Reviewer: Tyler Livingston
I own many knives, and know that each has its pros and cons. But this knife is a cut above the rest. Its decently sharp, has a very rugged serrated edge, comes apart and goes together easily, the sheath locks in the knife very well and allows a very quick release, and the handle is very well designed and provides a great grip. The only complaint I can come up worth would be that the screws that hold the sheath together are prone to rust, but are easily and cheaply replaced. 10/10 would buy again.

Rating: love the knife , hate the handle & the straps
Reviewer: Michael M.
Have just used the knife on a live a aboard for a week. The knife held up well, but the handle cap rusted on the 1st dive out. By the end of the week about 1/3rd of the cap is now rusted. They need to coat the cap so it will not rust with something. The straps are difficult to use. I took the straps from another knife to make it more user friendly which seemed to do the trick. Sorry guys need to be honest

Great titanium knife for its price! Only have 6 dives with this knife and had to use on the first dive to cut myself free from some fishing line! Knife did the job very well! Handle could be a little heavier for my taste, but in all great knife.

Rating: Best Ever!!!
Reviewer: Monica Burton
Wow - We have both had other regular AND titanium makes, models, sizes, etc, but this one has got to be the best weve ever had... nice and secure with their straps, and the handle feels comfortable with and without gloves. Quality of the blade is superb, and the design is perfect for diving purposes. AND the PRICE was OUTRAGEOUSLY LOWWWWW! Prices are always good for anything at, but I must say we both feel like we almost STOLE these!!! Thank you,!

Rating: Great purchase!
Reviewer: Amanda W.
My experienced (and ultra particular) bf needed a new dive knife, which I know nothing about. After researching key features, I found this one, which had EVERYTHING I was looking for in a knife PLUS a great price, and I shopped around a lot. Bonus= he agreed and loves it too. Its exactly what he wanted!! Great purchase!! Thank you!

Reviewer: Jarred R.  -  View all my reviews
When the knife arrived I was happy with the quality. The knife was sharp and well made. The only issue I had was the sheath. I thought it was well made, but on my third dive with the knife it fell out and I lost the knife. If you can secure it another way it would be great. Thats why I gave the knife 3 stars.

    greetings 2-questions please. 1-is this model knife solid in terms of feel and noise, no rattle or looseness in handle to blade or knife in sheath? 2-on the pummel end, is the very butt-end flat and smooth so as to be used for hammering a nail (in emergency)? picture doesn’t show pummel end. thanks

    Darrick  (Certified Scuba Instructor at

    Hello David, there is no rattle with the knife in or out of the sheath, As for the end cap, that is a rounded end and if you unscrew it you can take the knife apart for cleaning.

  • Carl:

    Not a question but a comment. I bought two of these knives a few years ago for my daughter and I and they are fantastic! We have used them in the Great Lakes, Atlantic Ocean, Gulf of Mexico and the Caribbean. I posted a question about replacement parts and received a response right away. Next thing I know, I receive an order notice for my lost part (at no cost). Talk about great service! Thank you!!!!!

    How does this knife release from its sheath. Ive found some release mechanisms hard to find/ feel with gloves on. I like the release on the XS scuba titanium but its out of my budget

  • Derek:

    Is the yellow colored knife a fully yellow handle or does it just have a yellow stripe like in the picture? The bright color is a good idea, but a fully yellow handle isnt the most appealing.

    Aaron  (Certified Scuba Instructor at

    Hi Derek, The handle only has a small about of color on them.

  • brian:

    I know they say the Titanium knives are very sharp but once it does need to be sharpened is it possible or easy, can you use a regular sharpener to sharpen it?

    Arthur  (Certified Scuba Instructor at

    Hello, yes they sharpen the same way as steel. It''s just going to take a little longer since it''s a harder metal.

  • Tyler:

    Could you mount this on a bcd or would you have to have a leg strap for this knife?

    Darrick  (Certified Scuba Instructor at

    Hello Tyler, no this is not a knife you would mount to your BCD. This is considered a large knife and does not have the option to mount to a BCD. If you are looking to mount your knife, take a look at: This knife would be the one you are looking for if you want to mount it to your BCD.

