The Atoma Tsuboman Diamond Sharpening Plate #400 is a professional tool for flattening sharpening stones and precisely sharpening knives, chisels, and razors. The #400 grit provides the perfect balance between effective material removal and a smooth finish on the blade. Thanks to the use of monocrystalline diamonds, the plate is highly durable and does not deform during use.
The #400 grit abrasive surface is ideal for flattening sharpening stones, which is crucial for maintaining their sharpening effectiveness. It is also suitable for precise grinding of blades, removing minor damage, and improving cutting edges. The high quality of the diamond coating allows you to work with even the hardest powder steels, such as ZDP-189, HAP-40, and R2.
Thanks to the electrolytic diamond bonding process, the abrasive is extremely durable and evenly distributed across the surface of the plate. The design, based on a solid aluminum base, ensures stability and comfort of use. The replaceable abrasive layer allows for long-term use without the need to purchase a new plate.
The Atoma Tsuboman Diamond Sharpening Plate #400 is an excellent choice for professionals and enthusiasts who require precision and efficiency in the sharpening process. It is indispensable for flattening sharpening stones, grinding, and maintaining blades.
