I have used numerous methods to sharpen knives. I have used the Tormek, it worked. Usually, however, if the knife is appropriate for it, I just use the work sharp knife sharpener. I have an older high grit polishing belt that I have applied green honing compound to. Does a great job. I consider this fool proof if it is appropriate to your knives.

I have at least two different systems that hold a sharpening medium in a "V" shape. THe idea is that you hold the knife vertical, then "cut" down the sharpener. This sets your angle. It is very fast and easy to use. This is one example of one.... not one that I own, but an example.

One of my "V" sharpeners has triangle shaped stones, and you can sharpen against either a flat or a point. I forget the name. I also have one with round ceramic stones. By round, I mean a long cylinder. It is simple, fast, and pretty reliable.
You want something that reliably uses the same angle.
I found that I was able to get a very nice edge using my water stones, but, it was far more work than either of the other two. If your stones are always setup up and ready to go, however, you can touch them up as often as you need to.
The knife that I usually use, I keep sharp on a steel, and then I sometimes do a serious sharpening. The knifes used by the rest of my family, well, i never know what they are doing with those. I think they are using them to cut stone or something since I cannot keep them sharp. I mean, i get them sharp, then next time I check them, they are very dull, so the steel does not work from that state.
