Okay readers, here is the long overdue field review of the Ontario Blackbird SK-5 Survival Knife. We originally got the Blackbird in the middle of a major wildfire back in 2012, and due to everything going on at the time, we never posted the field testing part of the review. While digging through the RMB photo archives recently, I found the original field test photos from the Summer of 2012 and wanted to get them posted ASAP.
This review will focus on the Blackbird's development and performance. Rocky Mountain Bushcraft covered the Blackbird's technical features in our First Impression Review back in May 2012. You can check it out here.
Hedgehog Leatherworks Blackbird sheath:
Paul's unique retention strap system, along with his sheath's high quality, heavy duty construction, has made Hedgehog sheaths popular with world adventurers, military personnel and others who need maximum durability and reliability.
As Paul's reputation grew, he eventually caught the eye of famed New York survival knife company Ontario Knives, and teamed up with them in 2011 to create the Blackbird SK-5 Survival Knife, the subject of this field review.
Simplicity in Design
Paul's design turned out to be a big hit, earning the coveted Field and Stream "Best of the Best" Award in 2011. The Blackbird went on to become popular among Youtube knife reviewers, wilderness survival enthusiasts, and members of the prepper community.
Much has already been written about the Blackbird, but what I wanted to find out in my field testing was- 1) How does the Blackbird perform as a bushcraft knife and wilderness survival tool? and 2) How tough is it?
BatoningTo test the Blackbird's ability to handle batoning, I selected a log from the base of a branch on a large, old growth Ponderosa Pine. As I've mentioned in previous reviews, this stuff is the toughest, most twisted wood in the RMB test area, and has broken or bent the edges of several machetes and survival knives over the years. If it can handle this stuff, it can handle almost anything!
I call these 'evil' logs for a reason, and this one was probably the most 'evil' I'd found in a while:
As you can see in the photo, the Blackbird's blade was literally bending sideways while batoning through it:
The wood was so knotted and twisted, it only split into rough pieces. The Blackbird's blade was still straight as an arrow, and the edge could still shave hairs after this insane test-- wow.
Testing the spine with a Firesteel/Scraping Tinder
The Blackbird also throws mondo sparks from a firesteel, easily igniting these pitchwood shavings in the pouring rain:
Opening a Can/Testing Tip Strength
I used the tip of the Blackbird to open several steel vegetable cans at my base camp over the summer. There was no degradation of the edge, and the tip came out completely intact:
Steel Quality Observations
I've never hidden the fact that I'm a fan of Ontario Knives. I believe that for the money, they have some of the best steel and heat treat methods for survival knives. The Blackbird is no different. The 154CM used on it is very strong, takes a fine edge, and holds it very well. The only negative I could find is that like many 154CM blades, it can be a little harder to sharpen than typical carbon steel blades.
The nylon sheath is well constructed but a bit thin, and can flop around on the belt a little. However, it did seem well suited to its purpose during field testing:
The Blackbird's ability to do so many things well is probably its greatest asset. The blade's utilitarian shape makes it useful for nearly any task, from carving to batoning, food prep, or skinning game. The high quality steel is tough, yet takes and holds a great edge. The handle is one of the most comfortable I've used, and it fits a wide variety of hand sizes. Literally, the Blackbird is a "Jack of All Trades" wilderness survival knife.
Of course, all this doesn't come without a few caveats.......
The Blackbird's sheath is serviceable, but can flop around on the belt a bit. The good thing is that there are lots of aftermarket sheath options for the Blackbird, including Paul's own Hedgehog Leatherworks sheath.
The edge geometry could be improved slightly to make it better at carving feathersticks. One option would be to give it a convexed edge, or a slightly more aggressive V-grind.
One other minor issue is the Blackbird's chopping ability. Since it is weighted more towards the handle, it is one of the weakest choppers I've tested. It can handle light chopping, but shouldn't be counted on for heavier duties.
Overall, the Blackbird's pluses outweigh its minuses. The combination of its supremely comfortable handle, high quality, durable construction, and Ontario's history/lineage, make it a well rounded wilderness blade that's up to nearly any task.
