Atoma diamond sharpening stones

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

These are made to replace the cutting surfaces of the Atoma diamond sharpening plates described above. But they can also be glued down to other backing plates of your choice. The backs are covered with strips of double-sided adhesive tape and gluing them down is quick and easy. The plates are made of 1 mm thick stainless steel; with the tape the total thickness is 1.4 mm. Because the plates are so thin, you must take care when fixing them to a backing material; the quality of the result depends a great deal on the flatness and stiffness of the backing plate you choose!

Sharpening surface 210 x 75 mm

These are very flexible, self-adhesive plates made of a copper foil coated with diamond chips. The total thickness is only 0.5 mm. They can be glued to surfaces of almost any shape, and can also be cut, with suitable scissors, to any shape you desire. They are useful for many different types of metal work. If they are used to sharpen tools, like chisels or knives, you must be careful not to pierce the relatively fragile copper foil and damage the surface. Do not sharpen in the direction of the cutting edge or other sharp corners. The diamond coated foil comes in grit grades of 140 (coarse), 200 (semi-coarse), 400 (medium), 600 (fine), and 1200 (extra fine).

Note: We do not hold large quantities of foil plates in stock!
