For a general “multi tool” search, the strongest matches are the on-the-water pliers and cutters. Mustad Blueline 5.5" Mini Tool Scissors is the most compact option for cutting line, crimping, and hook removal. Grim Reaper Pro Pliers - 7.5" Multi-Use Heavy Duty Tool adds split-ring work, line cutting, and crimping for heavier rigging. Shimano Power Plier Split Ring Tool is best if you regularly tune lures or open split rings. Samaki Stainless Steel 280mm Multi Purpose Plier with Gang Hook Opener is a solid rust-resistant plier choice. K9 Fishing Multi-Tool is a simpler all-in-one option with a knife and saw.
Use these as rigging and fish-handling tools, not as lures. Keep one clipped to the boat, kayak, or belt for quick line cuts, hook removal, split-ring changes, and lure tuning. For braided line and tougher terminal tackle, the heavier pliers are the better pick. For fly tying, Nirvanaonthefly 3 in 1 Bodkin Half Hitch Brush Multi-Tool and Hareline Dubbin Kuchelmeister Multi Tools are bench tools rather than on-water tools.
Switch to a dedicated split-ring tool if you’re constantly swapping trebles or tuning hard baits. Choose compact scissors if you mainly need clean line cuts and light crimping. If you want fish-processing gear after landing fish, Kombo Fishing Multi-Tool - 2-Pack is the better style of multi-tool. If you meant an underwater viewing tool, Aqua-Vu Multi-Vu Revolution is the relevant category instead.
