpening stone – consistent, fast and reliable

Funciona tal como se anuncia. Lo he usado para afilar mis cuchillos de cerámica y los deja como nuevos. El estuche de madera también es de buena calidad.
