TSPROF K03 Sharpener. Start kit


The TSPROF K03 - 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 its sharpness to the next grade.
Sharpening is all about the consistency of the angle. We make the TSPROF K03 of 100% 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, full flat, convex grind knife, machete, and others.


Sharpen knives with any abrasive you like, the K03 universal abrasive holder supports all stones 6" to 8.5" long, doesn’t require 45° bevel on 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.

The kit comes with no abrasives.

TSPROF KO3 Sets the Standard

The first knife I sharpened was an old Buck Hunter from the seventies, It looked like someone tried to use this knife as a wire cutter at some point. Re- profiled it and had it shaving hair off my arm in 30 minutes. KO3 isn't about hype, it's all about quality. Love it❤
