Diving Knives

A dive knife is a crucial accessory for any experienced scuba diver. Whether you're cutting line, adjusting your gear, or spearing fish, you'll need to have a reliable dive knife handy. Our dive knife collection offers a number of stainless steel blades, all of which come with non-stick handles for ultimate traction, as well as sheaths to keep your knife comfortably within arm's reach. Many of the blades in our dive knife collection double as flat-head screwdrivers or other useful tools.

Each dive knife we sell, like all of our products, is backed by a 60-day money-back guarantee, so you can be confident you'll get the product that fits your needs. If you're interested in learning more about which knife is right for you, read our Dive Knife Buying Guide.

It is exactly what it is promised to be! I got this knife specifically for our yearly beach trip. Kept it tethered to me swimming in the ocean. Got back to the house washed it off and after a week of that nota hint of rust

This is a badass little knife! I got it for boating/snorkeling but it is a great hide-out knife as well. The sheath sucks though, too hard to draw. Needs modification, I wouldn't dive with knife/sheath as-is.

The knife is of good steel but not finished properly -edges & hole are not beveled or polished, rather poor quality for a Spyderco knife. That being said, the Spyderedge is extremely sharp and the scales grip well bare-handed or with gloves. I like the H-2 steel for it's corrosive resistance.

Good knife received order on time!

I got this for a gift and when I opened it up, my first thought was how sharp it was. This knife came with a wicked point, and it popped out of the sheath with a little force. For the price, a great buy.

Sharp, hasn't rusted in any fresh water, and case is pretty sturdy.

Perfect fishing knife (with line cutter) at a reasonable price. Great service/prompt delivery

This item will be great for the purpose that I purchased it for.
