PromateScuba Dive Snorkel Titanium Knife (4 3/8" Blade) with Straps and Sheath

This knife is fantastic. It has gone on many dives, both fresh and salt, over the seven years I have had it; it looks like the day I bought it. The blade is practically rust-proof and very sharp. The leg straps are sturdy and don't slip, and they show no signs of tearing. The sheath holds the knife securely. The whole thing feels flimsy and cheap, but I have had no problems with it falling apart. All in all, it is a great knife for the money.

I am so happy with my decision to get this. I was torn between a couple different knives on amazon and finally settled for this one. I paid a little extra to get a knife wth a titanium blade and it's certainly worth it. There is no issue with rust and the knife itself is very durable.The titanium blade itself runs the full length of the knife (I was worried the titanium might stop at the hilt, and that a different metal would be used for the butt but that is not the case). The grip is comfortable and fits well in my hand. The plastic sheath is well-designed. With a secure release system and no little plastic parts I'd have to worry about breaking off. The two rubber straps allow it to fit comfortably and snugly on my leg. I've taken it on over 50 dives since purchasing it. This is a great dive knife.

Pro:Sturdy enough,Made in taiwan,Serration really works,Good for neck knife with light mods including drilling and shortening the handle: pretty secure by its own handle on face down carry daily, to secure more i just add paperclip holes later on.Blunt tip is great for self defence neck knife.Very Light weight.Pretty big/great gripAll product materials is sweat and corrosion resistant, ive tested it in oceanside ca.I got the used one from amazon,its so new!!!Cons:No indication of how much full tang it has.Both side serrated (well, some my like it like this based on preferences)New one pretty expensive, meaning : i can get bigger, thicker yet also light knife by adding roughly 15 dollars to this knife.overall: I like this knife. Not "love" but "like" level

Great Dive knife. Needed a nice titanium knife to take on spear fishing and diving adventures. Love the look and the holder is very secure so no need to worry about losing your investment. Titanium is the only way to go in salt water. Stainless steel knives just dont hold up and end up corroding. The strap is comfortable and fits just about any size calf i could imagine. Product looks just as imaged.Pros: Wont rust, secure holder, adjustable to any size, good construction from blade to handleCons: more expensive than stainless knives,I definitely think it is worth they extra few dollars for a knife you can have forever!

Excellent knife at the right price. Full tang titanium its light and feels great on the grip. Easy to withdrawal and easy to sheath. Unlike other reviews of this knife I found the sheath to be very good in my opinion. Holds the knife very securely, just make sure the knotch latches and there is no movement at all. Is sharp enough as well. I’m 6’ and 175lbs so the provided straps do fit my thigh all be on the last hook, but it’s secure and comfortable. Works well on the calf also. For the price I say this is the knife!

I live in the Florida Keys and dive quite often. I bought this knife in March, 2016. After 8 years of continued saltwater immersion, there is not a speck of corrosion on this knife. Yes, I rinse it after every dive. But still, not even a rust spot. The retention system works flawlessly. Takes a decent depression to release the knife which is smooth. When returning the knife to the sheath there is a noticeable "click" letting you know the knife is securely back in the sheath and won't accidentally fall out. MY ONLY WISH THAT would make this the perfect spearfishing knife is if it were a bit slimmer and more dagger like to better dispatch a fish. I keep looking for a more dagger like knife, but nothing have I found that comes close to the quality of this knife. A tad bulky, but always where I left it, releases smoothly when I need it and still looks brand new.

The knife is awesome, and despite the many complaints I see about the sheath, I have zero. Unsheathing it is simple, you use two fingers to draw alongside the knife handle to unlock it, which after a few motions is simple to do in or out of water. The knife itself is way lighter than I thought it'd be, which is great for a dive knife, and it feels like good quality. It's not that sharp, but its sharp enough for most tasks. A razor sharp edge dulls much quicker than an edge kept sharp, but not finely sharp. You wouldn't want this knife to be razor sharp, keep a small backup knife designed for cutting on you instead. This knife is meant for work, so a razor sharp edge is a bad idea.

I was a little suspicious of this knife since it claims to be titanium at such a low price, but I bought it any way. I'm not sure what alloy of titanium it is, but it does appear to be titanium from the color and weight. This knife is very light, if you're used to stainless steel knives you'll be surprised at how light it is. The metal runs the full length of the handle and gives you a nice end on the butt of the handle that you can bang on your tank and make noise if you need to. Also, the full length metal means that you can do some serious prying without worrying about the handle coming off (I've done this to knives before). The sheath locks securely, there is no way on earth that this knife is coming out of the sheath without you pushing down on the buttons by the handle to unlock it.I got the blunt tip version in blue, but my comments above should be valid for different colors and the pointed tip as well.
