The Benchmade 940 gets a whole lot faster with the 9400! It has the same design and materials as the original, but now it has a plunge lock and a snappy automatic action. This iconic Osborne design is built to be useful knife in any situation. The reverse tanto of the blade makes for the utility of most clip points, but the tip strength of a tanto. The slender build makes it vanish in the pocket when not in use.

Great Auto Knife
Horace S. on Jul 24, 2020

Size weight and quality all great, also not too intimidating to non knife folks.

Carried this for a few months...
Morgan M. on Oct 26, 2021

Like others, I've always wanted an Axis lock 940 and I'm sure I'd be as happy with that one but when the 9400 came out that cinched my hesitation. I used BHQ's lay away plan. Great alternative to busting the monthly budget! Knife is light but not too light, I like a little "heft." It came usefully sharp but I polished it a bit with a ceramic rod. My test for an edc is how well it cuts zip ties. Pressing down on the zip, it is easily snapped the tie in half. Cutting the loop itself is difficult, as with any knife I've tried, but if attacked at a slight angle, it cuts cleanly. Of course, it slices thin strips of paper and is not deterred by cardboard. It makes a nice edc. And, it's great looking! The lavender back-spacer looks nice against the frog green stock. Liners are unnecessary since the stock is sturdy aluminum. The blade is centered and a perfect combination of thick and thin. The thicker part near the handle tapers to a thin Tanto style point, which is good for puncturing or fine work. The blade locks open, of course, and there's also a manual lock that works in either the open or closed position. The opening button is easily located in the dark but recessed enough that it won't open if you lie it on a table and slap the side facing up. To sum up, it's useful, attractive, and a joy to use.

Benchmade Perfection
Nick S. on Aug 4, 2020

I love this knife. I have a 20 year old 940 and got the 9400 to replace it edc. Can't find anything wrong with this knife and love the Osborne design.

Osborne 9400 Auto Green
Larry A. on Aug 29, 2020

Swore to myself I didn't need any more folding knives but could not resist this perfect size in green. wonderful auto knife. Smooth action, exquisite quality.

One of the nicest assisted blades I own
Ed K. on Aug 21, 2020

This is the smoothest opening blade I have. It doesn't try to jump out of your hand but opens quickly and smoothly. I now use it as my EDC.

Benchmade Osborne 9400... Great purchase!
Bernard O. on Jan 21, 2021

The Benchmade Osborne 9400 Auto is outstanding!! I have the black blade with green aluminum scales, and it's just beautiful. I've owned this knife for about three months, and carry it more than all my others. It disappears in the pocket because it's so light and slim. When deployed, it fires out with authority. I wanted a high-quality automatic with safety, and also wanted to own a 940. When the 9400 came out, I knew it would be a perfect match for me. It has not disappointed. Initially, the button and safety were a little stiff and hard to deploy. I also wasn't crazy about that 'chalky' feel of the 9400 scales (which I assume are the same as the non-auto 940). However, after carrying it for a while, the scales have smoothed and are very comfortable. The button and safety have broken in nicely. Overall, very happy with my purchase.

This is the knife I have been waiting for ! I have several benchmade knives , but over the years I wanted something lighter and smaller. This fits the bill, lighter, thiner, and more compact. Hardly know it's in my pocket. The action is flawless and feels good in my hand. Thanks Benchmade.

Had for about 2 weeks
MATTHEW L. on May 10, 2022

Knife is absolutely amazing in every aspect, came sharp, well made, and perfectly centered. After about 5 days of light use the pivot screw started coming loose and it developed a ton of horizontal blade play, fixed by applying loctite and slowly loosening the screw til the spring opened it the rest of the way. I would absolutely recommend this knife to anyone wanting an automatic 940.
