About DMT FWFC DuoSharp Double-Sided Diamond Sharpening Stone
Overall Feedback:
78% positive
74% found it easy to use
The sharpening-stone is fast, easy to use and requires no special preparation.
73% found it versatile
The sharpening-stones are versatile for field use due to their great difference in grits, but not ideal for home sharpening.
The sharpener has two sides - one for very dull knives and lawn mower blades, and the other for general light knife sharpening.
I suggest using a sharpening stone with fine/very fine grits for versatile and long-lasting sharpening.
64% highlighted the size and dimensions, but 36% didn't.
I had an issue with the sharpening-stones due to their small surface and soft mesh.
I find it difficult to sharpen anything but the shortest paring knife with the diamond-impregnated stone, as it is only about 5 inches long.
70% were satisfied with the grit size, but 30% faced issues
The coarse grit size is very aggressive. I don't own a knife that would need this grit. It's useful for reprofiling edge geometry or getting an abused knife back into decent shape. It can be used instead of a file for an axe or machete but would be slower.
I find that the extra fine grit size is good for achieving a polished finish on a blade, but it removes metal slowly.
Touching up the edge on the coarse side (325 grit) kept my knife running beautifully to the end of a long night.
The grit size of sharpening-stones was not enough to sharpen my knife. It scraped all the diamond grit off of the blue side, leaving it slick and useless.
75% appreciated the durability
I have used this sharpener for a year and it has held up well. I have bought several diamond stones over the years and have not faced any problems with this product. Based on my experience, this sharpener is durable.
