Benchmade Intersect 18050 Fishing Knife with MagnaCut Blade

Benchmade Intersect (18050) – Compact Fixed-Blade Fishing and Dive Knife

The Benchmade Intersect is a small, fixed-blade knife built for quick, one-handed access in wet, slippery conditions.

If you are a diver, snorkeler, or water-based angler looking for a compact cutting tool that stays out of your way until you actually need it, this is worth a serious look.

What You Are Getting

The Intersect is a fixed-blade knife, which means no folding mechanism to fumble with and no moving parts to corrode or jam after repeated saltwater exposure.

The blade is 2.68 inches of CPM-MagnaCut steel with a plain, drop-point edge. Drop-point means the spine curves gently down to the tip, giving you a broad, controllable cutting edge rather than a fine point. That shape is well-suited to cutting line, netting, or kelp, where a sweeping cut matters more than piercing.

CPM-MagnaCut is a relatively modern powder-metallurgy steel that balances corrosion resistance with edge retention better than many traditional stainless alloys. For anyone spending time around saltwater, that matters.

The overall knife, including the handle, is compact and lightweight at 2.36 ounces. You will barely notice it clipped to your BC, belt, or gear bag.

The Handle and Grip

The handle is Santoprene, a vulcanized EPDM rubber and thermoplastic composite. In plain terms, it is a grippy, slightly flexible rubber-like material that does not become slick when wet.

The handle also includes jimping, which refers to the small notched ridges cut into the spine and handle. Those ridges give your thumb a purchase point when you are making precise cuts or working with gloves on.

The color on this model is Depth Blue.

The Sheath and Carry

The included sheath uses a quick-mount system that clips to pockets, belts, backpack straps, and waders. For divers, that flexibility means you can position it wherever it is most accessible on your kit without being locked into a single attachment point.

The sheath holds the knife securely enough that it will not shift during entry or movement, but releases fast when you reach for it. That combination is exactly what you want when you need to cut something in a hurry.

Maintenance and Long-Term Ownership

Benchmade includes their LifeSharp service for the life of the knife. Send it in and they will re-sharpen the blade to a factory edge, clean it, oil it, and make any adjustments, at no charge. For a knife that sees regular saltwater use, that is a meaningful long-term benefit.

After any saltwater dive or fishing session, hand-wash the Intersect and dry it immediately. That is standard care for any cutting tool used in the ocean, and the MagnaCut steel is more forgiving than most if you are consistent about it.

Who This Knife Suits, and Who It Does Not

The Intersect is a compact utility knife, not a prying or heavy-cutting tool. The 2.68-inch blade is well-suited to line cutting, net clearing, and light fish prep. If you need a longer blade for filleting or a serrated edge for sawing through thick rope, this is not the right choice.

It is also worth noting that camping and hiking are the primary uses this knife is designed around. The knife works well in water environments given its materials and grip, but it is not a purpose-built dive knife with a line-cutter notch or blunt tip. If entanglement rescue is your primary concern underwater, look for a knife designed specifically for that.

For a diver or angler who wants a small, reliable, well-made cutting tool that disappears into their kit and is ready when needed, the Benchmade Intersect is a genuinely capable option.
