Questions & Answers

QUINNE P : How do I close it? I can't find a button or anything to release the spring-lock.darrick c : Hello Quinne, in the middle of the handle there is a notch you press down on to secure the blade back into the handle.
ROBERT R : Is the knife blade solid titanium or just titanium coated? What are the other metal parts of the knife made of?Dean A : I believe the blade is solid titanium. I've used it a number of times and it has some scratches but doesn't have any corrosion whatsoever. I'm pretty sure the release is also titanium but wouldn't swear to it. Looks identical and has no corrosion either. The rivets are stainless. My SOG Seal Pup which is a coated blade, is rusty as hell. Plus the fact that this knife is very lightweight leads me to believe it's all titanium.NATHAN S : It appears to be solid titanium. No evidence of oxidation Good solid knifeGerard V : Solid, not coated.
robert w : What is the overall length when open?Dean A : It's 8 1/4" or about 210mm.Gerard V : It should be in the specs area. 8 inches
Shopper : How easy is it to open with a gloved hand?Dean A : Not overly difficult but does take a bit of practice to get proficient. Most folding knives will open pretty easily by just using the thumb but with this one I need to use my thumb and forefinger to get it started and then the thumb can complete the job. Not a big deal, just a little practice. I don't think you could do it with thick cold weather gloves but I can't really speak to that as I only dive in warm water with typical tropical type gloves.ALLEN K : easy enough, very Good knifeRICHARD A : Very easyJOHN B : Pretty easy. I had no issues with 3mm gloves.Gerard V : It is easy to open, even with a 5 mm glove. I haven't opened it that often, but didn't have a problem when I did.
Shopper : Anyone have any idea what the OTHER metal parts are made of? If the pins,spine lock, and spring are all plain steel, then it won't matter how corrosion resistant the blade is. If everything is titanium, I'd be up for one, right now!RICHARD A : Only the blade...but the other parts are holding up as long as I rinse it wellALLEN K : I have been using this Knife for a number of years diving in salt water. Rinse it off with fresh water after every dive, no rust. It is the sharpest blade and holds an edge better than any SS knife I own. My best guess that SS is used for everything but Blade and handle. Won't find better knife for the price

Nice knife.

Sharp, useful, safe and easy to hold. Stowing it so you don't lose it can be problematic depending on pockets.

Doesn't rust, perfect size, great price, convenient

The 60's called and they want their 12-inch thigh-length knives back. I'm honestly not a big fan of carrying knives while diving. They seem to make people think they can carve on things underwater or cut things underwater they shouldn't. I much prefer line cutters since that, for the most part, is all a recreational diver should need a knife for. All of that being said, this knife is nice because it's small, can fit on a BC strap, has a line cutter built-in, and doesn't rust. If you absolutely feel you need a knife, for the price, you can't really go wrong here. Just please don't use it for messing up the underwater environment.

Solid knife. Quite small but gets the job done. Appears to actually be completely rust-proof.

Good Purchase

Good Knife just clip it to your BC and you go. No trying to look like Rambo with some silly oversized commando knife strapped to your leg. I have recommended this knife to many other divers.

Just Works

I purchased one of these maybe 16 years ago, I stopped diving for almost 10 years and resumed again last year, so after years of use and 10 years of sitting in a cupboard I would of though it would be rusted and unusable, not so much the blade but the pins/lock. But no, no rust and is in perfect working order.

Best folding Titanium dive knife

Titanium =Light weight would makes a great travel dive knife 76 gram (2 5/8 oz) Stainless pins through grip non removable. Very sharp on delivery including serrated edge cuts well. Have 500+ dives in salt water [8 years] and NO RUST !! Some reviewers complained line cutter notch catches, this was fixed by detuning sharp top edge with small file. Replaced cord for tougher line and clip. Opens easily left or right handed just pinch notch in spine of blade between thumb and middle finger as it rotates out pop open with thumb. With gloves pinch line cutter or hook it on something and pull back. Note this knife is best for cutting only not prying.

Great back up knife for the money.

Use this as my back up knife. Got rid of the lanyard and added a bolt snap so I can clip it off inside one of my cargo pockets. Great backup for the price!

Great knife. Holds an edge. Cuts fishing line without having to open it. Lanyard attaches to BCD, so no fear of dropping or losing the knife underwater.

Great knife at a great price, I bought this knife as a back up knife that I keep in my BC shoulder strap. It has a few dives on it now, it shows no signs of corrosion. Has been a good, sharp side. Would buy again.

Nice little cutting tool.

Nice and small. Like that you can use the line cutter without having to open the knife. Titanium means you don't have to worry as much about corrosion and stays sharp longer. The down side is that it doesn't have a sheath.

Excellent knife at a great price

Excellent pocket knife. Very sharp and is absolutely unaffected by saltwater. I stick into my BCD's zipper pocket and makes me feel safer during my dives. As other reviews have pointed out, you do need two hands to open and close it, but I don't see that as a problem for me. Also, the line cutter can get caught on stuff, so I would recommend keeping it in a pocket and never leave it dangling during a dive.

O.K. for what it is.

reasonably adequate for price for average vacation diver. Compact to carry but must be bare handed to open the blade. Takes 2 hands. Would carry it as a backup knife.
