Sharpening device TSPROF Profile K4

TSPROF K4 — an innovative knife sharpening system that combines advanced technology with unparalleled precision.

Pivot Mechanism

The force required to flip the clamp frame can be smoothly adjusted with a screw on the back cover of the pivot mechanism. A full locking feature is also available, which is useful for major blade re-profiling, during long grinding sessions when the blade is subject to high loads and vibrations, and when sharpening particularly long blades that require extra protection from accidental flipping. The scheme for fixing movable elements inside the assembly has been completely changed. This results in greater rigidity when holding the frame in the horizontal position, with the frame deviation under a force of 30 N being only 0.1°.

Rack-and-Pinion Lifter

Its design allows for easier, faster, and more precise angle setting. The movable elements of the lifter can be locked with one hand, providing reliable fixation at the set position. There are three ways to set the angle: coarse adjustment (with a precision of up to 1°) using the sliding carriage, fine adjustment (up to 0.1°) with the rack-and-pinion lifter, and ultra-fine adjustment (up to 0.01°) with the micro-feed mechanism. The micro-feed mechanism allows for angle changes with a precision of less than 0.1°, which is especially useful for burr removal and when working with particularly thin abrasives.

Compensator

A removable compensator for abrasive thickness difference is implemented on the rack-and-pinion lifter, allowing you to quickly hit the desired angle when changing stones.

Abrasive Holder

A fundamentally new method of fastening the limiters and the coupling on the guide rod ensures increased reliability and immobility of the elements during operation. Instead of point fixation with a screw, fixation is now achieved over an area, through cylindrical couplings with holes. The force required to fix the elements has been reduced, and the possibility of damaging the surface of the guide rod has been eliminated. The front stop of the guide rod allows for easy removal and installation of the abrasive stone. A screw with a spring-loaded ball installed in the stop limits its free rotation on the guide rod and ensures smoother movement. The pivot joint uses a stainless steel-brass sliding pair, ensuring smooth movement of the guide rod during operation.

Parking

Familiar to TSPROF K03 users, the parking feature using a limiter and a brake disc has undergone minor changes in its kinematic scheme and has become even more convenient.

Quick-Release Electronic Angle Gauge Axicube-i with Removable Battery

The angle gauge is located on the far stop of the guide rod, with the ability to be quickly installed and removed to reduce the load on the abrasive during work and for convenient charging away from the sharpening system. The picatinny rail mount, combined with a set screw and magnet, ensures easy and reliable fixation of the angle gauge for precise sharpening angle measurements. The device is charged via a USB type-C connector.

Quick Clamps

The TSPROF Quick eccentric clamp allows for reliable clamping of knives with a thickness from 1 to 7 mm. It provides a fast and easy way to clamp a knife with a force of 300 N without the use of screwdrivers. The design of the TSPROF clamps has been stress-analyzed using the finite element method. The material thickness and structural elements are calculated so that stresses are evenly distributed along the entire length of the clamp, ensuring uniform closure of the jaws during clamping.

Removable Frame

You can remove the knife, without taking it out of the clamps, at any stage of sharpening. You can check the condition of the cutting edge and return the knife to its original position in the sharpening system. There is no need to re-set the sharpening angle, re-position the knife in the clamps, or hit the bevel again. The frame is compatible with all clamps of the TSPROF K03, TSPROF Kadet, and TSPROF Pioneer sharpening systems.

More Sharpening Options for Various Knives

The layout of the sharpening system’s components allows for setting a sharpening angle per side in the range of 9° to 39.5° for knives up to 430 mm long.

Robust Construction and Stable Base

The stand’s design not only features an updated look but also provides convenience for carrying the product, allowing you to comfortably hold the device with one hand. The system is attached to a milled base with three quick-release fasteners, which securely fix the system’s stand to a steel plate. Thanks to its shape, weight, and thin, wide shock absorbers, the system will remain stationary on this base during sharpening.
