Ontario XM Strike Fighter 2-S Automatic Knife Black Aluminum (3.75" Black Serr)


  • Black serrated blade made from 154CM steel that is tough and easy to sharpen.
  • Push-button opener with quick automatic action.
  • Textured black aluminum handle that has ergonomic jimping.
  • Button lock with a spine-loaded safety lock to prevent unintentional blade deployment.
  • Three-way reversible pocket clip for convenient everyday carry.


In order to be issued to the United States Army, a knife must meet a list of strict demands for durability, consistent manufacturing, and price. A very short list of knives have made the cut, and the feature-rich OKC XM Strike Fighter stands proudly among them.

The XM Strike Fighter's handle is made from milled, textured, and hard-coat anodized 6061-T6 aluminum with a pocket clip that's three-way reversible for both tip-up and tip-down carry options. Its tanto point gives the knife extra strength and piercing power, and its partially serrated edge easily chews through fibrous materials, and will keep cutting long after the plain edge goes dull. Here is an automatic knife that is reliable, highly-functional, and ready to get to work.

The 2-S XM Strike Fighter has a wide blade, a deep-push button, prominent serrations, and wide handle milling.

ADAM B. on Apr 28, 2022

Best, sturdiest auto I've ever had, a little bit heavy but comfortable, this is a Mil-spec knife with incredible tightness, tolerances, and snap. Wish I could get another one!

I struck gold!!!
Alphonzo F. on Sep 16, 2021

On arrival... It is near perfect..... So I got this bad boi on sale for $60, best purchase 2021. So I have like a small scratch on the knife and it is a little tough to deploy, but when it does... Straight fire! The handle has a really interesting texture and sound (like a mix of rock and metal)

Worth it
Todd L. on Jul 28, 2021

Was hesitant from some of the reviews but this is a great work knife for $60 period, did a rem oil flush and moved the clip to tip up carry and very satisfied, take a chance, it’s built like a tank !!

LANE W. on Jul 26, 2021

Great Knife, I use this knife a lot in my EDC rotation. Came very sharp, love me some 154CM Steel as well very high quality and I've had for a couple months now and used heavily to cut everything from wire I use as an electrician to paper and cardboard and it's as sharp as the day I got it basically so it really holds an edge well. Not sure why the bad reviews this is an insane deal for only 60 dollars the msrp price of 280 is definitely accurate for the quality of this Knife.

Got a good one
STACY O. on Jul 20, 2021

From reading the reviews I was hesitant to purchase this knife but the price came down so much I ordered two! I am glad I did! I guess their quality control is hit or miss because the knives I received were as good as anything else I paid what original retail is on this knife. The automatic action isn’t as fast as some but it gets out there quick enough. The safety on mine work perfectly and the knife overall is nice and sturdy. I have no issues with the ones I received after almost a month with them.

Nice knife!
Randy B. on May 10, 2021

I have a small collection of automatics from Dalton to Lone Wolf. This is an awesome knife at this price point.It is well made. Yeah the back lock is not tight. But! The push button is solid enough I have no fear of misfiring in my pocket . 154cm isn't considered top shelf anymore but could be worse.Nice strong spring and nice feel in my hand.

Wow! My new favorite auto
nelson b. on Mar 18, 2021

My new knife has all the zip and clip I'd ever want or need. Made a video to send to a friend (bragging) and he said the blade opening was invisible, so fast, Locks up tight. Ontario sharp. So - i ordered two more for my excellent son in laws. Step Grandson? Wife said NO. Maybe I 'll order a fourth one and leave it where only he'll find it and play dumb. He'll be 18 in June.

Very well built
Clark H. on Dec 8, 2017

This is an extremely well built knife. It feels very good in the hand, just the right amount of weight. The button lock is solid, locks up tight, almost to tight, but doesn't feel like it will " break loose". The only CON for this knife would be the spring, its "slow". The spring just doesn't have the "pop" I like. That is the only reason it doesn't get a fifth star, the spring.

For $60 WTF
Kenneth B. on Aug 23, 2021

Solid feel in hand , sharp & when open it feels like a $275 knife . (Original price $350) .That's where it ends . Lock is sticky , blade release hesitant , lock is flimsy & dulls to quickly (properly bad heat treat). Compared to my $275 Protech which is quick,smooth& just as solid feeling .you see why it's a good $60 knife. It is my new beater . Actually for a split second I thought of buying a few more but sounds like quality control is weak .

I'm Disappointed
Dave C. on Oct 22, 2021

I'm a big guy with a big hand, I like big knives with a little weight to 'em. The pros: I like the size and weight, it feels good in my hand. Very sharp out of the box. Cons: The price, $60 is too much. The button to deploy the blade needs to be completely flush with the bottom of a concave well, not an easy task, the button on mine requires a bit of thumb strength to achieve the goal. All this defeats the purpose of an automatic knife to be quick and easy to deploy in a pinch. I have tried to loosen this knife up for several months with no success. The safety slide does not employ "red your dead" system, it's all black. There are much better options for automatic knives at this price point. I advise do not buy this knife.