  • Todd:

    Is this knife made in the USA ?

    Arthur  (Certified Scuba Instructor at

    Hello, no they are made in China. Even if a company says that something is made in America it rarely is. The loophole is you can manufacture the individual part overseas and assemble it in the US and say "made in America"

The Scuba Titanium Dive Knife by is the primary tool every diver should have underwater to assist in clearing entangling obstructions such as kelp or monofilament fishing line that can ensnare a diver. All too often discarded or lost fishing nets look harmless enough until the diver gets close and their fins or gear gets entangled in it on the seafloor. In these cases the Line Cutter and a good Serrated Edge become important features. Secondary to these a metal butt cap that can act as a tank banger and is an extremely useful feature when a diver needs to get the attention of a buddy who has strayed a bit too far.

The Scuba Titanium Dive Knives offered by meet these needs perfectly. The blade is constructed entirely from Titanium for superior corrosion resistance, light weight and strength. It boasts a 12.7cm blade length and an over-all length of 25.4cm with the addition of the comfortable handle with lanyard attachment point. With a serrated edge that is perfect for sawing through anything that may obstruct the diver and with a line cutter edge the diver will never have to worry about entanglements. Added to these features is the solid metal butt cap designed to allow the diver to make more than enough noise to attract the attention of the divers around him or her.

The knife is kept secure to the diver’s leg and ready for use with a single action, locking system sheath that allows the diver to remove and replace the knife easily and quickly with one hand and two included depth-compensating leg straps.

Scuba Titanium Dive Knife


Dive knives are something most instructors don’t spent a lot of time explaining to their students. Normally the topic is sped past during the equipment portion of a class as something everybody should have with possibly a sprinkling of “why” in terms of safety. Most dive classes are more interested in the exciting gear we all want to learn about such as a regulator or bcd, figuring we all know what a knife does. All too often we as consumers purchase the most inexpensive knife we can, find simply to have one strapped to our bcd or legs, only to find later on we’ve not purchased what we’d hoped to.

Stainless steel corrodes even with the best of care, and typically doesn’t hold enough of an edge to cut air, let alone much of anything else. Mini knives are inexpensive and a bit less cumbersome when mounted to your gear as opposed to your leg, but if you are diving in conditions requiring 3mm or thicker gloves, gripping one can be a challenge as our loss of dexterity through a layer of neoprene makes them difficult to use.

The Scuba Titanium Dive Knife takes into account everything a diver should need to concern themselves with when considering which piece of equipment to choose. It has a very comfortable hand grip that allows for a secure grasp of the knife even with thick cold-water gloves on. At its base is a large metal butt-cap that is terrific for using as a tank banger to get or keep the attention of a dive buddy or class. A hole drilled in the end of the hand grip allows the diver to use a lanyard or possibly mount some sort of retaining device to the knife if you are in an environment where losing it is going to be an issue. I’m not a huge fan of a lanyard on my knife, as I feel it is just another thing dangling from my gear to get fouled on the reef, or me or what ever, but I am sure there are situations where it would be a very handy feature to have. The titanium construction of the knife will help eliminate corrosion concerns and hold an edge very well, a fact I’ve all too painfully found out myself a time or two. The blade has every feature that a diver should deem important. It has a very sharp straight edge, but more importantly the other side has a serrated edge that runs nearly the entire length of the blade. This edge is much more functional when used under water and is a MUST for any good dive knife. The final blade feature that is something every dive knife should have is the line cutter. The perfect tool for slicing through mono-filament fishing line or pesky kelp strands. The knife is available in a blunt or pointed tip depending upon your preference.

Included with the knife is a very sturdy, hard plastic sheath that is secure but allows for easy one-hand removal of the knife and 2 leg straps. All in all, one of the best values for your money in a dive knife. If you want a knife that is strong, sharp, won’t corrode and is a real piece of scuba equipment then the Scuba Titanium Dive Knife should be your first and only choice.
