I have an Aqua Lung dive knife that goes into the integrated sheath on my Aqua Lung BCD. I loosely call it a knife because it doesn't really cut, and it takes some effort to use, so I want something better. What tool is better for making a quick cut underwater? A line cutter or trauma shears? Or something else? If trauma shears, I assume it needs to be marine grade that doesn't rust and is easy to use. What do you use? I don't want to spend much on this, $30 or less.

TIA!
 
I have a set of Xshears XShear Heavy Duty Trauma Shears - They cost 2-3x more than a really good pair of stamped trauma shears. But they’ll probably last 10x as long (bought my current one in 2019- it has hundreds of dives now.) I started using them after I went to cut some rope with a set that came with my sheath and the blade snapped off. It had some micro defect in the metal that had rusted- figured something like that would make for a bad day if I was entangled underwater.

I keep them in this Dive Rite sheath. It’s compact and easy to use. There are some cheaper versions of this sheath that also work well. Trauma Shears - Dive Rite | Equipment for Serious Divers

For travel I’ll usually bring my shears for my right hand cutter, and will replace my DIR knife with a ceramic cutter on my left.
 
Unbelievably quickly as Edward Scissorhands out come my trauma scissors to cut wire rope even metal
Cutting stuff for years, with rusty rivets, that I whack with a hammer, before a coat of orange rust paint

But I've sure never cut any floating unconscious people out of one piece DIR webbing, with line cutters

Quick quick when is the next useless stuff coming out, I need to get out there and buy some more of it
 
Think step by step, according to the probabilities.
Main risk is a fishing or SMB line --> small line cutter like Eezycut, reachable by both hands
Second step, a bigger rope --> big line cutter in a pocket
Third step, a strong / metal wire (in wrecks by example) --> Cutting pliers in a pocket (not rusted...)
Knife is not the most efficient / important IMHO.
Always show your buddy where these devices are (when briefing)
 
luckily I've just scored a small oxy acetylene set for my back to use with the chest mount rebreather

just in case I headbutt a ship dislodge the anchor and it lands on me
 
A knife may be illegal in some areas and especially in marine parks. Trauma shears are great for cutting wire leader and webbing or netting if the bolt does not rust out and snap when you really need it. Line cutters like the Trilobite are all I usually carry now. I put (a lot of) grease on the blades and change them frequently.

However, apparently along the east coast of Florida the BFK is still a thing so I always make sure to have my genuine titanium Tekna on my waist strap when visiting though I really should get something bigger that straps to my leg like the DMs there. Good grief! :) Just for purpose of fashion.

It was pointed out to me a long time ago, I think on this very board and it is a true thing. If one were to be impaled by a fishing hook or lure which can happen in certain areas what would you prefer to use to cut the line? Shears, knife, line cutter? What if the rusty hook is in your actual flesh of your arm or leg or back and hurts like a mother --------!!!!!!! Now imagine trying to cut that leader, with a hook in your skin with a knife or a line cutter, all by yourself. The only one of the three options that can cut the leader single handed without the line being pulled on as it is cut is with the shears. Of course it is then off to the ER to get the imbedded hook out of your skin, some stitches possibly and a tetanus shot. For me, the worse part of the ordeal would be the shot. I would pass out.

It has been a while back, shore diving near Commercial Pier LBTS, I was doing some photo work, da, da, da, doom (Sea Hunt). I had been contacted by the (fictional) Marine Sea Aquarium to photograph the sighting by a pretty mermaid of the rare coelacanth she had reported while sunbathing. Da, da, dooom. As I was swimming along, attending my mission, I felt a tug on my surface float, ah, well, a rogue wave perhaps and I ignored it only to now find myself being hauled upward from the depths, da, da, da, dooooom. I pulled my trusty Tekna dagger cutting myself free of my surface float though it was a fight but the razor edge parted the cave line just in time to prevent Rapture of the Deep. Upon surfacing to recover my float I found a FWC duo and Flipper holding the end of my surface float line. So he asks me why I am diving without a float and flag and I told him that would be because you stole it from me when you tried to pull me up from 60 feet! So then he asks me what I am doing? Uh, I am on a mission for the Marine Park to photograph beautiful sunbathers, uhm, wait, uh, coelacanths! Okay, well, you are banned from Florida for a year, da, da, da, dooom. The director of the Marine Park was happy to get the photographs confirming the sightings, a scientific expedition would be next to capture the rare beasts for display and a possible fish fry. Join me, Nemrod, next week, for another thrilling episode.

On a real note, assuming the above was not real but it probably might have been, some of these modern, braided Kevlar or Spectra fishing lines just will not cut or they can be difficult. I cannot get a plastic straw with my milkshake because it might impale a turtle but shearing off fishing line all over the place, that is not a danger to marine life and is okay?
