The most versatile series we make and able to handle all streamside tasks. Serrated scissor for cutting tippet/leader material, trimming flies or performing streamside surgery, no joke..we have dozens of stories (and unfortunately some photos) from angling MD&&';;s 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 streamside reel and boat repair or in my case re-attaching a license plate. This is the closest item we make to a multi-tool.
