Attention due to the economic situation in the United States, namely the increase in duties on imports of over-precise parts from the EU and Ukraine, as well as the increase in fuel and logistics prices, prices for products have been increasing since May 2026. Shipping prices will also increase from April 1 by 15% for all logistics companies in the United States. Sincerely, KAZAK USA LLC / Pocatello Sharpening Service

Stone Boride 900F on aluminum base
900-F Grit 900; Dimensions: 152 x 25 x 6
Suitable for finishing sharpening of hard steel
Work with oil
 
This stone has super-fine structure and excellent breakdown properties for final finishing prior to mirror (diamond polished) finishing. The 900-F works especially well on P-20 mold steel with a hardness ranging from 29 to 32Rc. The 900-F is primarily used for hand finishing operations. Always use a lubricant with the stone.
The soft bond of the Boride 900-F bar allows it to cope well with fairly hard steels of 58-62 units. Therefore, this stone can be safely recommended for the widest range of blades in terms of hardness of steels from the softest stainless steel to very hard high-alloy steels with a high carbon content.
All stones are 6 mm thick and are mounted on high-quality aluminum blanks.
