Scuba diving knife

So many divers here have recommended a shear that I'd like to ask what they think of the Leatherman Raptor which goes for about $60. The Raptor can be carried folded or in fixed position and features:

  1. 420HC Stainless Steel Folding Medical Shears
  2. Strap Cutter
  3. Ring Cutter
  4. Ruler (5 cm)
  5. Oxygen Tank Wrench
  6. Carbide Glass Breaker

I'm asking this in combination with another thread: Looking for a water rescue knife w/ a glass breaker feature.



No..just no.

As divers we should strive to eliminate failure points not increase them. "Keep It Simple Stupid" should be your mantra.

Bill Maine's approach is just as relevant today as it was in the past. His approach to cutting tools was essentially a steak knife cut in half with the point rounded off to prevent penetration.

A diver's knife is used to cut line. Period. Shears are an excellent choice for steel leader. Some divers may have the need to pry, but they will be a slim margin of actual divers.
 
I am a new diver and I'm driving myself nuts looking at options for dive knives, so this thread is helpful. Does anybody have any thoughts about the Spyderco Enuff Salt as an option?

Whatever knife I carry, I am also planning to dive with a trilobite webbing cutter and a pair of shears.

Thanks


Looks like a solid choice.
 
Hey all, I think this might actually be my first post here... don't remember.

Anyway, I'm getting into diving, so this forum is very helpful. My question here is this: for those of you who recommend shears as part of your dive rig, where and how do you carry them? Do you have a sheath setup for them? Where are they easily accessible? Etc? Pictures of carry options would be very helpful as well.

Thanks,

Hobby Diver by myself - Using a Spyderco Salt now for over 60 Dives in Salt Water - no Issues, no Rust . I think the basic question is what you want it for: Working (cutting Ropes...) under water or as a Backup. I´m happy with what i have and never needed it under water so far.

Question to all the Divers reading this: Anyone tried a pruning shear as a dive Knive replacement? Heard some rumors - should be perfect under water in case of emergency to cut Rope of fishnet and they are cheap

Dave The shears typically come with a Velcro closure pouch that can be weaved into a harness strap, BC waist strap or clipped off. This is my freshwater setup. You can see the red pouch of my Zknife. In saltwater I swap the Zknife for the medical shears because I don't care how sharp your knife is it won't be cutting through wire leader.

Medical shears is the typical choice.
 
I dive with my mission knife in titanium. It holds a very good edge and will never rust.
Expensive but I love that knife.

Per my earlier post, I carry 2 shears and 2 small knives. I carry one each on the left and right so that I have the ability to grab the needed cutting implement with either hand.

My shears (in nylon pouches as shown in syntaxerrorsix's post) are attached to my BC in the pectoral region using plastic tie-wraps.
I carry the MacNett knives mounted horizontally on straps I have attached to the front of the BC. Actual position changes as BCs change,

The problems I see with pruning shears:
-cheap metal that WILL rust even with decent care
-extra weight. Most pruning shears with any strength of construction are also fairly heavy.
-will not work (well, if at all) on baling wire, small cable, fishing leaders, barb wire fencing

The medical shears will cut all of the above. They are light weight and most of the blades are a stainless steel of some sort. They will rust eventually but not at the drop of a hat like pruning shear will.

The negatives I have experienced with the medical shears is that:
- when, not if, they get dull, they are difficult to sharpen properly.
- while the BLADES are stainless, not so the pivot. THOSE rust just looking at them. In fact, EVERY medical shears failure I have experienced has been the pivot failing after becoming corroded. Another reason I carry 2 pair. If one craps out, you still have another pair. Same 2nd reason for 2 knives - if you loose one, you still have one. Hung up on fishing line 2 feet under the water is just as bad as 100 feet.

With diving, redundancy in safety equipment is a must as anything can and will fail.
EVERY student I have ever worked with has had this beaten into their skulls.
 
I realize this is an old thread but I just have to add my two cents.

At lot of responses were directly aimed at answering the question about a good scuba/diving knife...which is good.

But what if you're out in the water or on a boat - far from shore or civilization - and you suddenly go from diving to surviving? What if you go too far out or storm pushes you out to sea and your boat gets wrecked on a deserted island?

I don't know if 420 or a folder is going to hold up to splitting coconuts for a few months or years.

It still makes sense to have a strong fixed blade on you for emergencies.
 
In general its frowned upon dragging up threads more than a couple of years old.

This thread is from 2014 (or rather the post prior to your post is) - it would have been a better tack and just as easy to start a new thread, describe your scenario and debate the solution.
