Scuba Diver Knives Diving Gear Knife Navy Seal Sheath Blue

I ordered one of these to use on my multi-day kayak trips. I decided to go with a diver's knife cause I wanted something that would not instantly rust if it got wet, and I since I usually wear gym shorts in the kayak I needed something that I could strap to my leg instead of a belt. I just got back from my first trip with it on a river, so I can't attest to it's salt water use, but here is my experience with it...When I first got it and opened the box I noticed that one of the little tabs in the back that holds the blade in was broken. It was still usable, but since that piece was broken I decided to contact the seller to see if they could send a replacement part. They immediately sent me a whole new knife! A+ for customer service.I love the way the it has a fine edge on the entire front of the blade, and a serrated section on the back. The sheath is ABS plastic, not rubber as mentioned in a previous review. There is a spring clip on the knife that keeps it from sliding out of the sheath. I was worried that the rubber straps would cause irritation on bare skin, but it never did and it was perfectly comfortable to wear on my calf for 2 days (about 8hrs each day). So far I have only had to use it for cutting paracord, cutting the top off a bottle, etc. and it seems to do well for general use. Got it wet a couple times and no rust so far. Not much else to say about it other than it's just an all around great knife.The only con I can really think of is that the straps have a belt style lock system and not plastic clips like I thought from the picture, but I didn't see this as a real problem.I'm sure there are other better knives out there, but for the price you can't beat it!

I looked for a while for a diving knife with a point that would be suitable on my calf/ankle. This had the best straps, the best buckles, solid snap in case and a high quality knife with serrations to cut through tough rope. It met all my requirements, and with a bit of whet stone it works quite well and stays in good working shape.One concern, which is fairly easy to remedy- the rubber straps will slip loose from the plastic buckles. I bought a couple of extra strap clips from a boating store for a couple bucks, and was able to adjust the perfect fit for both straps and secure them from being loose ends with the one extra add-on. That's the only reason it gets 4 stars instead of 5. There are few strap and buckle systems that are perfect, especially when you are considering water making certain materials contract, and that rubber has the least irritation in water with skin and hair.Oh, and the snap-in securing system for this knife works very well, I was concerned from photos but you can get the knife out and put it back into the sheath without looking after just a little practice. Well worth this price, would still be a good product for double.

Daily user on Waikiki reefs. Before I go out with it, I carefully pry open the locking spring and goop a bunch of vaseline in, or else it will rust. The Vaseline will stay in and protect from rust for many many dives. I went through three knives at 60 to 80 bucks each before I discovered these on Amazon. Great bang for the buck. Just need to do simple maintenance or dont cry about rust. If you don't want rust, grease it or put out 80 bucks...Oh yea, almost forgot. Throw the straps in the trash and get a ten dollar pair from the nearest quality dive store. Has lasted me years with constant wear.UPDATE: After 1 year my 11 dollar dive knife fell away into the abyss! I'm on my backup knife now. See pic about removing spring and adding lot's of petroleum jelly.

I bought 2 of these, sharpened them and took the on a snorkeling trip. I did not actually use them in the water, however one broke on the first day (case separated) when my calf bumper the side of the boat. It was a light bump onto flexible plastic material and should not have cause it to break since the boat wasn't moving and I was standing in one place at the time. I immediately felt is was a bad purchase so I didn't use the other one. Unfortunately, I was on a multi state trip and I was gone too long to return them.

I bought this for a scalloping trip and after one hour in the water it started rusting however it was very sharp and it served his purpose just not something that you would want to invest the money in if you want something you want to keep for a while it is a $20 knife invest in something worth the money if you want it to last !

I bought two of these knives to settle the nerves of my family about recent shark attacks on the East Coast. We simply strapped them to our left forearms and played in the surf. The knife is fairly difficult to remove from the sheath, you have to press down on the release button pretty hard but after a few times my 11-year old daughter could do it. They do rust quickly so probably want to rub Vaseline or something on the blade and locking mechanism before use, which seemed to help quite a bit with the rust.I was not happy, however, when my daughter ran to me saying the knife had simply fallen out of the sheath. She was playing in the waves with her friends (and me) and when she looked at her arm, the knife was gone (but the sheath was still there). I spent an hour with snorkeling gear trying to find the knife but it was lost in the surf zone so visibility was poor and the waves were beating me up. I was terrified someone would step on it! That didn't happen and we never found the knife. We quit wearing the second knife in fear it too would come loose and we would lose it in the surf. I would say it was worth the money.

This is supposed to be a dive knife, that would be used in case of emergency under water. I find it durable and dont see how it will break or not function the few times a month I will be diving. If a diver that goes in the water almost daily, well then I’m sure they will purchase a more dependable knife for constant dives. As for minimal dives, this knife will work just fine, I hope I never have to use it, and I know I will clean it properly once I’m out of the water.
