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.

Customer Reviews

perfect addition
Adam W. on Aug 10, 2020

the 940 is near perfect. the addition of the automatic opening makes it even better. enough said.

That's Right
rick o. on Apr 6, 2022

I was gifted a 9400 black blade and I bought a 9400 satin blade 4 days ago at the Wanenmacher gun show in Tulsa. If you have not made that trip best do it soon. These knives are some better than I expected. 65 years of auto ownership is helpful in determining the status of an automatic knife. These 9400s are artwork, artwork that will last and last. You could edc these knives for 40 years as a concrete finisher, they would not be green or very little black on the blade but the action would still be snappy and the blade could be like a razor.

9400 (940 Auto) Perfection
Jeff C. on Jul 24, 2020

The Good- 940 and everything about it maybe even better. Less screws. No liner. When you press the button you better hold on because the blade comes out with force. The Great - Quality, fit and finish on this one were tops. The blade was centered with no blade play. The blade was sharpe out of the box. The blade grinds were nicely done. The Bad - Im a lefty and needed to move the clip to the other side. One of the screws stripped out because of the amount of lock-tight on it. Benchmade customer service made it right and replaced the screw. This knife is everything it claims and you won't be disappointed.

Great EDC Auto
Robert R. on Jul 25, 2020

I'm very pleased with my new Benchmade Osborne 9400 auto. The blade centering, fit, and finish are all spot-on, and the knife was razor sharp out of the box. The push button is firm and secure and blade deployment is extremely snappy. The 9400 is virtually identical in size and shape with my two Benchmade Osborne 940s which have been my main EDC knives for years. The new 9400 will become a mainstay, along with the 940s, of my EDC rotation

Bad A** !!
Patrick P. on Sep 8, 2022

Benchmade and BladeHQ rock my pocket again! My new EDC 9400, not only looks great but it hits hard on opening! I will forever be a BladeHQ customer!

A must have!
Jacob V. on Aug 15, 2022

My 9400 came very sharp, centered, and with the deepest darkest green anodization that I've seen. Looks black under yellow lighting. Very chalky too. I ordered the 9400 from Blade HQ to retire my oldest 940 and it's easy to say this is an upgrade to the original design which is already incredible. I don't miss the thumbstuds, looks and feels better this way in my opinion. My only complaint is the included split arrow clip. Benchmade should ship it with any of the deep pocket carry clips...Make sure to hold it tight when deploying the blade, such a powerful action! Quite savage for a lightweight knife, but I wouldn't want it any other way.

Beast knife I've ever had.
DAVID B. on Aug 18, 2022

The knife came sharp, very sharp. I call it the matter separator. This is sadly, the second time I am buying this knife. I lost my first one moving. I will always have a 9400.

Quintessential EDC with snappy action
Jim S. on Jul 30, 2020

The 940 is a mainstay in the EDC knife world. The 9400 auto version's action was snappy and definitely needs a firm grip when deploying. Great EDC addition!

My Favorite Benchmade (Almost)
Charlie T. on May 5, 2021

This knife fills all the criteria for a great knife. it is the classic size and shape of the 940, but it is an auto. It fires hard! My only issues are the pocket clip screws being filled like crazy with Loctite, but none on the pivot screw, a tiny bit of blade wobble (to be expected in all autos), and the chalky texture (it is what it is). It is also in need of a mini deep carry clip. overall, I would buy this knife if I were you.

Great knife bad clip
james b. on Dec 2, 2021

The knife is great and was sharp out of the box. The only issue I had was the clip was to tight. I always add a deep carry clip when possible. Once I put the Benchmade deep carry clip on it is great.

Seth C. on Jan 1, 2021

I received the 9400 as a gift for Christmas. This would be my first Benchmade as well as my first auto knife. I’ve always wanted a 940 but couldn’t justify the price. Then I saw the 9400 and had to have it. I’ve carried Kershaws for the last 10 years and have always been happy with the factory edges. I expected the Benchmade to be razor sharp out of the box. It was far from it! It looks as if they put the edge on with a 80 grit belt sander and called it good. I was very disappointed. The 9400 was sent with a free Morakniv that costs $10 and the edge on it was much sharper than the 9400. Fortunately I know how to sharpen a knife. But I certainly didn’t expect to have to sharpen a Benchmade out of the box. Besides the edges I love everything else about the knife.

Delivered fast. Finish & Clip Issues
James F. on Nov 16, 2021

First off, Blade HQ shipped it fast 5 stars on service. As far as the knife goes, here is the good. Unlike other reviewers, mine was quite sharp out the box. Sharper than any other Benchmade knife I own has come from the factory. Spring is very strong, action is smooth. The bad, and my main issue with the knife… the finish is complete crap. After one hour of being the only thing in my pocket, part of the finish disappeared, and bare aluminum was showing through. The other issue is the clip bar is so tight that, I tore the pocket on a brand new pair of Silver jeans. I can’t even use the clip with a pair of AFTCO fishing shorts. While this knife turned out to be disappointing, all my other Benchmade’s have been excellent, so I won’t let this stop me from purchasing their products in the future.

Blade HQ is Awesome product not so much

Blade not sharp from factory looks like you let a monkey loose with a grinder
