THE BEST Mil-Spec Bayonet/Combat Knife!!!
I use this knife for just about everything you could think of! I mostly use the top 5-inches of the blade unless I need to cut rope with the serrated part. I have NEVER seen this knife break or fail anywhere. This knife came semi-sharp but I like to sharpen my knives anyway so now it's stupid sharp! This knife is WAY tougher than the Ka-Bar and I'm so glad I have this knife. It can also be used as a chopper if you're out in the woods. It's a very good utility/combat knife. I don't have a rifle to mount it to, but I can mount it on a stick and use it as a spear. I love this knife, it's a great knife for survival purposes.It is full tang and you can see just how thick the tank of this knife really is which is very thick indeed!! I use this knife as a beater and it's held up great so I will most likely buy another to keep in the box. This Bayonet is worth every penny, don't under-estimate this knife at all!!!

Bad*** knife!
I use my knife every time im out in the woods. It wasnt as sharp as i would have liked but thats an easy fix. Long durabel blade that gets all the jobs i need it for done. The sheaths buttons could be some of a problem when you start using the knife but when you opened and closed it a few times all things about the knife is great!

amazing knife!!!
knife is amazing. It mounts very sturdily to my MOLLE II FLC. It also mounts sturdily to my AR-15 rifle and is hard and sharp enough to go through nearly everything I was able to try the knife on. again, this is an amazing knife to depend on.

Boot camp experience
Just graduated boot camp (parris island)...we used these for bayonet training a couple different times. They get the h3ll beat out of them...slashing hard rubber targets or wood, stabbing them, and just getting the h3ll beat out them. I never had one or saw one break or have any problems. Very durable and does their job well.

OKC3S Review
The OKC3S impresses me and it is obvious that many people--including the end users--were in the design process. I favor daggers because of the double edge capabilities so the OKC3S doubles as a high penetration dagger, fighting knife and woodscraft knife. The edge came with would be good for its intended purpose as a bayonet but I wanted a sharp 25 degree angle. The metal is a very tough high carbon steel so it took me 3 sessions to get the 25 degrees blade sides. The weight of the knife now slices typing paper and shaves with ease. I hacked some vegetation and the knife is still razor sharp. The sheath is also well designed and can be carried many ways. I teach self-defense, hunting, survival and firearms so I believe the OKC3S might be the perfect knife for this aspect. I also ordered an expensive lamp but it popped when I first used it. The KC sent me a mailing label to return it immediately. I went ahead and ordered a Oight M10 with the tact kit to steer clear from old fashioned Iri lamps. Excellent customer service!

USMC Combat Bayonet
Bought this for my son to use when he is shipped to Korea. This is an excellent knife that can be used in multiple ways, it also happens to be a bayonet. Despite what certain presidents may say; there remains a great deal of use for a well made knife that can also do bayonet duty as well in the modern military.

Excellent knife, excellent price, excellent service
I first saw this knife in a military ribbons/medals catalog for $285. I was going to buy it anyway. Then I saw Knifecenter's offer for $100. Howard took my order over the phone. Top notch customer service. Email notifications kept me in the know - even when backordered - nice! Free shipping! This knife has little touches that impressed me. The serration valleys are even with the straight edge portion and the serration peaks are higher than the straight edge portion - wow! This blade shape is good for camping, hiking, bushcraft, survival, and combat, and it also works as a bayonet. I like this blade shape/thickness so much, I am going to buy OKC's SP6 or Freedom Fighter, too. I can think of no cons with this knife.

Great indestructible fighting/utility knife
After being issued this knife in the marines, I fell in love with it's durability and solid feel. I had the same one for an entire four year enlightenment and through countless field training ops and two combat deployments. I have put the thing through the most punishing abuse and stress one would dare to put any piece of gear through and it has been exposed to the most harsh of elements and weather and still remained very usable. It did become a little dull after the first couple of training ops but sharpening it is fairly easy if you know what your doing. It remained a great tool until the very last time I had to turn it into the armory and I'm confident it is still in faithful use buy another abusive Devil Dog.

