The only knives I own are my two butcher blocks of carbon steel, sharpenable Chicago Cutlery knives. We got one set for our wedding, many many years ago, and The Man's parents gave us a set (which we had given them. *sigh*) a few years ago.
I try to keep my kitchen knives in good working order, but people keep placing them in the dishwasher which is SO bad for both the wood handle and the blade.
I de-burr the blade every time I use a knife (some of my knives have lost much width of the blade, as I cook a LOT) and I try to sharpen them on a stone at least once a year.
My Man loves pocket knives, and has several sets of them. He had a beloved pocket knife taken away at the airport shortly after 9/11, when he had forgotten he had it in his jean pocket. He always
carries a pocket knife (he says "It's a Man Thing.") and has lamented the loss of that knife for years and years.
We don't have any decorative knives, although my middle daughter, who loves Ren Faires etc has a scary looking decorative knife with a dragon it in and a perforated blade. My dad said, "That thing is evil." LOL!
