A multifaceted diamond sharpening stone
Quad Diamond Sharpening Stone Here's a handy and very practical product, good quality on sharpening. The quad diamond sharpening stone comes with four grades of diamond grit with color coded panels: Blue=extra coarse (200 grit)-Yellow= coarse (300 grit) - Green= medium (400 grit)-Red= fine (600 grit). Some of the features of this product: Ideal for chisels, plane blades, knives, shears etc. You can change the grit value of the working surface easily and quickly... How? Simply lift the sharpening block from the base, rotate so that the desired working surface is facing upwards and then re-insert into the base. The block base is fitted with a pair of worksafe surface-gripping feet. I started with sharpening chisels using all the grades and I am very happy with the result. In my opinion, quick and effortless sharpening but with some practicing it will all be better!

Relatively well made, performs as it should do.
It feels a little bit cheap, but it does exactly what it needs to. I've had no problems with mine and it sharpens my knives very nicely. The different grades work well and it's simple to turn the box around and start fine tuning the blade.

Works a Treat
Used this on various knives, chisels etc and so far it works fine. The course grit really bites into the tool and is probably best used on gardening equipment. The fine grit sharpens knives and alike in shirt time to a nice edge. Only issue is the box which slide about as is has no weight but some suck on rubber feet might solve this.

Diamond Sharpening Stone 4-Sided
Nice tool and easy to use, it sharpened my abused chisels nicely. The only gripe I have [small one] is I had to fix a temporary stop block to my bench to stop it going "walkies". Otherwise well worth the money. P/S I recommend a drop of WD40 on the chisel area to be sharpened.

Great for getting a sharp edge on my blade.

Colis arrivé en parfait état mais je comprends que certains aient eux des problèmes... Aucun emballage de protection pour un produit qui est fragile, c'est un peu la loterie du coup.