I did not believe the Marine Corps would ever improve on the KA-BAR but it has. I like the balance, the length, and its ability to keep an edge. Even members of the Ol' Corps would approve this knife.

The Best Bayonet/Combat/Utility knife Produced
I cannot say enough good things about this Combat knife. It has to be THE BEST military issued knife since the original Kabar. I have sharpened and honed mine to maximum sharpness and has stayed that way doing activities all day with it sheathed on my hip, (must be the hytrel polymer sheath) because other polymer sheaths tend to dull the blade as been my experience like with a kabar hard plastic sheath. I use this knife daily and still razor sharp. Ive also dropped this knife a few times and still, no damage. I've seen Marines train with this knife, and if this knife can withstand damage and abuse even from the most clumsy guy in the Marine Corps, then I know it'll withstand all that I throw at it. It has about an inch and a half of serrations which I don't like but I don't use it, so it stays very sharp for emergency purposes only. I only use the top portion which is how you're supposed to be using a knife anyway. I love this knife and I would love to hear stories of Marines in Combat using this knife. This knife will be legendary just like the original Kabar. What can I say. It's my favorite knife and I carry it everyday everywhere because the crime rate is ridiculous here. I use it at work (my bosses are really cool like that!) I use it at home, I use it out in the field and it just keeps going. Dont debate on whether or not to get this knife, JUST GET IT, it will serve you well, you will be impressed!!

Much better than expected
This blade far exceeded my expectations. I am not impressed by most bayonets, however Ontario hit this one out of the park. First impression is that this is a hefty knife. I was worried that when I got it in, it would be somewhat flimsy. Once I got it in hand, however, all fears disappeared -- this is a hard use, no excuses blade. Fit and finish are perfect. No gaps, no molding flash on wither handle or scabbard, all stamps are clear and sharp and all moving parts and snaps are crisp and tight. I am also impressed with the sheath. It is not flimsy in the least. All of the stitching is tight, the plastic is hefty and it has a spring steel retainer in the sheath to keep the blade from falling out or rattling around, even if you leave the straps loose. A lot of thought and attention to detail went into this knife. Function wise, it is a very useful general-purpose knife that also serves as a bayonet, which is important on today's battlefield, as you don't have room for a tool that is only good for one thing. My only knock is that the blade (including the swedge) came sharp, but not real sharp. However, they steel is hard enough to hold an edge, and soft enough to easily take an edge, so this isn't a problem. Just don't expect to shave with it out of the box.

Impressive!
I find it a bit odd trying to review this blade as I have not yet had the opportunity to actually bayonet anything with it so I can only speak of the overall quality. The design of this bayonet is very impressive, probably the most imposing US bayonet since 1905. I like the thickness of the blade, it seems sturdy without being heavier than neccessary. I also like the tip configuration but I'm not sure I like the furthest 3 inches of the spine side of the knife sharpened or not. The serations are well executed but I would have prefered about 25% less of them. The handle is very comfortable to me, and its material seems a touch "grippier" than the kraton that comes on the Ontario spec plus lineup. The scabbard seems very well designed too, with excellent blade retention and a sharpening rod attached. The fit and finish appears superb, the edge is the same across the entirity of the blade and comes sharp from the factory. I actually cannot find anything to complain about this product, perhaps after much hard use, but I doubt it. Ontario did an excellent job of ensuring that all thought out requirements were well executed in manufacturing. Overall I think this is the best M16/AR15 bayonet available now, and I would choose it over my M9 and M7 if I could only have one.

