This section provides answers to frequently asked questions.1. Why is your knife sharpener so expensive?
Our TSPROF K03 and Blitz sharpeners are made of the highest quality metal grades: constructional steel and aircraft aluminum 7075-T6. All parts are manufactured on CNC-machines with micron tolerances, and the final assembly and configuration of systems are completely manual. The combination of these factors and product control at all stages allow you to sharpen knives with the help of our systems with an accuracy of 0.1°. Each new part, designed by our engineering department, goes through many stages of testing and verification.
The Blitz sharpener is designed for household use. It is compact and allows you to sharpen knives with a spine thickness of up to 4.5 mm. Great for most kitchen, EDC, and folding knives.
TSPROF K03 knife sharpener is a professional system, that has various types of clamps, including for sharpening fillet-knives, and a universal table for various tools (chisels, scissors, etc.). A wide range of knives can be sharpened in the TSPROF K03, up to 600 mm long and up to 7 mm thick spine.
Choose an abrasive stone according to the purpose of sharpening and sharpened steels. The combination of abrasive with steel also largely depends on the tempering of steel and various impurities in its composition. Therefore, it is often possible to choose the best option for particular steel only by experience. The general recommendations are the followings:
If you have knives made of soft steel with a hardness of no more than 60 HRC, then silicon carbide and aluminum oxide abrasive stones are suitable.
If the steel is harder, the best choice will be diamond plates, as well as diamond and CBN bars. After getting some experience and practice, each sharpener individually selects a set of necessary abrasives.
We ship our sharpeners all over the world, cooperate with various transport companies. Throughout the entire time of our company's existence, sharpeners were delivered to the different remote corners of the world, the most exotic place for today is French Polynesia, located in the center of the Pacific Ocean.
The modern knife industry offers a very large range of steel used for the manufacturing of blades. Therefore, it is impossible to say for sure that the abrasive can always work in the same way. Silicon carbide and aluminum oxide abrasives are more suitable for soft stainless steels and carbon steels of any hardness. At the same time, for powder steels with a hardness higher than 60 HRC, diamond and CBN bars are more suitable. You can often hear that CBN bars can claim to be versatile, but when working with carbon steels and Damascus, they often lead to crumbling-out of the cutting edge. It is also experimentally proven that the use of aluminum oxide abrasives for sharpening ceramic knives is not effective at all, but diamonds and CBN bars cope with this task extremely well. Every sharpener determines the most suitable abrasives for himself and forms a universal set of stones necessary for his needs.
Blitz diamond plates are made by the exclusive order of the TSPROF company. They are made on the galvanic bond and allow you to sharpen any steel with high speed and efficiency. The diamond bars presented in our online store are made by the Venev Industrial Diamond Inc. They are made either on the organic bond or on the improved organic bond (OSB). Unlike diamond plates, they work less aggressively and remove metal more gently. At the same time, such bars are best used for hard steels. Their wear rate is slightly lower than that of diamond plates, and when working intensively on the same steels, they can work longer due to the bond.
Yes, on our TSPROF K03 knife sharpener with the help of a special clamp – a small universal table - you can sharpen scissors. This clamp also allows you to sharpen chisels, plane knives, ice bore blades, and knives with a one-side bevel.
At the moment our sharpeners can't cope with the sharpening of serrations. However, we are working on this issue and our engineering department is developing a special device for sharpening the serrated blade.
Diamond bars have a different service life depending on the bond. Triple coated diamond bars on the galvanic bond are designed for grinding operations and rough sharpening. They quickly and aggressively remove metal. And therefore the rate of wear and tear will also be quite high, it all depends on the work intensity. Venev diamond stones are made on the organic bond. They remove metal less aggressively, but are suitable for full knife sharpening, from rough grinding to finishing. If you sharpen a small number of knives and rarely enough, the resource of these bars will last for several years.
We have experimentally established that TSPROF K03 knife sharpener can sharpen a wide range of cutting tools. Including knives with a wide variety of geometries (multitool knives, daggers) and a blade thickness of up to 7 mm. Among them are fillet-knives, for which we have developed special clamps that allow you to sharpen the knife at an angle of 7.2 degrees. Besides, it is possible to make a convex edge - two special devices are produced for sharpening the blade in such a way. In addition to knives tourist axes, with a flat spine, machetes, parangs, bolo-machetes, swords, and arrowheads can also be sharpened. Also on the TSPROF K03 knife sharpener, you can sharpen scissors, including multitool scissors, ice bore blades, plane knives, shoemaker's knife, and chisels, for all this, a special clamp is created – a small universal table.
The rotary mechanism of the TSPROF K03 sharpener is made of steel and aircraft aluminum of the 7075-T6 brand, designed with maximum reliability of the structure. The rack-and-pinion lift and sliding sleeve are made of 7075-T6 aircraft aluminum. The dovetail joint used in the lift guarantees maximum structural rigidity. So there is no backlash when working on this system.
The TSPROF K03 and Blitz sharpening systems are made of high-strength steel and aircraft aluminum. All components, clamps, and accessories are made of the same materials. This means that with careful use, our sharpeners can last for years. Today we already have many years of experience in using our products by many professional sharpeners. Some of them have been using our sharpeners without replacement for more than 6 years.
If the blade thickness on such a knife does not exceed 4.5 mm, then almost any hunting knife can be sharpened on the Blitz sharpener.
When creating kits, we strive to fully meet the needs of our customers. For TSPROF K03 sharpeners, our kits are designed according to the principle from the simplest configuration, for people just starting their way in sharpening (Start and Start Expert kits), the configuration for a more experienced sharpener (Standard and Expert standard kits), and to the maximum kit covering all the main tasks (Complete kit). For Blitz sharpeners, the same principle of picking is used, but taking into account that this sharpener is for household use. A TSPROF specialist will help you to choose a kit for your tasks, just email us email@example.com or call +1 (888) 9921785.
