In Detail

The 120 mesh extra-extra coarse surface removes stock quickly and precisely. With a surface flatness of ±0.02mm, diamond performance and durability, the Double X is perfect for flattening: Waterstones, Arkansas stones, and Synthetic stones. It will quickly flatten plane irons and chisel backs with little effort and will quickly remove edge nicks and chips. Precisely Micronised monocrystaline diamond is extremely durable. Use with water only, no oil required, the Double X will not chip, crack, hollow or groove as with conventional abrasive stones. The solid steel plate is 203 x 76 x 9.5mm thick, with a heavy plating of nickel to prevent corrosion.

Cost equals quality

It seems an expensive option but I bought this particular plate only for flattening waterstones. It works superbly, quickly flattening stones accurately which then produce the best possible edge and flat back. I also have two other DMT plates used for preparing plane frogs, initial work on blades and chisels, all are excellent