Excellent Survival Choice
I bought this bayonet to use as the main survival knife in my bug-out-bag and as such I hope that I never "have" to use it. I did use it to construct a fire making bow drill so it was used for everything from light whittling to moderate batoning. This knife appears to be nearly indestructable and mine stood up to a pretty good beating with a hickory stick with no damage at all. Though I hope I never have to "fix" it to a weapon I did choose the bay-o-net for the ease with which it can become a spear in a survival situation. The knife arrived with a sharp edge and after the above use a couple of licks on a hard arkansas and a leather strop had it shaving sharp. It is a rather large heavy knife but it suits my needs perfectly and the molle sheath works with my bag.

USMC Bayonet & Scbbard
I was very impressed with this knife. It is a hunting, camping and a work knife that happens to be a bayonet, It comes with an excellent edge, not razor sharp although you can make it so with a little time. The blade is strong and heavy, the handle seems to fit everyone's hand like it was a custom job. I also like the way the sheath is made. You can put the knife in for either a right or a left handed draw. It fits well with any of the AR type rifles that have a bayonet lug. The lug clasp is tight and seems well made. I think so much of this bayonet that I will be buying a few more for Christmas presents this year. For the money, I do not believe you will find a knife of this quality anywhere. As a former Marine, I will probably retire my KA-BAR and carry this one instead.

For its intended purpose and as a general field knife it does very well. Splits small timber - long enough to bash it through. I was pleasantly supprised as it was much lighter than I anticipated. Tool steel and great grip matierial when wet, and the sheath is outstanding. Made in USA!

Makes me want to reenlist! A truly sharp fighting knife, bayo and survival knife with the sheath and hone rod to help. This is a great add for the emergency bag. I'd say packing this in your Maxpedition Sling Bag with the new Ontario Air Warrior (massively improved pilot's knife), a 1911 .45, Lifeboat Bars and spare buckshot! This knife could easily command $200.

Best Bayonet
This knife is the best of the currently available US milspec bayonets, its full 8 inch blade far exceeds all the others. It's the ultimate camp knife, utility knife, and will fit all milspec NATO bayonet mounts in addition to its inherent utility. Get one. It will need a final sharpening after you have it.

This a serious fighting tool, feel very balanced in my hand. Great, strong blade, fairly sharp out of the box. Very sturdy, professional scabbard. The built-in sharpener could be "rougher" to match the blade. Love everything about this knife.

This is a Best of Breed Blade & Scabbard
It's longer, stronger and has a better grip than my M7. My step-son is a Marine Reserve and if he doesn't have one, I'll give him mine and buy another. It's a bit heavier than my M7, but the bigger blade with the serrated edge will make this a better all around cutting tool at the campground. Even the scabbard is a high quality, well designed and solid way to carry this bayonet safely. I agree with all of the other reviews that the overall quality, finish, and materials made in the USA are the Best of Breed and worth the price.

New USMC Bayo
This new fighting bayo may be the best design I've ever handled. Decent steel, excellent weight and 8" blade profile, great rubbery plastic grip, combo blade... As an all-purpose tool this is a nice knife that goes into a nice sheath and happens to fit a bayo lug. I gave it a 4 only because I had to return mine as the cross-guard wasn't touching the blade by a good 1/8". I KNOW the replacement will be a 5.

pre-review of bayo-knife
This is only the second bayo-knife I have seen for my ARfiteens. The other was by ZT, a LOT more expensive and no longer available. My main issue is with the grip-heavy weight distribution- it's a little off balance, but probably to be expected in a knife that isnt designed to be a chopper. NO doubt that it is a slicer with a proper knife-edge honed into the blade. These knives will be used for opening boxes, crates, cutting rope, line, wire.. Steel seems to be a 1095 Carbon, or something very like it. Perhaps the temper is drawn down a little to make for a stronger blade, not sure on that. This will be a general purpose knife serving as a pig-sticker too, attached to my duty belt or pack. There is a Vietnam-era bayo in my collection, a thin, daggerish thing. This KNIFE bayo is miles ahead of any of that style. Carried a USMC KaBar years and years ago.. this weapon/tool is years ahead in that it is both a knife and a useful bayo that won't be left behind. IMO, YMMV!
