Benchmade 9400BK-03 Burnt Copper Auto Osborne – Precision EDC with Purpose-Built Performance

The Benchmade 9400BK-03 Auto Osborne takes everything collectors and professionals love about the classic Osborne and elevates it with automatic action and tactical styling. Designed for rugged adventure and refined carry, this auto folder fuses speed, durability, and iconic design into one elite cutting tool.

At the core is a 3.40" CPM-MagnaCut reverse tanto blade, a premium stainless steel known for its exceptional balance of edge retention, corrosion resistance, and toughness. The blade’s DLC Battlewash finish gives it a gritty, field-tested look while adding durability against abrasion and the elements. The reverse tanto profile offers a reinforced tip for piercing strength while still allowing for clean slicing thanks to its flat grind.

The burnt copper anodized 6061-T6 aluminum handle is lightweight yet built to endure, with ergonomic curves for a confident grip during precise tasks or extended use. A smooth push-button automatic deployment system is paired with a rear spine safety lock, so you can carry and use this blade with total confidence. Whether you’re opening boxes, slicing cordage, or navigating backcountry trails, this knife deploys fast and locks up solid.

Finished with a black oxide coated split arrow pocket clip that’s reversible for left or right-hand carry, the 9400BK-03 is a standout both in performance and appearance. It's slim enough to disappear in your pocket, yet capable enough to become your go-to blade—whether you’re in the shop, on the road, or off-grid.
