Benchmade Undercurrent Sheepsfoot Magnacut Depth Blue Fixed Blade BM18040S

The Benchmade Undercurrent Fixed Blade in Depth Blue is more than just a knife—it’s a tough, ready-for-anything companion built to take on the wild side of saltwater life. Crafted for serious marine utility, this fixed blade thrives in harsh, corrosive environments where lesser blades tap out. Its 4.37-inch stonewashed sheepsfoot blade, made from ultra-tough CPM MagnaCut steel, brings exceptional corrosion resistance, edge retention, and slicing power. And with a partially serrated edge, it’s ready to tear through rope, line, bait, and whatever else the ocean throws your way.

The full-tang construction is molded with a durable Santoprene handle in bold Depth Blue, offering a high-visibility, no-slip grip—even when soaking wet. Whether you’re hauling in the day’s catch or fixing gear on deck, this knife stays firmly in hand.

To keep it secure and within reach, the Undercurrent includes a Sonar Gray molded sheath with a quick-access push-button retention release. Designed for belt, pack, or boat mounting, it’s built for right- or left-handed carry—whatever gets the job done fastest.

Measuring 9.38 inches overall and weighing just 5.38 ounces, the Benchmade Undercurrent finds the sweet spot between portability and performance. Proudly made in the USA, this blade is your go-to for waterborne work, high-seas adventures, and everything in between.
