I can't remember when I didn't have a single blade knife in my pocket. Maybe because I will be 80 in June and can't remember much any more. Getting back to pocket knives. I like a small single blade, and I have worn out a few over the years. I don't get anything expensive because you never know when you will need to open a can of paint or a can of beans. While hunting or fishing I always carry another fixed blade knife. Keep em sharp.
