Looks like we always fall short on tools, maybe this small Daiwa plier will do the trick.
Is not a tool for tropical or heavy fishing, the small Daiwa plier is pretty well suited for light and ultra-light lure fishermen, both in fresh and saltwater (rinse after use).
It cuts line and braid, crushes and squeezes lead and opens split rings in the 3 to 8mm size. The handle offers a good grip and it has a spring to keep it open.
The small Daiwa plier is simple yet it’s up to the task at a very competitive price.
