Great video with lots of information. Maybe there's one more point worth mentioning: If a diver (or marine life) is tangled up in ghost gear, it's quite difficult to cut them free with a two-edged knife without putting them in danger. That's the reason why in sailing a rescue knife is always single-edged with a blunt tip (and usually serrated). So, better have a knife like this on you or a dive cutter or scissor. Personally, I wear a knife and a dive cutter on my BCD, both made of titanium and fixed in places I can reach with either hand.
I have been in several tough spots when diving that required my knife. My advice on placement of dive knives is to keep it on your calf. The problem with the whole BCD thing is that it is not easily visible when its that close to your body so you have to kind of have to feel around to get it and then unclip it. The worst part is putting it back in the sheath as you really have to use two hands and guide it back in. Someone not being able to reach their calf when diving is just hard to imagine, it's half as hard as touching your toes!
I have found that side wire cutters are the best for fishing line especially if there is an active fisherman on the other end. Moving a line to remove or relocate just may cause the fisherman try to SET the hook.
I wish you the best on your diving career. I hope it will be a life long passion for you. The statement accumulate gear raises a flag to me. Research and seek good advise on your diving equipment purchases.
How's the gear purchases going? I completed my OW a month ago and have just purchased a; Cressi Z1 mask, Waterpoof B1 6.5mm Dive Boots, Waterproof G50 5mm Gloves, and Waterproof H1 5/7mm Bibless Vented Diving Hood. I plan to get the Scubapro Fusion Dry Snorkel and the Mares Avanti Quattro Plus Fins next and then save for both the Shearwater Teric Dive Computer and the Scubapro Everflex 7/5mm Wetsuit. Scuba Gear wise I want the Scubapro Hydros Pro BCD and the Aqua Lung L3gend Elite 3 stage bundle
I normally carry three, one larger one on my calf, a smaller one on the opposite arm, and a line-cutter in my BCD pocket.The one I have has replaceable crossed blades of the 'Stanley' style. So far, I've never needed any of them.
I like the dive shop my son uses as a new (4yr) diver he is still learning about his equipment and the dive shop really helps him select the right equipment.
Well, I have to admit that I have a passion for knives..I literally take 3 or 4 with me every time 😅😅 I know, pretty compulsive.. mainly affected from technical aspects of diving
Titanium is an awful material for knives, it doesn't hold an edge, and can't be hardened like steel. I use a Spyderco Atlantic Salt knife made from H1 steel, which is a variety of Stainless Steel that physically cannot corrode (As I recall there is one of their Salt knives in a jar of salt water at their Hq in Colorado that's been in there for about 10 years and still shows no signs of rust)
I have an IST knife with 10cm s.s. blade, mount it to my BC under the left weight pocket with some zip ties. Never had to use it under water. But I always have a nice sour green apple with me on the boat after my dives. so the knife is useful for cutting the apple to share it with other divers. Don't see the need to upgrade to titanium anytime soon.
I use a pointed knife spearfishing. My wetsuit has a right thigh outside knife pocket. Before I would attach the sheath to my left forearm. Stainless. I have tossed a stainless that saltwater got between handle and shaft. Never seen a titanium knife.
I've got a line cutter on my shoulder and a Scuba Pro Mako (titanium) attached to the top of a pocket which I can reach with either hand. #askmark The Mako sheath is sprung loaded, but is the spring titanium or steel?! The last thing I want is the spring to rust out and the sheath drops my rust free knife!! I really can't see, do you know..
500 dives in. Carry a Aqualung squeeze, but never once have I use it 🙄 When I first started buying kit I got a Oceanic 6” blade to strap to my leg, you know, old skool traditional as I thought. That knife now rest in the bag of all the the other bits I wasted money on. Less is more.
I know if you travel with Stenaline (I use this mainly to travel to NI) that you need to get a knife permit from them before travelling and then announce you're carrying to security and provide the permit. I don't have a dive knife yet but thought I'd ask them beforehand to save me the hassle later
Sheepsfoot knife and a line cutter. Free diving looses the line cutter and spearfishing adds a stiletto. Maybe it's just because I frequent wrecks where entanglement is an ever present risk, but I'm of the opinion that a knife is mandatory piece of gear. It should be a knife too not "knife like". I'm not saying go Rambo but line cutters aren't good enough.
I carry two. Both mounted to my Tech Shorts. One on either side, both are pretty small. I still got one of my massive dive knives that mounts to my lower leg. Maybe I’ll carry it again someday but it’s not really practical.
Sod the coral rules don’t dive without a knife it saved my life & if your in dark water like the uk you may want a little backup one & a main.. I keep one on each leg they both are the same & they have shears on them integrated in the design..the 2 straps on each holding them also keep air out of my dry suit legs.keep at least one knife that you know cuts rope & being new doesn’t mean it’s sharp. A point isn’t important even if you hunt.don’t forget you need two as they do get lost when you need it your life depends on it,
I went with the aqualung big squeeze knife, stainless steel with the sheep foot edge. Definitely considered the titanium but decided against it at the time. Have not had to use it since purchase other than when I tested it out.
Titanium is still too expensive and harder to sharpen than steel. I will admit titanium knives are less expensive than they use to be. I have one stainless steel knife that is 40 years old (and it is small). But, stainless takes much more care than Titanium.
Wow. 304 and 316 while "good" stainless steels in general, are absolutely not good "knife" steels. They are not "knife" steels at all. Won't hold an good edge more than a handful of cuts, but I guess for a dive knife that does not matter much as corrosion resistance is more important.
survive. Actually proved by accident that area swimming pools dont really check when divers come in with their equipment.i 4got when they went to practice to remove his knife from his bcd.
Hidden in your underwear is a bad idea. As long as your dive knife is kept with the rest of your dive gear it can be explained as sporting goods. Airport staff are used to seeing dive knives and it's rare that it will become a problem if they see one mixed with other scuba equipment. Most dive knives aren't very offensive today neither, so as long as it isn't 6+ inches it should be fine but double check with your airline before your trip.

