Review on 💎✨ Efficient Diamond Whetstone Sharpener: DMT W6FP Delivers Superior Sharpening Results by Arturo Reyes

I hand sharpen my kitchen utensils with a DMT diamond stone and a combination Japanese waterstone: Woodstock D1130 grit 1000 and Japanese waterstone 6000 grit. "Fine grit" is quite aggressive for a typical kitchen knife. A friend of mine has a chef's knife with a broken tip (1/4 inch) and a chipped edge, and I was able to fix the tip and blade with this "nice" stone. DMT diamond stones require a small amount of water when sharpening. This prevents metal particles from sticking to the grinding surface. In my opinion, water lubricated stones are superior to oil lubricated stones for two reasons. First, they are easy to apply with water and then clean. Second, water is less slippery than oil, so it's safer to sharpen a knife with wet hands than with oiled ones. DMT manufactures diamond stones with discontinuous and continuous surface. This applies to the first. For most applications, a discontinuous surface is slightly better as fine metal can enter a slightly depressed area and stay off the sharpening surface. This improves sharpening performance by reducing flushing frequency and removing fine metal from the surface. If the blade is very small, it will get stuck in the recess. For these small bladed tools you will need a solid surface diamond stone. I have uploaded a closeup photo of the diamond stone. The 6" x 2" stone size fits most kitchen knives, although a wider stone would be better. The recessed red dots are 1/8 inch in diameter. In my experience your blade needs to be at least 1 inch long to comfortably use a discontinuous surface. I bought this DMT diamond stone for $35. I find this diamond stone very versatile. It cuts quickly and evenly while still giving you complete control. The DMT grinding surface is extremely flat, which is why I also use it to level my Japanese waterstones. If you have never used a diamond stone you will be surprised at how fast this stone can cut/sharpen. Of course I was. I have an alumina oil stone and have to slide knives onto the stone to sharpen them. And I just move the knives back and forth on this diamond stone. This saves time, energy and improves the sharpening result. To be honest, it's probably safer too. Since diamond stones cut faster than other stones, I would like to suggest that new users check their progress a little more often. Although this DMT stone is advertised as fine grit, the grit is 600 (25 microns) which is too coarse to be a knife finish stone. Knife blades sharpened with this diamond stone should be polished on smaller stones. If you enjoy sharpening knives or tools, I recommend this or one of the other diamond stones. You will not regret buying a DMT diamond stone. *Updated December 27, 2009* I noticed yesterday that my Shun bread knife has two very small but visible chips, I don't know where they came from. I put it on this diamond stone and managed to grind away the chipped area. I then finished it on my 1000 and 6000 grit waterstones. Not only is this DMT diamond stone able to repair my friend's damaged household knife, it also matches Shun's VG-10 core knife. *Updated 03/02/2010 Coarse with plastic box for reprofiling knives. Extra coarse stone makes reprofiling the knife edge/bevels easier. However, for regular knife maintenance this fine DMT stone is probably better suited.*Update 08 June 2010*I have my Japanese one Woodstock water stone removed for a few months due to severe wear. I have since bought Naniwa Super Waterstones as a replacement. However, I still use DMT diamond stone and it is part of my setup. It seems to work. *Updated April 08, 2012 *Sorry for not updating sooner but the diamond stone started to wear at the corners in late 2010 or early 2011.
