Best Scuba Diving Knives and Shears Buying Guide
What Are Dive Knives And Shears?
Dive, or scuba, knives, and shears are an essential part of the intrepid diver’s equipment.
They’re a one-stop problem solver that’s designed to help scuba enthusiasts and divers free themselves, their dive partners, and ocean life from entanglement in fishing lines, netting, and wires that line the floors of and pollute, the world’s seas.
They’re also able to quickly and effectively slice through wet and dry suits should you need to rescue and deliver immediate first aid to a dive partner.
Designed to be worn in a scabbard or sheath by a diver, and to be easily removed from the said sheath, dive knives and shears are also corrosion and rust-resistant, which makes them ideal for use in the water.
Smaller than an average knife, most dive knives and scuba shears have blades of less than five inches which makes them light, compact, and easy to carry while diving.
Dive knives are also made in two very different blade types, blunt-nosed and sharp-tipped. The latter is a more conventional knife, while the former offers a higher degree of versatility as the tip can double up, and be used, as a screwdriver.
Which Scuba Diving Knife and Shears Is The Right One For Me?
That all depends on what you want a knife or shears for.
If you’re looking for a line cutting tool to help you escape from, and deal with, any entanglement issues, then we’d always recommend the Eezycut Trilobite, as it’s a lightweight, durable, and strong cutting tool that can easily deal with ninety-nine point nine percent of any fishing line and netting that you might become ensnared in, and by.
However, if you’re looking for a more versatile scuba friendly blade, then we’d suggest that you opt for a dive knife instead. In which case, we’d always happily point you in the direction of the Scubapro Mako, which is, and always has been, our dive knife of choice. It hasn’t let us down yet, and we’re more than confident that it never will.
That said, whichever scuba diving knife or shears you decide is the right one for you, always remember the first rule of scuba diving. Be safe and have fun, and maybe one day we’ll see you out there under the waves.
