DMT WM8EF-WB 8-Inch Extra Fine/Fine DuoSharp Plus Bench Stone with Base - Grey

In my opinion DMT are the best you can get. Tried others and they didn't last. I have several of their product's and this fine/very fine stone allows me to put a razor sharp edge on my chisels, plane blades, etc. The continuous diamond allows me to sharpen my 1/8" chisels and other small items. Quality kit.

great price and quality

Requires just a little bit of practice

Certainly puts an edge on my knives Time will tell as to how long it lasts but I use it with water so that should help

Very effective sharpening system.

Great product! With help from training videos the Duo Sharp Plus has proved easy to use and incredibly effective. Thanks DMT...

The "stone" is a plastic strip covered in metal grill. It works as advertised, but my main issue with this item is the very poor quality plastic holder that comes with it. There are 2 removable plastic retainers that were delivered bent out of shape probably due to moulding issues. This is a quality control issue. I will have to permanently glue the one side in place and just hope that the other side stays working. Eventually I will need to look for an alternative method of holding the "stone" in place whilst using. I bought a cheap alternative to compare it with, and whilst the cheaper stone does not work as well as this, the method of holding it in place is far better engineered. DMT should look at a better holder if they are going to charge so much. Very disappointed overall.

Great product. Are stones acting of the past?

Ich bin zufrieden, kann damit wirklich alles schärfen von küchenwerkzeug bis schindelaxt. Vor allem wenn man hochrechnet dass der 2 Seiten hat mit viel mehr schleiffläche finde ich den tatsächlich besser als das 3er set

Comprem, será o melhor produto que já imaginaram possuir para afiar suas facas ou equipamentos. É o segundo que compro. Agora tenho às granulometrias que necessitava.

The DMT WM8EF-WB 8-Inch DuoSharp Plus Bench Stone (Extra Fine/Fine With Base) is an outstanding value at $55. While some might find that price to be high, keep in mind that you're getting a large 3" x 8" double-sided diamond sharpener (one side is fine 600-grit for all around sharpening, the other is extra fine 1200-grit for getting your blades to a razor sharp edge). Unlike natural stones, the polymer base also won't deform. It stays perfectly flat over time. And the sharpening goes MUCH faster. 10 swipes on this stone is roughly equivalent to about 50 swipes on an Arkansas stone. Not only do you save time and energy, but it's much easier to maintain a very consistent blade angle (crucial to effective sharpening) for 10 strokes than it is for 50. This model includes the robust plastic base as well. The stone snaps into the base very snugly (no looseness) and the wide feet provide for a very stable platform while sharpening. For added security, you can fasten the base to a workbench or other large surface. However, I found the base stable enough on its own to be perfectly serviceable on a kitchen countertop. It would be nice if the base had grippy rubberized feet to reduce slippage on smooth surfaces for those like me who don't want to permanently affix it to a workbench, but if you brace one end of the base against something (such as the edge of the sink or the stove) and draw the knife in that direction, it works fine and won't slip. I've used this stone to sharpen everything from my smallest Swiss Army blade (2" stainless) up to my Ka-Bar/Becker BK7 blade (7" 1095 cro-van steel). Sharpening a large 7" knife on this stone is very easy. The general rule of thumb is that your stone should be at least as long as your blade, so if you have knife blades longer than 8", you may want to spend more for the 10-inch version of this stone (which at the time of this review, is inexplicably listed at nearly three times the price!?). For my needs, the 8 inch stone is plenty long. There's nothing to complain about with regard to the quality and functionality of this product. It's first rate and will do a very good job sharpening your knives, assuming you take time to learn the proper technique. Throw in an old belt with sharpening compound for stropping, and you will have the tools to put a scary sharp edge on most any knife. The only shortcoming I notice with this product is the ambiguity of the stone in determining which side is fine (600-grit) and which extra fine (1200-grit). As it turns out, it is color coded by a small circle at one end of the stone, which then can be cross-compared with a list on the packaging to determine the grit. But it's strange to me that they didn't just stamp "600-grit" and "1200-grit" on the respective sides instead of the color-coding--which would be clearer and more convenient. I simply wrote the proper grit (with an appropriately pointed arrow) on either side of the stone in permanent black ink. Technically, you can tell by feel as well. Regardless, some people are sure to be inexperienced and inadvertently use the extra fine side to initially sharpen a very dull blade, and then will get dismayed by the slowness. The fine (600-grit) side will restore a fairly dull blade very quickly, however, and is probably the best "general purpose" grit for knives. For quick blade touch ups, you could skip using the extra fine side altogether unless you really need to get your blades shaving sharp or just enjoy bringing the edge up to a more polished look. All in all, this is a great product and well worth the price. Sure, natural stone sets with comparable grits can be had for half as much money, but they require more effort and care, and thus, introduce more room for error. This is your best bet for faster, superb sharpening results. If idiot-proof convenience is your priority, you may prefer a pull-through sharpener. However, keep in mind that those kind will not put nearly as nice or as long-lasting of an edge on your knives. They are convenient thought. In my opinion, a diamond stone like this one is the best way to do it right. [UPDATE 4-1-2014: I've been using this sharpener a lot for a month and a half now and it is the best diamond sharpener I've ever owned. It works very quickly on every blade and steel I've tried, and can take a blade from very dull to very sharp in only a few dozen strokes. The trick is to keep the sharpening angle consistent for each stroke (I sharpen at 21 degrees for wilderness knives, and about 17 degrees for kitchen knives), and apply the right amount of pressure as you stroke. Once you get a feel for it, this sharpener works superbly.]

1) Damaged box when it is received. 2) Rusty surfaces are found in multiple parts of the product.

Very good quality. I ordered two DMT bench stones providing me with 4 grits. Easier to sharpen knives with better results than the Angle guided systems I’ve tried with less fuss. I do use a little square that has four reference angles on it with these stones when I want to set a new angle on a knife. Diamond stones also make for less mess than oil stones with a little spray of water to sharpen and soap and water clean up. Now my technique is improving by leaps and bounds the more I’m sharpening but the learning curve was a I on t the same as the angle guided system I used and now I can sharpen anything! No size restrictions. Excellent product. The base is solid too.
