Chuck -
Not sure about the "Ikon" line - but it appears to be similar to the "Classic" line, with a more sleek / modern style.
We have an 9-piece "Classic" set, plus a set of (4) steak knives. We have been using them every day, since we received them as a wedding gift 14 years ago.
We keep ours in the knife block that came with the set. With minimal, proper maintenance, they are worth every penny of what they would cost. Good cutlery is a pleasure to use - you'll NEVER, EVER want to go back to using cheap, crappy knives, and will definitely find doing so extremely frustrating.
Our experience has been that they hold an edge extremely well. There is not a knife in the set that we do not use. I run the steel on the smooth-edge knives frequently, and have touched-up the edges on several of them with a fine diamond honing stone. They are probably due (over-due) for a professional sharpening. But I can still slice onions paper-thin.
If you are thinking of buying a set, I would whole-heartedly recommend them. The Classic is a little less costly. I love the style of the Ikon series, and would expect them to perform similar to our Classic set.
If you choose to "take the plunge" - do as others on this forum have recommended. Store them in a wooden knife-block or cutlery drawer insert, or one of the wood-clad magnetic knife bars to keep them handy. These methods of storage prevent the edges from getting "knicked-up" - which is what happens if you just toss them in a drawer.
