I need a recommendation. I usually carry two knives, one being a 4" or less folder and a pocket knife. I am looking for a smaller knife without a clip that I can use for everyday tasks like cutting boxes and things. I have an Opinel and numerous slip joints that I have used, but they aren't very good for cardboard. My current knife is a Queen sodbuster with a D2 blade. It works well, but is hard to sharpen. I was thinking of a Fallkniven U2, but have never handled one. Any suggestions? Budget is about $75.00.
