Serrated scissor for cutting tippet/leader material, trimming flies or performing stream-side surgery, no joke..we have dozens of stories (and unfortunately some photos) from angling MDs and non-doctors who have used these clamps to sew up lacerated anglers or remove hooks from every imaginable place on the human body. We also added a straight edge screwdriver for stream-side reel and boat repair or in my case re-attaching a license plate. This is the closest item we make to a multi-tool.
