SKYSHARK Scuba Dive Knife, Stainless Steel Knife Diving Knife with Sheath and 2 Leg Strap for Scuba Diving, Spearfishing, Blunt Tip 7 Inch Short Blade Knife for Diving, Camping,

This knife is much cheaper than the NRS knife and works well in my NRS life jacket.

My 10 year old grandson is learning to sail and dive. The knife is the perfect size to strap on his ankle and allow him to cut free of vines, nets or fishing line if he should become entangled.

Good little knife for price. Sheath could be more secure. Lost on last dive trip but I liked it so much that I bought another to replace it

Just wanted my husband wanted for our upcoming vacation

A lot of diving gear is large and takes up a lot of space. This Scuba Dive Knife is not like that. It is very compact with a large enough handle that even big hands have no issues with use. The rubber straps hold to neoprene like glue so you don't have to worry about your emergency piece not being where you last placed it.The blade comes very sharp with a serrated edge, regular Knife edge and a curve near the hilt to cut rope or string. There is a blunt metal edge on the handle incase you need it.The sheath holds the knife very tightly. Almost too tight. You don't have to worry about it coming out of the sheath while on the move but it does take some force to remove the knife. If you aren't interested in strapping this to your leg or some other part of your gear, it comes with an extra bit of fabric with some rings and and hook so you don't have to fear losing it while heading to your favorite diving spot. Hook through the sheath and place the ring on your bcd and it'll be there when you're getting set up.I really like this piece of equipment. I feel it is very well made and will serve its purpose should I, hopefully never, need it.

Rusted after one salt water dive with no use of knife.

I have a problem where I collect knives of any price range. This little guy for $15 is worth every penny. Is it the best blade I own? no. Is it unique and fun? Yes! Out of the box it's fairly sharp and with a quick honing holds a nice edge. The handle is compact and comfortable to hold. The sheath holds onto the knife for dear life and takes a little getting use to to quickly remove it. The leg straps work well and have a lot of adjustment. I did find the first few times I strapped it on my leg that I stretched but after that it held tight while wearing it. Really can't go wrong with this knife. Unless you don't like knifes. Than you probably won't like it.

The straps for this knife are 19.5" long. They work for attaching to your calf, but they won't work for attaching to your thigh. The straps also have a very strong smell. I'm not sure what they're made from. The sheath works fine for holding and releasing the knife and it can be inserted on either side. It does wobble in the sheath in a little. The edges are reasonably sharp out of the box but can use some touch up. The handle is made of a hard plastic and fits fine in the hand when using the straight edge. The bump on the bottom gets in the way some when using the serrated edge. I'm not sure how well the blade will resist rusting over time, only time will tell. Based on the quality of the other materials I think it will be fine for light use, possibly more. I wouldn't trust it for heavy use. The main things going for it are its price point and it holds secure in the sheath and doesn't fall out. Beyond that it doesn't really wow. I'd give it about a 2.5
