Fantastic.
An absolute brilliant piece of kit,sharpened all of my chisels and plane blades in half the time and with an infinitely better finish than I used to get using an oil stone. Money well spent!!

Easy to use, high quality stones
My first set of diamond sharpening stones and all I can say is I'm very impressed! They are so easy to use and sharpen my kitchen knives in half the time of traditional stones. One thing I would say is they feel a bit plasticky and when you use them you can only have one stone in the box. That said, great stones and brilliant quality.

Have had one of these stones for 14 years and it is still going
Good set of stones with a proven track record on quality ,but do not keep the stones in the box when you are adding water or oil , or the box will start warping remove and use on your bench

Quicker and flatter than a stone
Excellent for sharpening handtools. Quicker than a stone and does not need flattening.
