Frequently Asked Questions

How does the Osborne Burnt Copper Aluminum differ from the standard 940 Osborne? +

The 940BK-03 builds on the standard 940 with upgraded materials and finishes. It features CPM MagnaCut® steel instead of CPM-S30V for improved toughness and corrosion resistance, paired with a DLC Battlewash blade finish for added wear resistance. Both use 6061-T6 aluminum handles, but the 940BK-03 swaps the standard green anodized finish for Burnt Copper and replaces the backspacer with a barrel spacer construction, which is easier to clean, slightly lighter, and gives the knife a more minimalist look.

Who is the 940BK-03 Osborne best suited for? +

The 940BK-03 Osborne is suited for users who want a dependable everyday carry knife built for tougher environments. It’s a strong fit for outdoor use, overlanding, and general utility, while still maintaining the slim profile and versatility the Osborne is known for.

How does MagnaCut® steel compare to the S30V used in the standard 940 Osborne? +

MagnaCut® offers meaningful improvements in toughness and corrosion resistance over S30V, with comparable edge retention. Its finer carbide structure makes it more resistant to chipping under lateral stress, and it holds up notably better in humid or high-salinity environments. It also tends to sharpen more predictably in the field.

What is a DLC Battlewash finish and what are its benefits? +

DLC (Diamond-Like Carbon) is an incredibly hard, scratch-resistant coating that shields the blade from wear and corrosion. The "Battlewash" finish adds a tumbled, distressed aesthetic over the DLC, creating a tactical, non-reflective surface. Its main benefit is durability: unlike solid coatings that show every mark, Battlewash naturally hides signs of use, meaning the blade looks better the more you work it.
