It's obvious that the people who have written these reviews are not professional chefs or even people who have used these knives heavily for any length of time.  If they had, they would have noticed that the thick metal whatever-the-heck-it-is at the bottom of the blade does not sharpen.  In other words, as the years go by (just a few years mind you) and you have to have your knives sharpened occasionally, the blade will wear down, but the thick metal part at the handle WILL NOT.  What does that mean?  It means that your knife will become somewhat bowed, and that you will no longer be able to cut all the way through whatever it is you are cutting.  In essence, it does not make sense to make ANY PART of the blade thicker than another.  It just won't wear evenly.  Trust me on this, I've been a professional chef for 14 years.  Even back in culinary school, we did not use these types of knives.  They are for the occasional user and for show only!!!
I am not disputing the quality of Henckel knives!  I love them.  In fact, I encourage anyone to buy them...  Just buy the GOURMET series, which is what any real professional uses.  They'll last until the day you die, they are far less expensive, and they wear EVENLY.  Unless you are just buying these for show and you want to look cool...then by all means, buy the pretty knives.  Just try not to sharpen them more then a couple of times for the rest of your life.
