A four stack Nano Hone #200 Whetstone and Universal backing plate – this is a lovely coarse stone for fast removal of metal, suitable for repairing chips in blades or putting a first edge on a very blunt blade. All coarser stones wear a bit more quickly than finer grits and so Nano Hone has fused together four #200 stones - giving the life of four but at a fraction of the cost of buying them individually. 

The incredible consistency of those stones means they are much nicer and quieter to use than any other stone I have used of a comparable grit.

Nano Hone have incredibly precise production techniques, as indicated by their slogan "Our world is flat", and their whetstones and sharpening system is absolutely top notch.

Ideally use with the Nano Hone Stone Stage NH10, although with the aluminium backing plate, it can also be slotted into an Ito stone holder.
