***Flattening a water / oil stone : One of the greatest drawbacks of these stones is that they do not stay true. The advantages of a diamond stone is speed of cut, flatness over time and longevity.

Draw multiple pencil lines on the waterstone, place the diamond stone 180 upwards on the non-slip mat, apply plenty of lapping fluid to the surface and then begin to rub the waterstone (with minimal pressure- the weight of the waterstone only) forward and backwards. After a few monents lift the waterstone and see if the bottom is completely precision flat. You will notice the pencil marks have completely disappeared. If they have not repeat the process until flattening is complete. The whole process should take no more than a couple of minutes. On completion add more lapping fluid to the surface of the diamond stone and rub clean with a cloth, then give the surface a thorough clean with the cleaning block.

The surface will be as good as new.
