These diamond-coated flexible steel sheets are incredibly versatile. They are ideal for making your own sharpening, honing, deburring, grinding, shaping or polishing tools. The sheets are 100mm wide and 200mm long, stainless steel, 0.4mm thick, diamond-coated on one side with a self-adhesive backing. You can cut the sheet with a pair of stout scissors or light snips into any shape you want. The self-adhesive backing is strong and easy to fix onto a flat or curved surface. They are available in a choice of grades: coarse 240grit, medium 400grit and fine 1,000grit. You can use these diamond sheets either wet or dry. Always allow the diamond abrasive to do the work; too much pressure is less efficient. Super-hard and durable, the diamond abrasive will cut or sharpen high carbon steels, tungsten, ceramics, glass and stone.

A £100 diamond plate for less than £20!! Not quite...Buying a 4" x 8" diamond plate by trend/ezelap/freud will cost you £80ish upwards. I saw these sheets in the Nuneaton store, and decided it was worth a punt to flatten the backs of my Narex chisels. I bought a 1/2" thick piece of 304 aluminium plate off eBay and flattened it by scraping it in on my surface plate. When the sheet was stuck down on the plate, everything looked perfectly flat and ready to go. At first the surface felt very sharp and fast-cutting, but after 15 mins of use, this subsided rapidly as I flattened more chisels. The upside was that the finish on the chisels improved markedly, but everything took longer and longer. Overall I am pleased with the end result, but in hindsight, I would use 400 and then 1000 grit sheets to compensate for the rapid initial deterioration of the cutting performance. I have not used very expensive diamond plates, but I assume they last longer. Not all diamonds are the same! These sheets give a vastly superior result to wet and dry paper, and will ultimately work out cheaper in the long run. The price was only £15 when I bought them, but they still seem cheap.
