Forge Steel Diamond Sharpening Stone Coarse is rated 4.7 out of 5 by 21.
Rated 5 out of 5 by from Most useful toolbox addition Superb value, takes up very little space and is so thin you can sharpen things like countersink bits, which I have never done before, saved me buying a new one!!

Rated 5 out of 5 by from Great tool for the price I bought this to help remove the chips and damage from my kitchen knives, before using a whetstone. This is a fantastic tool and i would definitely recommend it. My only advice is make sure you dry it very thoroughly after use, as it will start to rust over very quickly if not, as i found out. Still, worth 5 stars in most categories.

Rated 4 out of 5 by from Sharpening made easy Sharpening chisels and plane blades can be a tedious process, whilst browsing the website i saw this product, it is inexpensive so i bought one to give it a whirl. I was surprised how quick it removed the material from the blades, speeding up the sharpening process no end. Remains to be seen how long it will last, however the initial results are very good.

Rated 4 out of 5 by from Fast course sharpener Good product, course grit means fast sharpening. Sliced through some very persistent glue stained chisels which had been much neglected and smoothed our a plane which had been badly damaged so that it had a ragged edge with big chunks missing. Took a while but did a nice job. Between the product and small steal shavings it's starting to rust in but still effective and for this price you can't complain.

Rated 4 out of 5 by from sharp Great for sharpening chisels and planer blades on site. Mounting onto a piece of board that can be clamped to a workbench helps make it easier to use.
