Do you need a scuba diving knife? Well, some people might think that scuba diving knives are only for fighting underwater monsters, but in reality, they are crucial pieces of equipment that every scuba diver should have on their belt.
A scuba knife, like any pocket knife that you would use on the surface, can come in handy in more ways than one. Servicemen originally wore them during World War II for military reasons, but nowadays, a scuba diving knife is mostly useful for untangling yourself under the water.
From fishing lines to seaweed and other traps, while you could slowly untangle yourself with the help of a buddy, having a scuba diving knife on your ankle can make the process quicker, saving you precious time and oxygen.
