The principle of the sharpening system is that the stones are drawn over quillons on the clamp clamped in the blade by these quillons are guided in the clamp.
Thus, the grinding angle is always kept realtiv evenly.
The system is rather interesting for small diameter to max. about 12-13 cm blade.
Otherwise you have to clamp the knife again and then it is just already time consuming the knife re-tensioning - 2 times spans per side at 3 stones makes then already 12 times Clamp + last stone the burr removing where you then have more often times the blade side switches = too expensive.
Since I use he prefers a Wasserstein and have since just may not be kept as clean every angle.
In addition, the included instructions for beginners is interesting, but you should do to really efficient and a good job with the set with y-tube video: How To Sharpen a Knife - Gough Custom watch.
Although the used diamond stones, but the only difference is that you should lubricate the stones of this set.
Otherwise, I'm really satisfied.
Am curious how long hold the stones.
