TSPROF K4 Sharpening System

TSPROF K4 is engineered for those seeking the highest precision in knife sharpening. The system combines advanced mechanics with ease of use. Key features include:

• Three‐stage angle adjustment:
  1. Rough adjustment (±1° accuracy) via an extendable slider.
  2. Fine adjustment (±0.1°) using rack & pinion mechanism.
  3. Ultra‐fine micro adjustment (±0.01°) ideal for finishing & fine abrasives.
• Angle range from 9° to 39.5° per side, accommodates large blades (up to 430 mm / ~17") in length.
• Strong and stable structure: stainless steel + brass moving parts; robust base, designed for minimal deflection even under load.
• Tool includes a thickness compensator for switching abrasives without losing the angle setting.

• TSPROF К4 body with integrated base
• TSPROF abrasive holder with detachable electronic angle finder Axicube Shift
• TSPROF Quick clamps, black - 2 pcs.
• Spare parts
• Packaging: hard case with a foam insert

• Turning mechanism: Allows only 0.1° of arm deflection at a force of 30N. Ability to fully lock the flip will be useful during the reprofiling of the knife when it is subjected to heavy loads and vibrations, as well as when sharpening particularly long blades, when additional protection against accidental flipping is needed.
• Three-stage angle adjustment:
  - rough adjustment (accuracy up to 1°) with an extendable slider;
  - fine adjustment (up to 0.1°) with a rack and pinion mechanism;
  - ultra-fine adjustment (up to 0.01°) with the micro-adjustment unit.
• The arrangement of the sharpening system parts allows you to set the sharpening angle in the range from 9° to 39.5° per side, for knives up to 430 mm in length.
• Thickness compensator: Height adjuster is equipped with a removable stone thickness compensator. It provides a quick adjustment of the angle during stone change.
• Abrasive holder: Provides increased mounting security and ensures immobility of the elements during operation. Instead of point locking with a screw, the mechanism now uses surface locking through cylindrical sleeves with holes. This reduces the force required to secure the elements and eliminates the possibility of the rod surface damage.
• Rod parking: K4 carries over the stroke limiter and L-shaped piece from the K03, while introducing an upgraded parking system.
• New detachable Axicube Shift: Axicube Shift sits on the far abrasive stop. It can be quickly and easily removed to reduce abrasive weight during sharpening and for easy charging away from the sharpening system. The new mounting, featuring a special rail in combination with a locking screw and a magnet, provides an easy and secure attachment of the angle finder for accurate measurement of the sharpening angle. Axicube-i can be charged via USB Type-C cable.
• Quick clamps: Can securely hold knives up to 7 mm thick. They provide a fast and tool-free usage and a 300 N clamping force. Designed with finite element analysis, the clamps' structure evenly distributes stress for uniform jaw closure.
• Removable clamping arm: The new removable design of the clamping arm will become your favorite feature of the K4. No need to take the knife out of the clamps or try and repeat its position and set the same sharpening angle anymore.
• Rigid body and stable base: It attaches to the milled base with three rigid quick-release screws. Thanks to its shape, weight, and wide, slim shock absorbers, the system remains stable during sharpening.
