Frequently Asked Questions
Is the Benchmade Auto Osborne 9400BK an automatic knife?
Yes. The Benchmade Auto Osborne 9400BK is a push-button automatic with 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 9400BK 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 9400BK?
Keep the Benchmade Auto Osborne 9400BK 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 9400BK use?
The Benchmade Auto Osborne 9400BK uses CPM-S30V stainless steel with a black coating, giving it strong edge retention, corrosion resistance, and a low-glare finish.
