Diving Knives

You need to carry at least one dive knife with you every time that you go spearfishing. A knife isn't simply for dispatching a fish but can be a life-saving tool if you get tangled in your line by a fish that's running circles around you. Having a backup knife is important as it's easy for a fish to knock the knife out of your hand, or just plain drop it.

Adreno stocks a range of quality spearfishing knives but, like anything, you get what you pay for. A cheaper dive knife will often become blunt and rust quite quickly! It is a good idea to budget $50-$70 for a high-quality spearfishing knife that will last you a lifetime.  Most of the rust to appear on a dive blade will be superficial but still detracts from the performance of the knife.

Diving Knives: Spearfishing diving knives often come as a dagger, with a pointed tip to spike your fish. Edges typically include a smoothly sharpened blade for slicing fish for burly and a serrated edge for cutting through ropes. It is also important to consider how the dive knife is strapped and how it can be taken out for use.  Many people opt to have their knife on their belt for easy access, others run it around there leg but this can be harder to reach, especially if you're tangled.

BC Knives: These are knives intended for scuba diving applications. Many BCD knives are typically stumpier with features such as a blunt tip and line cutter. Scuba divers don't require a pointed tip for dispatching fish, instead, BC knives will have specialised edges and a BC mounting system. This means your knife attaches to your BCD instead of yourself. 

Filleting Knives: As the name suggests, these are for filleting your catch. Long and super sharp blades cut through the skin and fillet of fish like a hot knife through butter when in the right hands. A large trailing point and long bevel make cutting fish meat an efficient process.

Abalone Tools: Otherwise known as Pāua knives, these knives are designed specifically for removing abalone from rocks ideally without harming them. This gives you a chance to return your catch if it isn't to size without fatally harming it. 

Commercial Diving Knives: These are knives intended to be used for commercial applications, and thus are constructed from commercial-grade steel to withstand some serious abuse in the water.
