Choosing the Right Dive Knife
Picking your perfect dive knife isn’t just another checkbox on your gear list; it’s key for keeping things smooth underwater. Let’s cut through the noise and nail the important stuff.
Fast Facts About Dive Knives
When you’re zeroing in on a dive knife, think about what it’s made of, its size, and the blade type. You want something tough-as-nails that’ll laugh in the face of saltwater. Stainless steel and titanium? Yeah, they’re the headliners here for being strong and not prone to rusting (Bladesmithsforum).
| Material | What’s Awesome | What Stinks |
|---|---|---|

The knife’s size also counts. Small and nimble knives are easy to tag along but might falter at hefty tasks. Big ol’ knives mean business but are awkward in a pinch. Plus, you’ve got blade styles to ponder over—drop point, blunt tip, or a utility-oriented emergency knife, each catering to different needs.

Blade Types for Dive Knives
Picking a dive knife isn’t rocket science, but it can really make a splash in your underwater adventures. Dive knives come in a few flavors, each with their own perks. So, here’s the lowdown on the three blade types: drop point, blunt tip, and emergency blades. Each does its own thing, so let’s find the one that’ll have your back when you’re beneath the waves.
Drop Point Blades
Let’s start with drop point blades, your versatile buddy underwater. The blade’s tip is sharp and curves down right into the handle. This design makes it a champ at precision—perfect for slicing up rope or fishing lines.
What’s sweet about drop point blades is their durability. You can go hard on these without turning them into blunt butter knives. Divers who’re all about a trusty cutting companion often go for these. Whether you’re on fish-chopping duty or handling stuff topside, a drop point is your go-to guy.
Blunt Tip Blades
Blunt tip blades? Think of them as the safety scissors of dive knives. They’ve got a flat end that’s almost impossible to puncture anything. So, newbies worried about poking themselves or ruining their gear can chill with this one.
These knives are the Swiss Army of the sea. You can pry, dig, scrape, and even use ’em as a makeshift screwdriver. If you like tools that do a little bit of everything, you’ll love having one in your diving kit. Plus, they work wonders both below the surface and above it.
Emergency Blades
Emergency blades are the lifesavers. Ready to spring into action, they’ve got a serrated edge that’ll slice through stubborn cords or fishing nets like no one’s business. That grip’s perfect for cutting situations where you need to act fast.
Emergency blades are a peace-of-mind tool for divers who wanna stay safe and sound. They’re all about keeping cool when things get tangled and making the escape easy peasy. If you’re new to diving or just want an extra safety net, this is your must-have.
| Blade Type | Key Features | Best Used For |
|---|---|---|
| Drop Point | Sharp, tapered tip, durable | Cutting rope, fishing lines, precise cutting |
| Blunt Tip | Flat, squared-off tip, multifunction | Prying, digging, scraping, general safety |
| Emergency Blade | Serrated edge, cuts tough materials | Quick entanglement release, emergency situations |
Look, picking the right blade type depends on what you’re planning to do and what vibes with you. Dive blades come with their perks, so think it through and choose what suits your needs best.

Maintenance and Care Tips
Taking care of your dive knife is like making sure your favorite tool stays sharp and ready for action—’cause who wants a rusty hunk of metal shortening their underwater adventures? Here’s the lowdown on keeping your trusty blade in tip-top shape.
Cleaning and Drying Dive Knives
So, you’ve wrapped up another epic dive, but before you kick back and brag about your underwater escapades, don’t forget the knife needs a little TLC first. Here’s how you can make it sparkle:
- Rinse with Fresh Water: First things first, give that knife a good rinse with fresh water as soon as you’re back on land. This clears away any sea stowaways like salt and sand, keeping the rust gremlins at bay.
- Soak if Gritty: Got some stubborn stuff clinging to your blade like it’s holding on for dear life? Try a nice little soak in warm, soapy water.
- Gentle Scrub Down: Take a soft brush or cloth to scrub away any leftover grit. Don’t forget the spot where the blade and handle meet—it loves hiding crumbs there.
- Dry Like You Mean It: Grab a towel and make sure every drop of water is gone. Those sneaky moisture bits can sneak their way into corners and bring on the rust.

Dive Knife Mounting Options
When it comes to strapping on your dive knife, you’ve gotta keep it safe and handy. If you’re new to diving, you want your knife secure but also quick to grab in case things go sideways underwater. Let me break down the usual spots to stash your blade.
Leg Straps vs. BC Attachment
Leg Straps: Dangling a knife on your leg has been the classic go-to. Usually, it hugs your calf just below the knee, making it simple to snatch when you need it. Folks like it because it’s tucked away yet easy to reach. Plus, it doesn’t mess with your buoyancy compensator device (BCD).
BC Attachment: Lately, pros are leaning towards slapping that knife on your buoyancy compensator (BC). It’s about grabbing the knife faster in a pinch since it’s up on your torso. No underwater gymnastics here—just snag and slice if you’re caught in a bind (literally).
| Mounting Option | Pros | Cons |
|---|---|---|
| Leg Straps | Easy grab, Old school cool, BC stays free | Might not be super speedy |
| BC Attachment | Quick-draw action, No awkward twists needed | Could bump into BC usage |
Get that dive knife parked smartly so it’s secure and within easy snatching distance. More pros are going for the upper body spots now. Curious about other gear hacks? Peek at our tips on affordable scuba gear for beginners.
Emergency Knife Placement
Besides your main blade, a sneaky lil’ emergency knife is a smart move. This mini-saber acts as your plan B, sitting on your chest or hiding in your BC pocket, ready just in case the big knife plays hard to get.
Torso Mount: A chest-mounted emergency knife puts it in arm’s reach for both hands. Your natural arm swing helps you grab it ninja-fast whether you prefer it pointing up or sideways.
BC Pocket: Stashing it in a BC pocket is another solid plan. Just make sure you can easily grab it and it doesn’t slip out during your adventure.
| Emergency Knife Location | Pros | Cons |
|---|---|---|
| Torso Mount | Both hands can reach, Grabbing it is a breeze | Could mess up strap placement |
| BC Pocket | Nicely tucked away, Won’t jab you | Not as quick to yank out |
Picking the best dive knife spot is crucial for a smooth and safe dive. Your scuba setup should be thought out like piecing together a puzzle. Need advice on other gear?
