desertcart.co.jp: dia-sharp XX Coarse Grit : DIY, Tools & Garden Review: The dmt mef is scratchy to use even with lube, and he scratch pattern is harsher than the sharpal 1200. It will produce a burr and a sharp edge. After using it further I believe it has quite alot of grit contamination and would return it if possible..... Review: I've been using DMT products since the '80s. These Dia-Sharp 8" are my mainstays. Once broken in, they grade fairly and just don't require the maintenance of other stones. If you have the range (after the Medium-Extra-Fine I have them all) you can tackle anything. The 4000 (6 micron) has been a hole in this line for a while, it's nice to see it has been filled. As delivered, these stones have a lot of manufacturing "gunk" on them, and when new can be pretty sharp, i.e. grading lower (coarser) than marked. The stones break-in with use, and I actually break them in before using on anything of any significance. To break these stones in and clean them up, spray with 50/50 solution of Simple Green and Water. Use this as a lube for the stones all the time, it just works better than water or dry. Take a hardened piece (nice if it is the width of the stone) of 440C (I use a old knife tang) and run it up and down the stone, in circles or whatever, but try to cover the whole area. Keep adding Simple Green as needed, wipe the stone and steel off when it gets dirty (it will) and you should start to feel the stone smoothing out. There are little pieces of dirt and manufacturing eccentricities in the coating they put on them and you need to work that off. Once that is off, the stone will exhibit a much more uniform texture that you would expect. At the point that the surface is uniform, the stone will still grade a little rough, but will smooth out with use. Keep using the Simple Green solution to keep the stone and work clean. When breaking-in, pay significant attention to working the edges of the stone, this is important as this area can be a little rough. Even using the Dia-Lap 120 to chamfer the edges doesn't work all that well. If you are lucky enough to have a stone that they didn't get coated all the way to the edges, don't send it back; I wish they made them all that way. The stone should exhibit a uniform gray/silver appearance when properly cleaned and broken-in.

En verdad estas placas diamantadas son una maravilla, ayudan enormemente en el afilado de las cuchillas y formones. Por fin mis herramientas están con el filo adecuado, al usarlas se nota la diferencia. Esta placa la uso para pasar a una piedra de agua más fina, pero si no tuviera la piedra, bastaría solo asentar el filo un poco y a cortar.