I always dive with a knife, but have used mine far more often to cut limes for cocktails after a dive. Still an important piece of kit.
UK Remora Titanium
have u ever considered it as fighting material?
So you basically have a lime cutter.
Sounds ideal to me! Better to not get tangled in anything in the first place than to expertly cut yourself out!

Never dive without 2 cutting devices...titanium knife and a small line cutter...all compact and out of the way until you need them
I just had my first ocean dives yesterday. (I am getting my OW certification.) I am so excited! I just need to accumulate gear.
I wish you the best on your diving career. I hope it will be a life long passion for you. The statement accumulate gear raises a flag to me. Research and seek good advise on your diving equipment purchases.
I still remember my first ocean dive. I was on the hook from day one. So happy for you!

A pointed tip is ideal for dispatching a fish when you are spear fishing.

Take a drink every time he says dive knife (knives) 😳
Nice to see you gave your dogs a big hug. 😉

Cressi makes a titanium pointed knife I use it Spearfishing

pointed tip is better if you get attacked by a shark or giant sea monster like a giant octopus monster or squid

Small knife mounted on my BCD hose and larger strapped to my inner thigh..not as big as croc Dundee's though lol
A line cutter on the right shoulder strap 1 problue titanium on waistband and a second problue in a pocket
The main reason to carry a knife is so when a hungry shark comes calling you stab your dive buddy and get the hell away from him/her.
Titanium is still too expensive and harder to sharpen than steel. I will admit titanium knives are less expensive than they use to be. I have one stainless steel knife that is 40 years old (and it is small). But, stainless takes much more care than Titanium.
Im Lucky I only had to use a knife two times until know. Had to cut some fishing line.
Wait until a moray eel has grabbed your hand and wont let go :) now that was fun!
I've had to whip out and use a knife in a real hurry to avoid getting garrotted by a rope.
I carry a Kiwi Lazer 'Green River'

Stainless steel: 304 don’t bother.
316 or 420 is the best option
Titanium is too expensive and when you lose it, you’ll cry 😂
How do you guys travel with dive-knifes?
Hidden in your underwear is a bad idea. As long as your dive knife is kept with the rest of your dive gear it can be explained as sporting goods.

Checked luggage. Don't put it in your carry-on bag.
don't buy a cheap knife, just a decent one on sale. You ARE going to loose it and never see your $300 dollar knife again.
2 line cutters and 1 shear ..
Here In America land I like to carry my dive glock
I buy this one 😂😂
Shud give more examples as in show rather than just narrate it .. just a suggestion... Narrating alone kinda gets boring to watch after a while ...
