Most people don't know how to use a steel properly, and if they do they don't use it often enough! (I end up hiding my favorite knives from my wife for this reason)
After trying electric sharpners, Stones, Grinders, etc. I take my knifes to a professional to have them ground. Using a steel before and after each use keeps my knives sharp for a year or more of constant use.
If you can't find a professional with a band grinder, call your favorite fine dining restaurant and ask the kitchen who does their knives. Most have an individual coming in once every few months for sharpning.
