Best Divers' Knives & Shears of 2026

"I found this dive knife to be exceptionally sharp right out of the box, and the sheath lock is solid and secure—I never worry about accidental slips. The weight and balance feel just right in my hand. Honestly, for the price, it's a steal, and I'd recommend it to both casual outdoor folks and serious hunters."

"What I appreciate about this dive knife is the classic, versatile blade shape and the strong retention clips that keep it securely in place. I like that it’s a good value, so I’m not too upset if I ever lose it while diving."

"I use this knife when I'm out on my SUP board alone. The blade is sharp and locks securely into its sheath, making it easy to retrieve with a button press. I've worn it both on my calf and forearm. My only gripe is with the straps—they slide off easily when stored in my dry bag, so upgrading those would make this a perfect product."

"I've used this knife on multiple dives and it's performed flawlessly, especially when cutting fishing lines underwater. I liked it so much I bought another for a different location. Well-made and razor sharp, it's perfect for underwater use. I highly recommend it—100% satisfied!"

"The knife is excellent for paddling and camping—not just diving. For the price, it's rugged, sharp, and the hard sheath locks securely, making it ideal for attaching to a life jacket. If you want true marine-grade material, you'll pay more, but for a budget-friendly, reliable blade, this is a great choice."

"I attached this to my life jacket and it's always within reach when boating. I've already used it to cut tangled ropes and it slices far easier than expected. Perfect size and sharpness for my needs."

"I picked this up for my daughter’s rock hunting trips and was pleasantly surprised. The knife and sheath are well made, and I especially like how securely it locks in place. It seems like it will really hold up to outdoor use!"

"This knife has been a handy addition for my spear fishing in the Bahamas. It was inexpensive but the quality is better than expected, and so far, it’s holding up well. I use it frequently and haven’t had any issues."

"After using this knife in the ocean and rinsing it off right away, I noticed rust forming almost immediately on the blade and hilt. With each use, it just got worse. If you plan to use it in wet conditions, it will rust. I’d recommend spending a bit more for a higher-quality knife."

"I noticed the knife started rusting quickly after a few short snorkeling sessions in saltwater, even though I rinsed it with fresh water daily. Also, the sheath setup clearly favors right-handed users, making it awkward for left-handed people like me. For serious saltwater use, I'd recommend spending more on something higher quality."

"While I find it to be a solid and durable knife for freediving, I was disappointed that it wasn't as sharp as I expected. Also, despite careful cleaning, rust appeared after only a few dives."

"This is a great product overall, but if you require true stainless steel that won’t rust, this may not be suitable for you."

"As a commercial diver, I needed something reliable for work, and this spear delivers. It's solid, works great, and my husband loves it for his dives. No complaints from us!"

"I bought this as a backup for a Lionfish trip in Belize and was impressed. Even though it's a bit heavy, the weight helps with underwater impact, and it handles smoothly through my hand. It's great for fish of all sizes."

"I was a little hesitant at first because of some negative reviews, but after using it, I found the build to be solid and travel-friendly. The aluminum is thicker than fiberglass, giving it sturdiness, and it breaks down nicely for packing."

"This knife is sharp, well-made, and always gets the job done—no matter what I need it for. I keep it on my hip throughout my workday, and honestly, I can't imagine going without it. If you're looking for reliability, this one's got it."

"To me, this is the ultimate diving knife—sharp, reliable, and a real pleasure to use underwater. The wrapped handle offers a fantastic grip, and the included storage sleeve feels like quality. The only hiccup is the straps could be sturdier, but with a little DIY, they're easily improved. If you're up for a bit of customization, this knife is definitely a great catch!"

"In terms of quality for the price, this knife is really impressive. Both sheaths are user-friendly, and the safety latch is a handy feature. The knife arrived very sharp, but the stretchy leg straps are a bit tight for my legs—not really the knife's fault, just something to keep in mind if you have larger thighs. I'm planning to swap out the straps for something more comfortable."

"In my 40+ years of diving, I’ve rarely used a knife, but this knife/scissor combo is exactly what I needed. The case mounts perfectly on my BC and, while a bit large, it’s not cumbersome. This is much better than a standard dive knife."

"I’ve just started scuba diving and haven’t tried these underwater yet, but on land, the knife is sharp and the scissors cut extremely well. The sheath holds everything securely, which gives me confidence knowing I have it with me."

"I really wanted to like this tool, but removing it from the holster is tough—you have to press down hard on two tabs and slide it out, which isn’t easy. The plastic labels were coming off before I even unpacked it. The design could use some work."

"I've used this knife on several dives and really appreciate its secure fit and easy quick-release mechanism. The straps are made of durable rubber and fit comfortably around my arm, thigh, or ankle. The knife stays snug in the sheath and is barely noticeable when walking or in the water. I'd recommend this to anyone looking for a dependable diving knife for both in and out of water."

"What stands out for me is how the Cressi Skorpion blade feels solid and dependable underwater. It's sharp enough for basic cutting tasks and gives me a sense of security while diving. I trust it to do its job every time I need it."

"While the price is good and the blade is large, I found the straps a bit too short to fit my upper thigh, and the sheath’s button is somewhat tricky, especially when wearing gloves. I wish it was easier to unsheath one-handed."

"I've been using this dive knife for a few weeks and am truly impressed by its razor-sharp blade, sturdy build, and reliable locking mechanism. The sheath stays secure, and the leg straps don't slide even on longer dives. After several saltwater sessions, there's no sign of corrosion. For the price, this knife gives me peace of mind underwater and performs like a premium product."

"I was pleasantly surprised by the solid quality and sharpness of this diving knife, especially given its affordable price. The lightweight design makes it easy to maneuver underwater, and the sheath and straps keep it secure during dives. It's definitely a great value for those looking for a reliable and budget-friendly dive knife."

"I picked up this knife mainly for self-defense and leg carry. I like that the straps keep it in place, but I wish one strap was shorter to avoid excess. I also found the blade not as sharp as expected and it can be a bit tricky to remove from the sheath with one hand."

"I've had this knife for about a year and am genuinely impressed by its lasting sharpness and comfortable design. For the price, I honestly didn't expect such reliable quality—it's comparable to much more expensive brands. The only minor issue was the paracord wrap being a bit loose, but that was easy to fix."

"I take this knife on all my dives, and it's been extremely durable and rust-free, even though I rarely rinse it off. It easily locks into its sheath and is always sharp. The lightweight feel makes it perfect for regular use."

"My husband uses this knife on every dive and finds it very sharp with a secure sheath. The only thing to note is the leg strap tends to loosen up, which he quickly solved by tying a knot. After a year, it still shows no signs of rust or wear."
