For those who don't know, this is the knife issued to Marine Corp & Army pilots during the Viet Nam War, it was designed to cut/ smash their way out of a downed aircraft to escape capture by the enemy. A veteran once described the toughness of this knife as follows...You could use this knife to dig your way through a brick wall & then attack a tank with it. Now that's my kind of knife!!! I am very,very satisfied with my purchase & did some special cosmetic work to my new knife. Colored & burnished the edgework all around the sheath, coated sheath with neats foot oil to darken it up, then burnished rough spots out of handle, then dyed the handle a nice rich burgundy leather dye, & burnished that out, put on a coat of neutral shoe polish & buffed that baby to a high gloss shine. It's a beauty I will treasure, as I am a vet that served at the end of that war but luckily was never sent there. My hats off to all that did go there, being a military history buff, I am very well aware of what many went through, especially the "tunnel rats" & the "LRRP 's" talk about balls of steel, they could not have done what they did without balls of steel !!! Thank you for the finest of USA made products,,, no Chinese knock off here!!!

Cuchillo Ontario knife Airforce
Nada más mítico
El mejor cuchillo que un hombre puede tener....mil por ciento recomendable....saludos

In 1969, A friend gave me a Camillus Pilot Survival Knife that had a thick blade with a blue like finish, and a concave edge, which could be sharpened to a deep cutting edge. I took that knife on many backpack excursions in Mexico. The Camillus knife was good for many tasks, which included among other uses, cleaning fish, wood processing for campfire, digging, and opening coconuts. While I had it, over the decades, that knife served well.
The Ontario copy has an abruptly beveled edge. I had to sharpen it for a long while to achieve an adequate sharpness, but it does not make deep cuts. Nonetheless, it functioned well enough for shaving wood off a Black Walnut (hard wood) bow staff. Setting its abrupt, angled edge to one side, the Ontario version seems tightly built, and comparable in strength to the former Camillus.
The metal reinforced sheath that comes with the Ontario copy is better, safer, than the all leather sheath issued by Camillus.
If you need a deep edge for better slicing, the Ontario copy is challenged. The low price is the deciding factor. If you need to budget for a general-purpose outdoor tasks knife, I think that the Ontario copy is good, enough, to rely on in a pinch.

I bought this knife and though saddened as I opened the carton when I received in the mail, it was also comical. Instantly viewing the handle and gently inspecting the blade, I knew this was either a counterfiet or the manufacturers were asleep as the automated machinery in the facity malfunctioned.
Regardless, I kept the knife and took it to my bench grinder to shape the blade into a blunt ended ice breaker or for self defense jabbing tool.

If this knife was made for survival, it fails miserably. Better suited for a hopeful survival but actually a realistic failure tool
