The KMFS SENSEI sharpening system is a completely new type of set.
The KMFS SENSEI allows you to maintain a precise sharpening angle when using any type of whetstone, while working completely hands-free, thereby achieving perfect results with maximum sharpening performance.
The patented grinding system was developed and manufactured entirely in the Czech Republic.
This grinding system utilizes our patented reverse kinematics, ensuring a consistent angle across the entire edge of the sharpened blade.
The set is equipped with a stainless steel hover spring, which is adjusted via the adjustment wheel on the rod to enable optimal sharpening on stones of varying thicknesses or with different blade heights.
The set allows you to choose the position of the kinematics with the rod in the center or on the left/right to ensure optimal movement of the kinematics for various sharpening styles.
The sharpening system in the basic set includes a head with sharpening angles of 15°, 17.5°, 20°, and 22.5°, which are maintained with absolute precision across the entire blade and during every sharpening operation. Additional accessories in the set also allow for sharpening at other angles. Note: This refers to the angle between the clamping magnets and the sharpening stone.
Thanks to the strong dual magnetic mounting, the blade can be clamped in place very quickly and securely. The magnets are encased in a protective rubber sleeve that improves grip and protects the blade’s surface.
A stand made entirely of stainless steel, which not only serves as a counterweight but also effectively dampens vibrations, ensures solid and stable sharpening.
The set is fully equipped with ball bearings that ensure absolutely smooth operation without play. There are 4 fully enclosed bearings for rotation around two angular axes and 3 double four-row linear bearings for linear movements.
The set features a stainless steel whetstone holder that can accommodate all KMFS stones and most stones from other manufacturers. Since there are no issues with the transition of the abrasive, the set does not need to be adjusted in any way for different abrasive thicknesses; the kinematics always ensure the correct angle. The set also allows for the use of any diamond or water-cooled grinding stones up to a length of 225 mm.
