Fly Knife For Diving

A dive knife (including the fly knife) is an overall tool that scuba divers have used on occasion. It is to cut entangled fishing lines or to knock on their tanks to draw the interest of a companion.

Current dive knives are made with a variety of blade components, including titanium and stainless steel. Titanium knives are both lightweight and durable. Stainless steel knives are simple to sharpen but require more upkeep. You can connect a sheath with a retainer to your devices, such as the back of your console or your BCD.

Sharp tips have the potential to dent your wetsuit, regulator or skin. Spearfishing is more commonly done with sharp knives. The knives’ corners are seamless, saw-sharp or serrated. And also the pointers can be blunted to make the knife secure. They can also be used for chiseling, hacking and digging.

Importance of a Fly Knife

Divers might very well need a dive knife or fly knife to cut fish nets or lines which have become entangled around marine life (like dolphins, turtles and other species) or to knock on tanks to get the attention of their peers. These are necessary for wreck diving because intertwined ropes and underwater grasses are frequently found and must be removed. They are never used as a weapon or to wreak havoc on the marine environment.

A good dive knife or fly knife is required. If you become trapped in a fishing line or ocean kelp, you can release yourself or your companion. During a strong current, you can use this to anchor yourself to the seafloor and avoid drifting. Another advantage is that you are assisting stuck marine life. In addition, your knife can also be used as a tank-knocker to grab interest.

Your fly knife or dive knife usually stored in a BCD pocket or attached to a BCD shoulder strap. The knife can be found in specific spots on certain model types. A few divers are using a specialized diving harness, that has become more popular, and they usually keep the fly knife in a sheath attached to the harness waist strap. If a simple and compact line cutter is being used, a few divers put it on the strap or also called bunggies of the dive computer. In any scenario, one of most essential thing is to always have quick access among both hands to the knife or line cutter.

Choosing your own fly knife or dive knife

When choosing your own dive knife or fly knife begin by making a decision where you intend to carry your dive knife or tool, as this will influence the size you seek. A small knife or shears are your best option if you travel frequently. Once you’ve determined your setup and size range, look for a store that sells diving equipment and tools and buy the fly knife you want.

Examine your grip in your hand. If you generally wear gloves when scuba diving, check the grip while wearing gloves.

Take the knife out of the sheath. Substitute it many times to get a sense of how simple it is. If necessary, do it with gloves on and mounted where you intend to wear it.

Must choose best fly knife or tool for you based on the characteristics that are important to you.

If you dive in places where you might come across discarded fishing line, think about getting two tools: a dive knife (fly knife) and shears, or a Z-knife.


Fly knives are made from stainless steel. When they’re not dried after each dive, they can rust and become useless. This tool was designed to be very sharp and with an indentation which could hook the line but is too narrow to cut an inhaling hose by mistake. Make sure that after diving, you dried-out your fly knife to prevent becoming rust.


In conclusion, fly knives are important not just for cutting fishing nets or getting the attention of your mate, fly knives can also help you in case of emergency (ex. you got stuck in a fishing net). Divers must also know how to handle a fly knife or any types of diving knife that won’t hurt themselves but also not to harm any marine life and cannot trigger other marine animals.
