A high sheath works well with a knife small enough in the handle and blade that it doesn't dig into your ribs or get in the way of sitting. I like a dangler best with large blades because it will move out of the way when sitting.
You can attach a leather loop to a key ring and turn any belt knife into a dangler.
You're right of course. I don't carry large knives, hunting stuff mainly with blades no longer than 3 1/2" and usually shorter.
