Auto Osborne

Inspired by overland adventure and stylish daily carry, the Auto Osborne is Benchmade's nod to the rugged folks who enjoy dusty, gritty, challenging treks across natural terrain. Reimagined with fast-deploying push-button automatic action and an integrated spine safety, the Auto Osborne combines the iconic Osborne reverse-tanto design with the rapid response of an automatic mechanism — for the moments that demand instant deployment without fumbling for a manual lock. The signature reverse-tanto blade geometry balances tip strength with belly for versatile everyday cutting tasks, while the slim sub-half-inch handle profile slides flat in dress slacks and the smallest pockets. At 2.65 ounces with a robust aluminum chassis, the Auto Osborne delivers substantial in-hand feel without weighing down a pocket or pack. The mini deep-carry pocket clip keeps the knife low and discreet, while the durable low-reflectivity blade finish stands up to hard use. Made in Benchmade's Oregon City facility and backed by the LifeSharp lifetime service program.

Auto Osborne Design
Benchmade's automatic version of the iconic Osborne — combines Warren Osborne's classic reverse-tanto design with the rapid response of a push-button automatic mechanism. For the moments that demand instant deployment.
Push-Button Automatic Mechanism
Fast-deploying push-button automatic action delivers the blade with a decisive one-handed deployment — the signature feature that distinguishes the Auto Osborne from the manual AXIS-lock version. Designed for rapid response in demanding situations.
Integrated Spine Safety
Integrated safety on the spine of the handle prevents accidental deployment during carry — the deliberate two-step action required for firing protects against unintended opening. The kind of safety-conscious design that defines tactical automatics.
Reverse-Tanto Blade
3.4" reverse-tanto profile — the iconic Osborne blade geometry. Strong tip for piercing and detail work, with plenty of belly for everyday cutting tasks. The signature reverse-tanto that helped define the modern EDC category.
Aluminum Handle Chassis
Machined aluminum chassis provides the substantial in-hand feel and durability of metal construction — a more refined and rugged build than synthetic scales. Delivers the confidence of a substantial folder without unnecessary weight.
Slim Pocket Profile
Handle thickness of just 0.43" — slides flat against the body for low-bulk carry in jeans, slacks, and dress shirts. Slim enough for the office, substantial enough for daily use.
Mini Deep-Carry Pocket Clip
Reversible tip-up mini deep-carry clip carries the knife low and discreetly in the pocket. Removable for left- or right-handed configuration.
Made in USA
Manufactured at Benchmade's Oregon City, Oregon facility. American-made quality with rigorous tolerances and tight QC.

Cleaning
Wipe the blade and aluminum chassis with a soft, dry cloth after each use. For deeper cleaning, use mild soap and water, then dry thoroughly — especially the automatic mechanism internals, push-button area, and safety interface. Keep the push-button and safety area free of debris that could affect mechanism function.
Automatic Mechanism Lubrication
Apply a small drop of light machine oil or knife-specific lubricant (such as Benchmade's BlueLube) to the automatic mechanism internals every few months — or after cleaning. More frequent lubrication helps maintain consistent deployment speed and reliable firing action over the life of the knife. Cycle the mechanism several times after lubrication to distribute the oil.
Sharpening
The Auto Osborne is covered by Benchmade's LifeSharp program: free lifetime professional sharpening, cleaning, oiling, and re-calibration. Send or visit any authorized Benchmade dealer. For home maintenance, use quality diamond or ceramic stones at the manufacturer's recommended angle; the reverse-tanto blade sharpens easily with standard guided systems.
Safety Check
Periodically verify that the integrated spine safety is functioning properly — the safety should prevent the blade from deploying unless deliberately disengaged. If the safety ever fails to engage or release properly, send the knife in for service before relying on it for carry or use. The safety is what separates a tactical automatic from a dangerous tool.
Storage
Store in a cool, dry environment. The Auto Osborne ships with a reversible mini deep-carry clip — remove the clip before long-term storage if you want to preserve spring tension. Avoid leather sheaths for long-term storage in humid climates (leather retains moisture).
Legal Considerations
Automatic knives are subject to varying federal, state, and local laws. Federal law restricts interstate shipment of automatic knives except for specific categories (military, law enforcement, etc.). State and local laws vary widely — verify your local regulations before purchase or carry. Customers are responsible for understanding and complying with all applicable laws in their jurisdiction.
