They get constant use when offshore fishing for cod, haddock, cusk and unwanted dogfish removing dozens of hooks daily. Can't image fishing without them. Also great for removing hooks from stripers and toothy bluefish, preferring the 9" version for these larger fish. Never broke a set but lost a couple and replaced them immediately.
My fiance was completely against me buying this item, because she said I had pliers, and they were good enough. She changed her mind immediately when she removed her hook from a Bluegill effortlessly and without harming the fish.
