Atoma diamond sharpening plate, coarse, 140 grit

Atoma Economy diamond sharpening plates Often the label "economy" makes one suspicious that the manufacturer may have skimped on the quality of the materials he used for his tools. That is not the case here. Instead it has to do with the manufacturing process. Originally thick aluminum or steel plates were coated with diamond chips. This is expensive and the plates were very sensitive to mishandling. Tsuboman therefore decided to make the plates in this product line out of 1 mm thick stainless steel coated with diamonds and then used a double-sided adhesive tape to fix the plate to a 10 mm thick flat-machined aluminum plate. This product is relatively easy to manufacture, and when the diamond plate is worn out, you only have to buy a new one and glue it to the re-useable baseplate. It also makes for a lighter stone, 600 grams rather than 1000 grams of the original solid steel plate, a real weight saving. This method also makes for an unusually flat surface compared with other similarly priced stones. We placed a number of these plates on a certified flat granite measuring stone, and a 0.04 mm feeler gauge would not fit under the sharpening plate. We cannot guarantee this level of flatness for every Atoma plate we sell, but we can say that they are in general astonishingly flat. Sharpening surface 210 x 75 mm Total thickness 11.4 mm
