My wife asks to borrow my knife quite often and she has said on many occasions that she is glad I carry one. I don't think she approves of me owning a trunk load of them. :o
She has learned to appreciate the difference between a dull knife, a sharp knife and razor sharp knife. I knew we had made real progress when she started asking me to sharpen the kitchen knives because they were too dull. I knew we had broken through to the other side when she started telling me to sharpen the kitchen knives because they were not effortlessly slicing through tomatoes.
Does that make her and edge junky? :D
If she is using a Jumpmaster in the kitchen you need better kitchen knives. If she likes the serrated edge consider a K04 utility. It is thin and the serrations are much more suited to kitchen work. I have the blue handled one and my wife likes it a lot.
