I have the DMT diamond stones 8″ x 3″ Fine Medium and course I have had them for nearly 4 year and they are still working well. The flattening of chisel backs and irons is best done using sandpaper on flat glass, not only is it quicker but will ensure your diamond stones last longer for sharpening.
I would not hesitate to buy them again
Thanks David. I started woodworking about a year and a half ago. The first 600 grit stone I bought was cheap, and is starting to come apart. I was hoping to avoid the same fate with a more expensive plate.
Thank you for the tip as well. I am a commercial glazier by trade. I use a 12 inch square piece of 1/2 inch thick glass with wet or dry sandpaper glued to it to flatten new blades. Works great 🙂
I’ve used the DMT coarse and extra-fine stones for several years, recently added the fine (600) to the mix. Very happy with all, especially the ease of prep and use. The three water stones now sit unused.
