Tools and Hardware Reviews of DMT W250EFNB 10-Inch DuoSharp Bench Stone Extra-Fine / Fine No Base
Customer Review: Stop the presses!
Summary: 5 Stars
I have used various stones for sharpening knives for (too) many years. In fact, I have reviewed two of them here on Amazon.com. I stand by my positive reviews of the stones, but this 4x10 diamond stone takes it all to a new level. I wanted to try the latest in whetstones, and this one caught my eye because it is LARGE, and has two grits built in. It is also very expensive. That being said, using this tool will leave you speechless. It is that good. First of all, it is large enough to handle anything from a penknife to a 10" slicer with full coverage in a single stroke. Every whetstone should be this size. It is also thin, and isn't consumed during sharpening. The non slip pad provided with the stone works like a charm. Water is the only lubricant used, and cleanup is a snap.
Don't be fooled by the "fine" and "extra fine" rating of it's surfaces. The fine side will fix a badly worn kitchen edge in a few strokes. My guess is that the knife will also be better than new when you are done. The extra fine side will turn good steel into a razor in just a few more strokes. After years of taking time and care to acheive a perfect edge with natural and man made stones, this was an epiphany. The job was so easy, and the results so fantastic, that I went on a sharpening binge and turned over 15 well used knives into razors in little more than 30 minutes.
I also bought the Global sharpening guides for a couple of bucks. They are not needed for small knives, or for an experienced pro, but they make the fine edge look very uniform on longer blades. They give the "factory" look with the custom edge.
This is an incredible tool. By the way, when you are done, you just rinse it and put it away. I doesn't get any better than this!
Customer Review: Very good sharpener
Summary: 5 Stars
This is a very good sharpening "stone" for not-completly dull knives, as the fine side will not remove much material. But a few strokes on the fine side and some more on the extra-fine side, you can get easy razor sharp edge.Customer Review: planes & chisel sharpening
Summary: 5 Stars
I purchased this item to sharpen woodworking planes and chisels. Good quality item. Works just as advertised. The larger size allows me to use a Veritas roller jig to keep the blade angle steady (although the jig is not worth the money for other reasons). Water wash off and easy cleaning. The plastic base is worth the extra money IMHO, but the antistick plastic mat works pretty well. I also used the "scary sharp" system to put a razor sharp edge on the blades. This is a automotive sandpaper on flat plate glass. The DMT fine whetstone is about a 15 micron equivalent where the "sandpaper" goes down to 0.5 micron. The chisel edge shines like a mirror.
My only disappointment was in flattening the backs of old chisels. A coarser grade of diamond is needed for this higher metal removal technique. I tried coarse grade sandpaper, but it wore out quickly. The finer sandpaper grades do not because they only recieve 5-10 strokes after the diamond stone.
For knives and general sharpening utensils, this diamond plate is great. For woodworking, I would buy the coarse / x-fine combination whetstone. Use the coarse side for the one time flattening and the fine or x-fine side for the intermediate surface grinding. Keep one 9"x12" glass plate of really fine micron sandpaper for the final polish.
