Buy Dive Knives for Scuba Diving, Freediving & Spearfishing in Canada
Stay safe underwater with high-performance dive knives from Diving Sports Canada. Whether you're scuba diving, freediving, or spearfishing, a quality dive knife is an essential safety tool. As Canada’s largest dive shop—located in Vancouver—we offer the best selection of diving knives online and in-store. Shop now and dive with confidence.
Why Every Diver Should Carry a Dive Knife
A dive knife is a critical safety accessory used for cutting fishing lines, ropes, or seaweed that may trap a diver. Whether you're exploring kelp forests, wrecks, or reefs, carrying one—or even two—knives ensures you’re prepared for any emergency underwater. Our knives are designed for real-world diving conditions across Canada and beyond.
Best Materials for Dive Knives
Titanium: Lightweight, rust-proof, and virtually maintenance-free, titanium dive knives are ideal for frequent saltwater divers looking for top-tier performance.
Stainless Steel: More budget-friendly, stainless steel knives (especially 420-grade) offer excellent durability and edge retention. Just rinse after dives to prevent corrosion.
Folding Knives vs. Sheath Knives
Folding Dive Knives: Compact and easy to carry, these knives are perfect for divers who want a low-profile tool. Look for spring-assisted models for one-handed operation underwater.
Sheath Knives: With a fixed blade and secure mounting options, sheath knives offer faster access and are ideal for spearfishing or cold-water diving with gloves.
Blunt Tip vs. Pointed Tip Dive Knives
Blunt Tip: Safer for confined spaces, this style can double as a pry tool or screwdriver. It won’t puncture gear and is ideal for beginner scuba divers.
Pointed Tip: Offers sharp precision—perfect for spearfishers and advanced divers needing a piercing tool for emergencies or defense.

Frequently Asked Questions About Diving Knives
Why do scuba divers carry knives?
Divers carry knives for safety and utility—such as cutting entangled lines, nets, or seaweed. They're essential for emergencies and often required for wreck or spearfishing dives.
What’s the difference between a scuba diving knife and a regular knife?
Dive knives are made from corrosion-resistant materials like titanium or stainless steel and feature blunt or pointed tips for underwater use. They're also easier to grip with gloves and often include line cutters or serrated edges.
Which is better: titanium or stainless steel dive knives?
Titanium knives are rust-proof, lightweight, and low-maintenance—ideal for saltwater diving. Stainless steel knives are more affordable and sharp but require regular cleaning to avoid corrosion.
Where should I mount my dive knife?
Common mounting points include the calf, thigh, BCD shoulder, or inflator hose. It should be easy to reach with your dominant hand in emergencies.
Can I travel with a diving knife on a plane?
No. Dive knives must be packed in checked luggage—not in carry-on bags. Always check your airline’s policies before traveling with diving gear.
What type of dive knife is best for spearfishing?
Spearfishers often prefer compact, pointed-tip knives with quick-access sheaths for dispatching fish and cutting lines. Brands like Salvimar and Riffe offer excellent spearfishing dive knives.
Do I need a dive knife for freediving?
Yes, especially for spearfishing or diving in kelp. A small, lightweight knife can prevent entanglement and provide peace of mind in deeper dives.
Where can I buy diving knives in Canada?
You can shop online from our Dive Knives Collection or visit our Vancouver location—Canada’s largest dive shop at 4578 Main Street—for expert advice and in-person fittings.
