The TSPROF K03 PRO - precision-guided knife sharpening system. Become a knife sharpening professional with TSPROF K03. Keep all your knives razor-sharp, sharpen for friends, make money on knife sharpening or, if you make knives, take their sharpness to the next grade.
Sharpening is all about the consistency of the angle. We make the TSPROF K03 of CNC machined metal. Engineers look strictly at tolerance compliance, each unit passes quality control. The same level of high-precision machining is used in microscopes or the modern machine tool industry.
A knife flips over from 5 to 100 times per sharpening. Flip the knife in 1 second with the TSPROF K03 rotary mechanism. Fixation is automatic, with no screws or handles.
We designed clamps for ordinary and non-standard blades: kitchen, EDC, hunting, filet knife, machete, ax, planer knife, scissors, chisel, fully flat, convex grind knife, machete, and others.

Sharpen knives with any abrasive you like, the K03 universal abrasive holder supports all stones from 150 up to 200mm long and doesn’t require a 45° bevel on the sides.
Set any angle you want in 5 seconds using just 1 handle. Use a mechanical angle scale or digital protractor to see the angle instantly and precisely.
The sharpener is built over the modular concept. Get the sharpener’s body and extend it with additional clamps, abrasives, and accessories.

Modification of the TSPROF K03 body Rack-and-pinion lift with step adjustment allows you to set the angle with an accuracy of 0.05°. The range of sharpening angles is from 7° to 39°, which allows you to sharpen knives at a total angle of up to 78°.

The movable part is connected to the base with a dovetail joint, which guarantees the accuracy of setting the angle up to 0.05° an additional locking screw will allow you to lock the lift during grinding operations.

The rotary mechanism is made of hardened steel.

Whole-milled clamps are made of high-strength aircraft aluminum. Due to the monolithic design of the clamps, their main advantage is the increased resistance to pressure on the abrasive stone, which ensures constant angles. When working with this type of clamp, calibration, and adjustment to different knife shapes are not required.

The 3.5 kg TSPROF steel base holds the sharpener on the table and allows you to work without attaching the sharpening system body with a G-clamp.

The Axicube one allows you to determine the angle with an accuracy of 0.1° and helps to control the angle during the sharpening process when the frame is flipped over when changing the abrasive stone or sharpening the knife.


Universal attachment for the convex edge Pro 4.3 °, 7.2 °, and 10.7 for K03 is presented in the form of a replaceable adapter, which is mounted on the abrasive holder.
The convex edge is better than a V-shaped one to withstand shock loads, such as when cutting reeds, coastal shrubs, grass, large raw bones, and dead branches. Lenticular sharpening is more effective for deep cutting compared to knives with V-shaped sharpening, provided that the blade thickness is similar - this is due to less 'sticking' to the material. This form is most suitable for long-bladed combat weapons, large knives, and logging axes.

A set of abrasive stones Boride T2 series allows you to immediately start sharpening. The set includes 5 abrasive stones on aluminum blanks. Sharpening stones Boride T2 series are universal stones made of aluminum oxide, which are suitable for sharpening most steel grades. The set of sharpening stones Boride T2 series contains abrasives of various grain sizes: from 120 to 1200 grit. They work with oil lubricants. This set will be enough for all types of work, from grinding to final polishing.

A set of double-sided Premium diamond stones made by Venev Industrial Diamond Inc. on an aluminum blank. Manufactured on B2-01 organic bond and improved OSB organic bond. The organic bond consists of phenol-formaldehyde resins and various compositions based on them. Which, when hot pressed, are bakelite into a solid and sufficiently strong substance that holds the abrasive grains in the working layer of the tool. In this case, such a bond will be quite strong and vicious, but not rigid enough. To give it rigidity, abrasive grinding powders are added, such as boron carbide. The abrasive layer on this blank is not sintered but is glued to the blank body. Already out of the box, such a bar is ready to work, it does not require leveling on silicon carbide powder. The set includes:
Double-sided diamond stone Premium 160/125-100/80 100% - for rough and basic sharpening
Double-sided diamond stone Premium 50/40-20/14 100% - for basic sharpening
Double-sided diamond stone Premium 7/5-3/2 100% - for finishing polishing

A small universal table is a special clamp designed for sharpening scissors, ice drill blades, chisels, and other tools that are not installed in other clamps.

Dialux Blanc polishing compound supplied with a leather blank is used for the final polishing of the knife.

A case of the German company WAG with the TSPROF brand name, made of hard plastic, is used for carrying the K03 sharpening system.

Folding magnifier with 40x magnification to control the process of sharpening the cutting edge of the knife. It has a plastic body with a metal protective cover. The backlight of two white LEDs allows you to view the details of the cutting-edge condition and check the maintenance of the sharpening angle.
