Kazak M5 Sharpening System

Device intended for sharpening knives of various shapes and sizes. It enables stable clamping of the knife in the jaws and rotating it without removing it, ensuring high precision and a repeatable sharpening angle.

The Kazak M5 model was developed for both beginners and more advanced users involved in knife sharpening. The refined design allows control during work and makes it easier to achieve a uniform cutting edge without the need for specialist skills.

The base is made of 8 mm thick steel. The material ensures rigidity of the structure while guiding the sharpening stone along the blade. The surface is protected with a durable powder coating in black, which protects the steel against corrosion and damage resulting from regular use.

On the underside there are rubber inserts that increase the system's grip on the worktop and reduce movement of the device during sharpening. The stable base makes it easier to maintain a repeatable motion and control the pressure of the sharpening stone.

The vertical mast is made of structural steel with a diameter of 10 mm. The increased cross-section improves the rigidity of the system and reduces deflection during guide rod operation. The mast is coated with a protective coating, which protects its surface and ensures smooth movement of the adjustment components. The guide rod carriage can be moved along the column, adjusting the working height to the width and geometry of the blade.

The guide rod is also made of structural steel with a protective coating, and its length together with the handle is 450 mm. The sliding unit is made of polyacetal plastic. The material is characterized by a low coefficient of friction, wear resistance, and dimensional stability.

The knife is mounted using Krab-type clamps. Their design allows both short and long blades to be stabilized. The clamps are made by milling from solid 7075 aircraft-grade aluminum, valued for its high mechanical strength and low weight.

The clamping elements were designed to provide flexibility during opening and rigidity after the blade is secured. Once mounted, the blade remains stationary while the sharpening stone is moved. This limits changes to the set angle and makes it easier to achieve a repeatable result along the entire length of the cutting edge.

The system is adapted for sharpening knives with:

• maximum blade length 200 mm
• maximum blade thickness 5 mm

The sharpening angle is adjusted by changing the position of the carriage on the vertical mast. This makes it possible to match the setting to the type of knife, blade thickness, and expected cutting edge profile. For a knife width of 25 mm, the sharpening angle range on one side covers a minimum of 11 deg., and a maximum of 25 deg. The adjustment allows work with both more delicate kitchen blades and knives requiring a more durable working edge.

The system is equipped with a rotating mechanism based on a double-row ball bearing. It allows the knife to be turned to the other side without removing the blade from the clamps. This solution reduces the risk of changing the knife position between successive stages of work. It also makes it easier to maintain sharpening symmetry, because the blade remains mounted in the same arrangement.

The set includes an electronic protractor with batteries. The device makes it possible to monitor the set sharpening angle and helps match the parameters to a specific blade. Thanks to electronic measurement, the user does not have to rely solely on visual assessment. This is important when sharpening several knives with similar geometry and when reproducing a previously established edge profile.

The set also includes 2 diamond sharpening stones:

• grit 240
• grit 600

The 240 grit sharpening stone is used for more intensive material removal, edge correction, and work on a more dulled blade. 600 grit allows moving on to finer finishing and smoothing of the edge after the previous stage.

The system design allows the sharpening stone to be guided in a controlled and repeatable manner. Stable blade mounting, adjustable angle, and smooth guide rod movement reduce accidental deviations during sharpening.

The removable frame allows the cutting edge to be checked during work. It makes it possible to observe sharpening progress, check the evenness of the sharpening stone's contact with the blade, and detect any irregularities more quickly.

The system elements were designed to reduce play and maintain smooth operation. The sliding unit is characterized by increased smoothness of operation and durability estimated at up to 10 000 sharpening cycles.
