Benchmade 18040S Undercurrent

Built for the water, made for the mess—this fixed blade is your go-to for rugged, wet-work utility where folders fall short.

When the job’s too dirty or the conditions too slick for a folder, the Benchmade Undercurrent™ steps in with dependable, full-tang performance. Designed for anglers, boat crews, and maritime pros, this fixed-blade beast features a 4.32” CPM-MagnaCut sheepsfoot blade with partial serrations—ideal for sawing through rope, netting, and wet line with control and power.

The high-grip Santoprene® handle provides a confident hold even when soaked, while the Sonar Gray injection-molded sheath with a push-button release ensures fast, secure access from your belt, pack, or PFD. Compact, easy to clean, and tough enough to take a beating, this is the blade to reach for when the water gets rough and the work gets real.
