I have to say I have enjoyed my purchase. The diamond stone is easy to use and gives great results when sharpening blunt knives. The coarse grit means there is not a lot of time to be spent in putting a decent edge on the blade. My only adverse remark would be, is that for larger blades, the size (6 in.) is perhaps a bit restricting, however for smaller blades it is definitely a winner.