Save your money
Adam J. on Oct 10, 2021

I don’t understand the $275 MSRP. It reminded me of a flea market knife. I gave it away a couple of days after I received it in the mail. The person I gave it to loved it because he had never had an automatic knife. Every knife has a place & purpose.

Pass if you can
JARED R. on Sep 29, 2021

For 60$ not a bad knife but has I paid the 300$ I would be returning. The opening mechanism is super tight and hard to push. The knife overall is decent but not the best

Comfortable grip and not worth the time
Charles B. on Sep 17, 2021

Up front the Original price is insane for a 154CM blade. The design is comfortable in hand and when working knife. The button is tiny for it not being on the surface. Action is adequate after activating very stiff button. We even wet lubed one and dried lube another both to no avail. Sharp factory edge that didnt last very long. We have to give this a solid 4Stars because of the price and since its difficult to find a automatic with serrated blades. Update after a month of ranch work. Do Not bother ordering this knife unless you need a automatic butter knife. This knife doesnt hold a edge. Honed twice daily and sharpens....dull after opening less then 10 burlap and plastic bags.Frustration is a mild word, typically Ontario does much better.

Not a great auto knife
Travis D. on Aug 30, 2021

I gave the knife two stars, one star for blade durability and its nice cutting edge, and another star for the customizable pocket clip. This is not a $275.00 knife marked down to $59.99. It's a $30.00 knife marked up to $59.99. Right out of the box the actuator button when pushed would not release the blade. After taking it apart and removing the safety lock feature, and sanding down the actuator button body with 600 grit sandpaper, and leaving the blade pivot screw so loose it will only stay threaded with a heavy-duty thread lock, the knife finally opens as it should when the button is pushed. The button is so recessed on the handle there is no way it could accidentally open in my pocket. I have $15.00 auto knives from the tourist trap stores in Oatman, Arizona that work better than this one. Save your money.

Poor blade release
IKE C. on Jul 17, 2021

If you think your getting a deal on this knife because of the mark down don’t buy it it’s very hard to flip open not a knife I would like have on me if I needed one.

poor blade release
John R. on Jun 16, 2021

Considering the original cost of this knife I was expecting a higher quality product. Overall the normal quality I expect from Ontario. Blade centered, sharp and mostly well built. The button release for the blade is my only issue and it works occasionally. The button release feels like it binds when it is depressed. Tried some oil and only had a slight improvement on the button working properly.

Ontario Strike Fighter
Chris R. on Apr 20, 2021

Not sure what to think. On one hand, it was shipped very fast. Ordered on Saturday and received on Monday. However, the blade is so off centered that it is almost touching the handle when closed. I asked in the description on the payment page that they check for blade centering and it must have been overlooked. So, now I have to send it back and either get another one or just get my money back. I will say that it sure as hell doesn't feel like a $400 knife that Blade HQ is claiming! the 154CM stamp on the blade is even half hidden by the the top of the handle when open. QC was definitely lacking. I was hoping my first auto would be a good one but now I'm rethinking the whole auto thing. I just scored a 1980-81 three dot Buck 110 for $40 on the bay and I might just stick with that considering that it doesn't have moving parts. I can update this after I figure out what to do.

Excited then disappointed
MARTY S. on Jan 30, 2021

Received knive on a Friday and by Saturday it no longer worked automatically. I will update review after I figure out the fix to this problem thru blade hq or OKC. Both have been emailed with my issue, so wanted to enjoy my first full auto knive

Honestly feel like I got ripped off !!!!!
W.C. B. on Feb 10, 2022

I honestly feel like I got ripped off ! When I bought this knife If it wasn't for the 154CM blade steel, I would call this a total piece. It is extremely hard to deploy and when it does, the blade barely opens on it's own. I haven't taken it apart to smooth everything up and try to get it operating properly because every time I look at it I am disgusted with how sh@tty the QC of this knife is and how much I paid for it. I've collected knives for 40 years and I don't mind doing some minor tweeks but a knife that is suppose to sell for...the only thing you should have to do to it, is enjoy it. I put this in the top 3 of the worst knives I've owned (would've been #1 if not for the 154CM blade). I highly recommend passing this one by.

Benjamin R. on Feb 2, 2022

If knife gets cold . Will not open. Death push for button to open and death push button to close. I would never taje thus knife hunting or use it if my life depended on it. Currently modifying to open and close the way it should have come from the factory 🙈SMH. Now i know why the knife is DISCONTINUED!!! Never would have bought it. Thought it was a Gerber!!! LESSON LEARNED!!!
