DMT WM8EF DuoSharp Sharpening stone Review

For a sharpening stone that will never let you down, go for DMT WM8EF DuoSharp

This DuoSharp Bench Stone knife sharpener offers excellent and fast sharpening of a variety of knives and edge types, as well as some small tools as well.


The sharpener features two diamond fines which ensure much faster sharpening than when using conventional sharpening stones. The knife sharpener provides two-step sharpening – the first with a fine diamond for razor sharp sharpening of blades and the second – an extra-fine for polishing and refining the knife’s edge.

The actual sharpening is done either with water or dry. No oil is required, which means that the sharpening is fast and doesn’t create a mess.

This sharpening bench is of very high quality and is sturdy and durable enough to last for years and sharpen your knives for a long time.

The producer of this great sharpener claims that the diamonds sharpening tools can remove metal and sharpen a blade 10 times faster than conventional stone sharpeners, and we tend to believe him.


Once you find the right angle, it is very easy to use. Very little pressure or effort is required for the sharpening.

A dull knife or other tool will be perfectly sharpened for no more than 3 minutes, and a refreshing sharpening of an already sharp blade will take about a minute. So, this bench stone allows for fast and efficient sharpening. It has a stable base which keeps the diamond fines in place during the sharpening process. Plus, the base has rubber feet for added stability and support during the sharpening process.

This wonderful product comes with an unconditional warrantee, so if there is a defect or problem in yours, it will be replaced free of charge.


It is costlier than the conventional sharpening benches, but given the quality, the ease of use and the fast and highly efficient sharpening it offers, it is definitely an investment worthwhile.

You can be sure that you will be using this sharpening bench for years to come, and it will never let you down.
