The M.Power Diamond Cross 8" benchstone, double-sided with 600 and 1200 grit. The stone is a laminated hybrid combining the advantages of stainless steel and O1 tool steel.
The monocrystalline diamond plates are made of high quality rust-proof stainless steel. At the core is a precision ground tool steel plate that provides the basis for an ultra flat diamond surface, with a finished tolerance of +/- 0.00175" (0.044 mm) across the entire length. The laminate is pressure bonded using a high specification 3M adhesive.
The result is a stone offering the performance and flatness of far more expensive stones, backed with a 3 year guarantee.

A water stone wears unevenly and becomes dished in the middle over time. That makes it hard to get a straight edge, so the stone needs flattening regularly, ideally every time you have sharpened for a while.
The easiest way is to rub the surface of the stone against a coarse diamond stone under running water until it is flat. Draw a pencil grid on the stone first, so you can see when it has all been removed. You can also use the diamond stone to sharpen tools when you need a coarser grit than 300.
Diamond stones usually come in 180, 300/360, 600 and 1000/1200 grit. The labels correspond roughly to:
Fine: about 600 grit
Extra fine: about 1000/1200 grit
If you will be sharpening plane blades, choose diamond stones that are 210 mm (8") long, so there is room for wider blades and you get an even result.
There are several good ways to sharpen chisels and plane irons: water stones, diamond stones, oil stones and sharpening machines such as Tormek. All give sharp edges, but they differ in speed, maintenance and price.
A honing guide makes it easier to keep the same angle every time. The most important thing is to find a method you enjoy and use often. The guide helps you choose.
Which water stone you need depends on how dull your edges are and how fine a finish you want. A common setup is a coarse stone around 1000 grit to shape the edge and a fine stone around 5000–8000 grit to polish it. For chipped edges you need a coarser stone too.
Water stones wear unevenly and need flattening regularly. The guide explains grits, brands and flattening.
