Got one as a gift.
This "system" simplifies the man-of-the-house duty of sharpening knives and things.
And the Lansky gets these things brutally sharp!
The trick/technique behind the device is seemingly in its guaranteeing of a consistent, perfect angle of the sharpened edge. The system itself provides four angles: 1) Heavy-duty tools like an axe, 2) Utility knives such as a pocket knife or ordinary kitchen knife, 3) Finer edge such as used for filleting, and 4) Super-fine (think razor blade).
Coupled with these four angles, the system comes with a variety of hones, from very coarse to very fine. Other sets of hones include stones for serrated edges and diamond dust stones.
Anyway, after setting up the knife in the knife holder, about five minutes with three different hones, will result in a fine, sharp tool.
If you're looking for something better than a short trip to the bench grinder, I recommend the Lansky.
As a plus, your current squeeze will be ever so grateful!
