It is a pocket sword. Honestly, there is no other way to describe the Cold Steel Rajah 2 without sounding like you’re exaggerating for a YouTube thumbnail. When you first hold it, your brain does a little glitch. It’s too big. It’s too heavy. It looks like Andrew Demko decided to take a traditional Nepalese Kukri and figure out how to fold it into a pocket. And somehow, it works.
Most people see this knife and laugh. I get it. Who needs a folding knife with a six-inch blade that weighs nearly a pound? But once you get past the initial "mall ninja" vibe, you realize this thing is a masterpiece of engineering. It’s not just a novelty item; it’s a tool designed to take a beating that would snap most other folders in half. It’s the kind of gear that makes you look for things to chop just to see what it can do.
The Kukri DNA in a Folding Frame
The heart of the Cold Steel Rajah 2 is its blade shape. The Kukri is legendary for a reason. That forward-leaning weight distribution makes it a chopping machine. Normally, folders are terrible at chopping because the pivot point is a massive structural weakness. If you try to chop wood with a standard folding knife, you’re basically asking for the lock to fail and the blade to close on your fingers.
Andrew Demko, the designer, solved this with the Tri-Ad lock. It is arguably the strongest locking mechanism in the world. Instead of just a leaf spring or a liner, it uses a stop pin to redistribute the pressure of an impact away from the lock bar. When you hit something hard with the Rajah 2, the energy doesn't just crush the lock; it gets soaked up by the entire frame of the knife. It feels like a fixed blade. Seriously.
The blade itself is typically made of AUS-10A steel these days, though older versions used CTS-BD1 or AUS-8. AUS-10A is a solid choice here. It’s tough, holds a decent edge, and—most importantly for a chopper—it isn't so brittle that it’ll chip the first time you hit a knot in some oak. The stonewashed finish is also a nice touch because it hides the inevitable scratches you’re going to give it.
Ergonomics of a Giant
The handle is Griv-Ex. It feels like a very hard, textured plastic. Some people hate it because it feels "cheap," but those people usually aren't using the knife for its intended purpose. If you're swinging a six-inch blade, you want grip, not fancy polished wood. The deep finger choils allow you to "choke up" for fine tasks—like, say, whittling a spear—or grip it at the very end for maximum leverage while chopping.

It’s huge. It’s nearly 14 inches long when open.
Carrying it is... an experience. It has a pocket clip, but you need deep pockets. And strong pants. If you’re wearing thin dress slacks, the Rajah 2 will literally try to pull them off your waist. But in a pair of Carhartts or heavy jeans? It disappears surprisingly well because of how flat it is.
Does Anyone Actually Need This?
Let's be real. If you’re just opening Amazon boxes, the Cold Steel Rajah 2 is total overkill. It’s like using a chainsaw to cut a sandwich. But that’s not who this is for. This is for the person who wants a "just in case" tool.
I’ve seen people use these for clearing brush on a trail when they didn't want to carry a full-sized machete. I’ve seen hunters use them as a backup tool for processing large game. There’s also the self-defense crowd. While I’m not an expert in knife fighting, the sheer intimidation factor of a Rajah 2 snapping open is probably enough to end most confrontations before they start.
The "Wave" feature is a big deal here too. There’s a thumb plate on the top of the blade. As you pull the knife out of your pocket, that plate catches on the hem. The blade swings open automatically as it clears the fabric. It makes a sound like a car door slamming. Thwack. It’s one of the most satisfying mechanical sounds in the gear world.

The Learning Curve
You have to learn how to sharpen this thing. Because of the recurve (the "S" shape of the edge), you can’t just run it across a flat whetstone. You’ll need a rod-based system or a narrow stone. If you flatten out that curve, you ruin the chopping physics that make the Kukri shape work.
Also, watch your fingers. The blade is so heavy that when you disengage the lock, it wants to drop like a guillotine. Always use two hands to close it until you’ve developed the muscle memory. I’ve seen more than one "expert" get a nasty bite because they thought they could flick it closed like a little Bugout.
The Competition and the Market
There aren't many knives that compete in this specific weight class. You have the Cold Steel Espada XL, which is even bigger but more of a "saber" style and less of a workhorse. Then there’s the Spartan Blades Harsey Folder, but that’s a completely different price bracket.
The Rajah 2 sits in a weirdly perfect spot. It’s usually priced between $100 and $150. For a knife this size with a lock this strong, that’s actually a bargain. You’re getting a lot of steel and a lot of engineering for your money.
Some critics point to the weight as a downside. It’s roughly 13 ounces. For the "ultralight" hiking crowd, that’s a nightmare. But for someone who values durability over everything else, that weight is reassuring. It feels like a tool you could give to your grandkids.

What to Check Before Buying
If you’re looking to pick one up, keep an eye on the steel markings. While the AUS-10A is the current standard, you might find old stock in AUS-8. AUS-8 isn't bad, but it doesn't hold an edge as long as the 10A version.
- Check the Pivot Tension: Out of the box, they can be a bit stiff. A drop of KPL or 3-in-One oil works wonders.
- Inspect the Tri-Ad Lock: Ensure there’s no "lock rock" (movement). Cold Steel’s quality control is usually great, but with a blade this big, any play in the lock is magnified.
- The Pocket Clip: It comes with a left and right-hand clip in the box. Make sure you use the right one, or the Wave feature won't work correctly.
It’s easy to dismiss the Cold Steel Rajah 2 as a toy for people who watch too many action movies. But once you use it to limb a fallen branch or realize it can do the work of a small hatchet while fitting in your pocket, you get it. It’s a specialized, over-built, slightly insane piece of cutlery that refuses to apologize for what it is.
Putting the Rajah to Work
If you actually plan on using this for more than just a conversation piece, start with some light backyard testing. Chop some 1-inch thick saplings. Notice how the recurve "grabs" the wood and pulls it into the cut. It doesn't glance off like a straight-edged knife often does. This is why the Kukri design has survived for centuries.
Don't be afraid to use the thumb plate for more than just opening. It acts as a great place to put your thumb for extra pressure during a controlled cut. Just remember that this knife is a force multiplier. Because of the weight and the sharpness, you don't need to swing it as hard as you think. Let the tool do the work.
For long-term maintenance, keep the pivot clean. Since it's a folding knife used for heavy tasks, dirt and grit can get into the locking mechanism. A quick blast of compressed air every now and then keeps the Tri-Ad lock engaging deeply and safely.
Ultimately, the Rajah 2 isn't for everyone. It's for the person who wants the maximum amount of "knife" they can legally carry. It’s for the person who appreciates a design that pushes the boundaries of what a folding tool can actually handle. It is loud, it is heavy, and it is absolutely effective.
Practical Next Steps
- Test Your Pockets: Before buying, ensure you have pants with reinforced pocket edges; the Rajah 2's clip and weight will shred thin fabric over time.
- Invest in a Sharpener: Pick up a ceramic rod or a Spyderco Sharpmaker to handle the recurve blade, as standard flat stones won't reach the "belly" of the Kukri shape.
- Practice the Draw: Spend time practicing the "Wave" opening in a safe, secluded area to get a feel for the tension required to deploy the blade without fumbling.
- Check Local Laws: Ensure a 6-inch folding blade is legal in your jurisdiction, as many cities have strict limits on blade length for "everyday carry."
