Fishing pliers come in multiple different materials, and each has its pros and cons. Materials like stainless steel, aluminum, and titanium are the most popular. They’re corrosion-resistant and sturdy enough for the boat or dock. Stainless steel is very strong but tends to be heavy. Aluminum is very light but isn’t as sturdy as stainless steel. Titanium, on the other hand, offers both blending strength and weight savings.
Steer clear of any plain steel pliers, even if the manufacturer paints them with a “corrosion-resistant” coating. The coating will wear off, and the metal will begin to rust.
