Frequently Asked Questions
Is the Benchmade Auto Osborne 9400 an automatic knife?
Yes. The Benchmade Auto Osborne 9400 is a push-button automatic that deploys the blade with one press and includes an integrated spine safety. Automatic knives are restricted in some states and localities, so please check your local laws before purchasing.
How does an automatic knife work?
An automatic knife like the Benchmade Auto Osborne 9400 uses a push-button mechanism. Pressing the button releases a spring that swings the blade open and locks it, and the integrated spine safety prevents accidental firing. Unlike an out-the-front (OTF) automatic, the blade pivots open on a folder axis.
How do you maintain the Benchmade Auto Osborne 9400?
Keep the Benchmade Auto Osborne 9400 running smoothly by brushing pocket lint out of the pivot and blade channel, applying a light lubricant, and cycling the action. Because it is a spring-loaded automatic, avoid full disassembly and use Benchmade's LifeSharp service for deeper cleaning and adjustment.
What steel does the Benchmade Auto Osborne 9400 use?
The Benchmade Auto Osborne 9400 uses CPM-S30V stainless steel at 58-60 HRC, a premium American steel known for excellent edge retention and corrosion resistance.
What is a reverse tanto blade?
A reverse tanto blade, like the one on the Benchmade Auto Osborne 9400, angles the tip on the spine side for a strong point while keeping a long cutting belly. It is the signature Osborne blade shape.
Does Benchmade offer lifetime sharpening on the Auto Osborne 9400?
Yes. The Benchmade Auto Osborne 9400 is covered by Benchmade's LifeSharp service, which sharpens, cleans, adjusts, and inspects your knife for the life of the knife.
Is the Benchmade Auto Osborne 9400 made in the USA?
