About K03 PRO

TSPROF K03 Pro is an updated version of K03, the most famous Russian knife sharpener. TSProf is high-precision CNC machining, wear-resistant materials, the tightest tolerances, and strict quality control for each unit. K03 Pro will help you get a perfectly sharp edge of the blade even faster, more accurately, and with more convenience. 

Axicube-I - the first electronic angle finder designed specifically for sharpening systems. Setting an angle with an accuracy of 0.1° has never been easier or more convenient, the angle finder is built directly into the abrasive holder. The holder itself consists of two steel guiding rods. A coupling with a special shape ensures a rigid and precise connection. No deflection and maximum precision.

Pro Height Adjuster is equipped with a modern rack and pinion lift, which has a rail with involute (toothed) gearing and fine adjustment, allowing you to set the angle with an accuracy of 0.1°. The height adjuster with an extended angle, due to its improved design, will allow you to sharpen knives in a range of angles from 8° to 39°, which allows you to sharpen to a total angle of up to 78°.

The movable part is connected to the base with a dovetail, which guarantees absolute accuracy of angle setting. An additional locking screw allows the lift to be rigidly locked during deburring operations. An additional lifting rod is used to increase the angle of sharpening. Fixing its position is now more convenient: the fixing screw can be installed on either side of the body. The lift is made of black anodized aircraft aluminum.

The unique rotating mechanism has a wide lever that makes rotation easy and ensures reliable auto-locking of the clamping frame. Thanks to the system of springs and bearings, the frame turns over without wearing of the mechanism. The body of the auto-flip system is made of durable aircraft-grade aluminum anodized in black.

The universal holder allows you to use any abrasive stones with the sharpener, both on blanks and without them. The abrasive holder has no metal plate, but thanks to the special geometry of the stops, it allows you to fix the abrasives as securely as possible. The abrasive holder bar has an increased length of 694mm, is made of steel, and has high rigidity. The holder rod is collapsible and joined by an aluminum sleeve coupling, with a three-point mounting, which gives the maximum alignment of the connection. The rod is equipped with a convenient thumbscrew for adjustment which allows the rod to be connected in one motion.

The Axicube angle finder comes together with the abrasive holder. Developed specifically for sharpening systems, the angle finder is integrated into the body of the holder's movable stop which allows real-time monitoring of the sharpening angle. The Axicube is rigidly connected to the abrasive holder and is in the plane of the abrasive stone. This allows maximum angle accuracy during use. Axicube allows you to set the angle with an accuracy of up to 0.1°. It has a black anodized aluminum body and it is water, dust, vibration, drop, and temperature resistant. Can be used in temperatures from 0°C to +40°C. Charges from a standard micro-USB charger. Each Axicube is calibrated at the factory with verified measuring instruments. Before use, a special calibration plate is used to give it an initial reference angle. If the sharpening device is moved to another surface, a new calibration with the plate is required.

Whole-milled clamps are made of high-strength black anodized aircraft-grade aluminum. The clamps of this type provide the greatest rigidity and stability of the device. Thanks to the monolithic design of the clamps, their main advantage is the increased resistance to abrasive pressure, which ensures consistency of angles during all phases of work, from roughing to finishing. When working with this type of clamps it is not necessary to calibrate and adjust to different shapes of knives. They have a simple and convenient principle of clamping (using a single L-shaped key), and they allow you to clamp a wide variety of knives, including knives with bevels from the spine, folding knives, kitchen knives, hunting knives, etc.

I wasn't sure about some details of your TSPROF K03 PRO BLACK kit. Questions below:

1. Does your TSPROF K03 PRO BLACK kit contain the 2x whole milled standard clamps that the K03 usually comes with, as well as the listed fillet clamps? (It doesn't list them as included.)

I will be sharpening everything from tiny 1.5" long folding knives with flat grinds to heavy thick knives with large cambers to Chinese cleavers (both very thin and very thick) to 12" long Japanese laser gyuto knives to wood carving knives and (hopefully) double cambered draw knives. Steels will be quite a mix: old carbon steel, O1 and A2 tool steels, VG-10, etc. up to harder steels (powdered metallurgy etc.) topping out around 66 HRC.

2. Given the items I'll be sharpening, any recommendations for specific clamps or other items that the K03 might need to handle these?

Note that I already have guides for and freehand experience with my CBN griding wheels, a Tormek with Blackstone Silicone wheel, and a wide range of water stones when sharpening woodworking tools (chisels, plane blades, carving blades, etc.)… See more »

It only includes 3 fillet clamps. 2 of them are whole milled.

For your range of knives, it is hard to tell exactly which clamps you would need. A good optional extra would be the Leading Edge core magnetic platform. With this platform you don't have any clamp limitations.

As far as stones are concerned, I would recommend CBN or diamond for versatility and usability with any steel.

What WAS the purpose of titanium rod?

⚙️Leading Edge  •  1 year ago
Purely optional premium material and slight weight reduction. It makes no difference in sharpening quality or performance.

I could have sworn it was in the listing a few days ago but I ordered this unit last night and I do not see it listed anymore.

The titanium guide rod was removed from K03 PRO BLACK kit in September 2023. Unfortunately, TSPROF stopped selling titanium parts on all markets. At the moment, we have a few alternative guide rods in our lab that we can sell to K03 Pro BLACK owners. Contact us if you are interested.
1) Coupled titanium + titanium
2) Seamless stainless steel + titanium
3) Aftermarket 50 cm titanium rod (to replace one segment in K03 Pro)

I have both the Kadet Pro and now the KO3 Pro. The KO3 came with whole milled fillet clamps and single fillet clamp. My kadet has the whole mill clamps with L brackets. If I use those clamps on KO3, do I need to recalibrate the axicube?
avatar
⚙️Leading Edge  •  1 year ago
Axicube-i sets its calibration to a 14 degree reference angle so only changing clamps won't affect its calibration angle. What does affect the calibration angle, is moving your sharpener to another location on your table or even rotating it in the same spot if your table is not perfectly level.
