The Atoma Tsuboman Diamond Sharpening Plate #140 is a professional tool for aggressive material removal, ideal for both repairing damaged blades and flattening sharpening stones. Thanks to the use of monocrystalline diamonds, the plate offers exceptional durability and effectiveness, and the replaceable abrasive layer ensures a long service life.
The #140 grit abrasive surface allows for quick and effective removal of irregularities and changes in blade geometry. It is perfect for sharpening hard powder steels such as ZDP-189, HAP-40, and R2, which can be challenging for standard sharpening stones. Thanks to the electrolytic diamond bonding process, the plate retains its performance for a long time and does not wear out as quickly as traditional abrasives.
The base is made of high-quality aluminum, ensuring stability and comfort of use. The design of the plate allows for even sharpening, which is crucial for achieving precise cutting edges. Thanks to the replaceable abrasive layer, the user can easily extend the life of the product without having to buy a new plate.
The Atoma Tsuboman Diamond Sharpening Plate #140 is an indispensable tool for professionals and sharpening enthusiasts, guaranteeing precise, fast, and effective sharpening of even the most demanding steels.
