I have a regular leek, and use it as a gents' knife - it's an elegant and classy looking thing. I've practiced closing it one handed, but have stopped as I am running out of flesh on my thumb and middle finger. I wonder why I don't see more button-depressed liner locks. I have a small Magnum knife that I don't carry anymore because the materials are not great, but it has a round bead in the center of the handle that you press to push back the lock, so your fingers are never in front of the edge - a very nice design.
