Honestly, I find the Kadet (and the Blitz) very finicky to adjust angles because of the arc of angular adjustment. It looks really cool but the type of system TSProf uses on both the Kadet and Blitz is not optimal for this purpose. It takes at least 4-5 adjustments back and forth, resetting the angle cube every time again to get your angle every time you want to change your sharpening angle.
The issue is this - you zero your angle cube on your stone holder (different to other systems), then you place your angle cube on the plane of the knife clamps while adjusting the angle to your desired angle. The major problem here, is because of the angular deflection due to blade width you actually also change your zero reference angle when you adjust the sharpening angle and you have to go back to zero'ing your angle cube again on the stone holder. After zero'ing, you have to go back to measuring the angle on the sharpening plane again, only to find it is different again (because you needed to re-zero your cube), so you adjust the angle again, thereby messing up the zero angle again and you chase your tail round and round until you finally have a small enough angle change to get it perfect. After changing stones you have to compensate for the angle change again, and the whole process starts all over to get the angle tuned in.
The Hapstone, the K03, and the Kazak uses the plane of the vertical rod to adjust your angle, so you zero your cube only once on the angle the blade is clamped and measure the change in angle on top of the stone holders. One-and-done.
Best value for money and excellent quality is the Hapstone R2.
Best innovative system with good accessories and excellent quality (including a light system and many more) is the Kazak Pro Black edition.
TSProf K03 is also definitely a great system, but the accessories are very expensive and its total size is very big.
You'll get your knife equally sharp with any of these 3 systems.
If you want a very good budget option, I designed the Leading Edge sharpening system and made it available for free. All you need is access to a 3D printer and some basic hardware to make yourself one. Here are some links:
Hi everyone :) I've just finished building my "Leading Edge" 3D printed knife guided sharpening system designed by our friend @777 Edge :thumbsup:. The files for printing can be downloaded for free from Thingiverse at: https://www.thingiverse.com/thing:4135236 Loving it ! :cool...
