A Proven Icon, Tuned for the Long Road


The Benchmade 940 Osborne has earned its reputation as one of the most versatile and enduring EDC knives ever made. Originally designed as a capable ranch and utility knife, the 940 has evolved into a go-to folder for everything from daily carry to extended outdoor use. The 940BK-03 takes that legacy and gives it a rugged, adventure-ready update.

This configuration pairs a wear-resistant MagnaCut blade with Burnt Copper anodized aluminum scales and a DLC Battlewash finish, creating a knife that looks right at home in dusty campsites, truck consoles, and back pockets alike.



Note from Lone Star Knife & Supply

The 940 is one of those designs that just keeps aging well. It carries slim, it cuts like a bigger knife than it is, and it stays out of your way until you need it. This Burnt Copper version looks like it belongs on an overland rig, and the Battlewash finish is the kind of practical touch that makes you want to actually use it.



Built for Real-World Use

At the core of the 940BK-03 is a 3.4″ reverse tanto blade made from CPM MagnaCut stainless steel. You get a reinforced tip for confidence, plus a long, usable edge for day-to-day cutting. The DLC Battlewash finish helps hide wear and adds corrosion resistance for long-term reliability.

The Burnt Copper anodized 6061-T6 aluminum handle keeps the knife lightweight without feeling flimsy. It preserves the signature Osborne profile, rigid, slim, and comfortable for extended use.



AXIS Lock Reliability

Benchmade’s AXIS Lock is trusted for a reason. It’s smooth, secure, and ambidextrous, and it keeps your fingers out of the path of the blade when closing. Combined with the 940’s balance and carry profile, it’s an easy knife to live with.

At 2.9 oz, it stays lightweight, but still feels ready for real work.



Benchmade LifeSharp Service

Benchmade backs their knives with LifeSharp service, their factory sharpening and maintenance program. If your edge gets tired after real use, LifeSharp gives you a path to bring it back to factory performance, which is a big deal for a knife you plan to keep for the long haul.



What Makes the 940BK-03 Stand Out

  • 3.4″ Reverse Tanto Blade, strong tip with excellent everyday utility

  • CPM MagnaCut Blade Steel, corrosion resistant and tough at 60–62 HRC

  • DLC Battlewash Blade Finish, durable and wear-hiding

  • Burnt Copper Anodized Aluminum Handle, lightweight and rigid

  • AXIS Lock, ambidextrous and proven

  • Slim Osborne Profile, legendary carry comfort

  • Made in the USA, built to Benchmade’s standards

Top-tier engine protection that runs quiet and smooth
Size: 5 Quarts
I’ve used Castrol EDGE in a couple of our vehicles and always come back to it for consistent performance. It extends the time between oil changes and holds up well under both daily driving and highway mileage. We don't "extend the time" though. It's changed, on the dot, every time. The consistency and quality of the oil's condition at change, though, is easily able to be seen that it would go for much longer. Engine runs quieter, and I’ve noticed better fuel efficiency over time compared to conventional oil. Whether that's how attentively I drive and watch the mileage meter on the dash or the oil - is up for debate ;) It doesn’t burn off as quickly either, which is great if you’re keeping an eye on long-term engine health. The bottle design pours cleanly with a smart spout, which saves unnecessary messes in the garage. Pros: Strong wear protection and long-lasting Improves engine quietness Easy-pour design Tip: Use it with a high-quality oil filter for maximum benefit don’t skimp on either part and you'll be golden.

Excellent choice for long oil change intervals.
Size: 1 Quart, Pack of 6
I'm a former dealership mechanic and for years I used whatever we had in the bulk tank which was usually Valvoline conventional. My last job was at a German car dealership. Castrol was the oil recommended by the German manufacturers and that's when I started using Castrol. In my experience Castrol is an excellent oil. My 2014 Ford just rolled over 242,000 miles and even with factory 10,000 mile oil change intervals, from what I can see through the oil fill the top end of the engine is still clean. I've never had to remove the valve cover. It's using about a quart between oil 10,000 mile oil changes which is great because when it was new it used about a 1/2 quart between changes.

ITS GOOD OIL
Size: 5 Quarts
OVERALL NOT BAD BUT USING IT TO SEASON A CAST IRON WILL CREATE A BIT TOO DARK OF A SHEEN. WISH THE MANUFACTURER MENTIONED THAT
