The Crux – MagnaCut Rescue and Utility Knife.

The benchmark for what a PFD mounted knife should be.

Meet the Crux—our most advanced rescue knife to date. Built from ultra-corrosion-resistant MagnaCut steel and fully skeletonized for weight savings, this is the mac daddy of all PFD-mounted tools. Whether you’re punching through a coastal inlet or locked into a Class V slot, the Crux was made to ride shotgun on the kind of missions where your knife has to be as dialed as the rest of your kit.

This is a purpose-built tool, born in Maine and made for the water—from the salt-sprayed Atlantic to your local steep creek. 

Key Features

  • MagnaCut Blade Steel – The gold standard for saltwater performance. High corrosion resistance, high hardness, no compromises.

  • Ultralight Skeletonized Handle – Slim, weight-cut profile with secure grip when wet or gloved.

  • Blunt & Drop Point Options – Available in both tip profiles for your mission-specific preference.

  • Made for the PFD – Compatible with our Lash Tab Clip, MOLLE bracket, and paracord/zip tie mounts. Built to stay put in the chaos.

  • Highly Retentive Kydex Sheath – Included with every Crux. Molded in-house for rock-solid retention without the need for gimmicky screws. Snaps in with confidence and stays put until you need it.

  • No BS. All function. – No gimmicks. No unnecessary features. Just a knife that does its job—beautifully.

Who It's For

  • Guides, paddlers, and water pros who demand the best.

  • Sea kayakers, river runners, coastal operators—anyone who plays hard where it’s wet.

  • Those who understand that when things go wrong on the water, your knife matters.
