Matte Black Anodizing
New 2026
• The K4 stand and core components are now made from aircraft-grade aluminum with a matte black anodized finish.
• The anodized layer protects the metal from corrosion and minor damage, resists environmental exposure, and retains its color for years. The matte surface feels solid in hand and preserves the tool’s appearance throughout its service life.
Impact-resistant carrying case
New 2026
• All K4 units come in a protective TSPROF case with custom EVA inserts for each component.
• High-strength polyurethane body, secure latches, a rubber seal, and a pressure release valve under the handle.
Upgraded knife turning mechanism
The K4 is equipped with an upgraded knife flipping mechanism with adjustable tension. The mechanism can withstand 30 N before a deviation of 0.1° occurs. The full tension ensures protection against accidental activation of the turning mechanism during heavy-duty grinding and reprofiling operations.
Multi-level rack-and-pinion height adjuster
The K4 high-precision angle-adjustment mechanism allows easy and fast setting of the sharpening angle. All moving parts can be locked with just one hand. Three-level adjustment system prvoides maximum flexibility.
You are in control of the sharpening process
Micro-adjustment of the sharpening angle
Each click of the micro-adjustment ring adjusts the angle by 0.01°, delivering ultimate precision for deburring and working with the finest abrasives.
Axicube Shift
The new Axicube Shift model can be detached from the abrasive stopper and provides quick and convenient mounting of the angle finder, ensuring precise angle measurement.
TSPROF Quick clamps
These quick-release clamps provide strong clamping for knives between 1 and 7 mm thick, ensuring uniform jaw closure. Included as standard K4 clamps.
TSPROF K4 takes your sharpening to the next level

Guided by the wisdom of true experts, the K4 reaches new heights of precision
