Ontario 490 M9 Bayonet System (Green)

This thing is amazing! Fits my mid length gas system AR just like it’s supposed to. Heavy and sturdy, decently sharp. Looks just like the bayonet we carried in the corps.

This is the real thing. Great solid knife that's already sharp out of the box. The sheath is the original one and comes with a clips that allows you to carry it on a belt in a secure manner. The knife has a special hole that fits into the sheath and becomes a wire cutter. I used it in my job and it works like a charm. An awesome knife for any outdoor activity you can think off. If you have a relative or friend in the military, they would great appreciate it. Highly recommended and twice as much if it is sold by Amazon or a Prime merchant--then you know you are covered if anything goes wrong before its in your hands.

There is only one brand to look at when it comes to buying good quality, strong, durable knives... Ontario Knife.I picked this up in December of 2010, spent about 30 minutes putting a good edge on it, and have used it incessantly ever since. Yes, 30 minutes to sharpen it, with a comnination of stone nad diamond embedded stell hones... that itself says that the steel is excellent. A Cheap knife will sharpen in 5 minutes, but will lose it's edge quickly also. You will love the weight of this Bayonet! It mounts easily on my AR-15 (when I hunt hogs at close range, it's a nice close range weapon) and the sheath attaches well and sure to my pistol belt, vest, pack, wherever there is an Alice or Molle spot free.You can look at other brands such as Smith and Wesson, SOG, etc.. but the extra cost for hte Ontario is definitely worth it. I have some S&W and SOG knives, and I'd take my one Ontario M9 Bayonet over 1/2 dozen others into the field.Yes, the wire cutter functions perfectly on barbed wire and horse fence, and a small web strap with velco will ensure that it's secure against your leg when hung on a pistol belt. THIS IS THE ONE TO BUY!

If you want a mil-spec bayonet this is absolutely a great value. Fits on the Moss 590A1 and others as advertised. Some reviewer lament the lack of a full tang. There is a video of this knife being pounded with the blade in horizontal orientation into a tree with a 180 pound guy standing on the grip. I suppose if you want a blade that will allow you to jump on a knife in this manner, you will need something else. Otherwise, very robust.

I bought this bayonet mainly for camping/hiking but also as a survival/SHTF knife. I wanted something large and hefty for heavy-duty work, if needed. I will NOT be using this as a bayonet on a rifle or shotgun. I also have a Buck/Phrobis III version from 1987 but I am keeping that one as a collector's piece. So I bought this current production Ontario version as my "working" or "field" M-9. Here is what I think...Overall Impressions: Comparing it to my Buck, they are very similar in overall design, dimensions, and weight. The Ontario version has a more oval grip vs. the round grip on the Buck. Otherwise they look and feel very similar, except for the color of course. In my opinion, the only true M-9s are made by Buck/Phrobis, Lan-Cay, and Ontario, although I have never held the Lan-Cay version. These were all manufacturers that held or hold the military contracts for the M-9.Blade: The Buck has a flat gray finish on the blade while the Ontario has a black blade finish. Quality seems similar although I believe the Buck steel is a slightly higher grade. For me, the Ontario is going to do just fine as a cutting and slicing workhorse.Quality: The Buck is still regarded as one of the finest versions of the M-9. The problem is they are extremely difficult to find and are very pricey if you do find one. The Ontario is a close second choice, in my opinion. I am happy I have the Buck but I am equally impressed with the Ontario quality.Sheath: As for the quality, they are basically the same. They are both very solid and function extremely well. Unfortunately both of them scratch the blades due to the internal spring-loaded retention device. This can detract from the "new" look but does not affect blade function.I really like having the small pouch on the original Buck sheath. I filled it with a small fire steel, mini signal mirror, nail file, single edge razor blade, and a few band-aids in a small plastic Ziploc baggie. (It's tight, but it all fits) I was able to use the black velcro pouch from the sheath on my Schrade SCHF9 Survival Knife and strap it to the top of my Ontario sheath. Problem solved. I also wrapped a portion of the sheaths with paracord as an extra survival accessory. So, for me, the sheath is now a part of the survival package. The wire cutter adapter on both sheaths appears to feel and work the same. They actually modified the Ontario sheath to be a bit safer, than the original Buck design, when using the wire cutter.Batoning: OK, I am just going to mention this because nearly every online survival knife video shows someone batoning their knife through large cords of wood. To me, this is like taking a Corvette into a jungle. A knife is for cutting, not chopping down trees. Obviously if you DO want to baton wood with a knife, you should us a full tang knife with high quality steel. The M-9 is not a true full-tang knife as the blade and tang are joined (screwed) together under the plastic handle. So you can possibly baton with it but don't be surprised when you snap the blade off at some point.Get something like a Becker BK-2 if you really must baton wood... better yet, get an axe for pete's sake.Sharpening: OK, these are meant to be bayonets, not skinners, so the thick and hefty blades are not intended to be razor sharp. I tried to sharpen them myself with a couple different small pull-through sharpeners with no success. I just could not get the wide angle needed for these thick blades. I also do not know how to effectively use the manual sharpening stone method on such a large blade. Well, I don't give up easily, so I took both of them into a local knife shop for professional sharpening. The experienced and knowleageable gentleman who sharpened the bayonets was impressed with both of them. I had him sharpen the Buck to original specs while I asked to have the Ontario sharpened into a razor-sharp edge for camping, rope cutting, survival, etc. WOW! He did an absolute fantastic job on both of them. My Buck blade is still thick with a fairly sharp edge for thrusting but the Ontario can cut the hair off my arm and slice cleanly through paper. (Next time I am attacked by a piece of paper I can now fight back-no more paper cuts for me) Seriously, I am really surprised how well this large blade cuts after taking it to a pro for some proper "love". Lesson learned, if you don't know how to sharpen this large steel blade, find a pro to take care of it for you.Final Thoughts: As I mentioned earlier, I only consider bayonets made by the 3 military contract mfgs as legitimate M-9's. You can find cheaper versions, that may work for you. If you want the real deal, I can now recommend the current military issue-quality Ontario M-9 in addition to the classic, hard-to-find, Buck/Phrobis III. If you don't know how to properly use a sharpening stone or just don't want to ruin the blade, take it to a reputable knife sharpening pro for the attention it deserves. The extra $10-$20 is more than worth it to turn this bayonet into a sharp, functional field/survival "knife".Thanks for reading...Enjoy your knifes and bayonets!

HIGHLY recommended, get it while you can!

Shipping time right on the money. I was 11 Bravo in the army and had the same exact bayonet and scabbard. The purpose of this knife is to be durable and do the job it was designed to do. Cut tin , wood , pry things apart . At the same time it must be heavy enough to perform combat and ruin their day , hopefully end it if possible. This knife is built to last , and serve a specific purpose. I guarantee it will serve that purpose for a life time if not two. Well built , quality steel , and properly taken care of will be around for generations to come . For its purpose , it's the real deal. Nice cutter and saw teeth that will come in handy. You will sacrifice weight but have confidence this will get the job taken care of. Killer buy .
