Gear Review: Ontario Knife Company SK-5 Blackbird

Talk about a cool knife! The Ontario Knife Company’s (based out of Franklinville, NY) SK-5 Blackbird may be the coolest knife I’ve ever owned. Besides my hunting knives, most of the knives I own are smaller pocket knives so this is the first larger knife in my collection. I came across the SK-5 in this article from Field and Stream last year and decided I’d try my luck and add it to my Christmas Wishlist.  It is even featured here as one of the 20 great survival knives. Turns out, Santa thought this was a must have cause he got the elves to make me one.



The SK-5 Blackbird is a plain edge, fixed blade knife that is super sharp straight out of the box. It has a complete warranty covering faulty craftsmanship or materials used but does not cover abuse or neglect. The handle is made from Micarta (the best way I can describe it is that its some kind of fiberglass composite material). The SK-5 also comes with a MOLLE Compatible sheath made from nylon that is super easy to attach to your pack or hang from your belt. This knife just plain feels good in your hand as soon as you pick it up. The few times I have used this knife it has worked flawlessly. I haven’t put it through the ringer yet but I’m sure that day isn’t too far away.

  • comes with a sheath
  • very sharp
  • thick blade
  • balanced out well
  • Made in the USA


  • The only thing I found is the snap on the sheath sometimes is really hard to get undone but I’m cool with that as long as it keeps me from losing my knife

I would definitely recommend this to anyone that is involved in any outdoor activity from camping to hunting.
