15 Knives with Unique Opening Mechanisms

Copy-paste from here

1. Kershaw ET

The Kershaw ET uses a toggle mechanism to open and close the blade. You can actually engage the blade through many ways (using your thumb like a traditional folder and dropping the handle while holding the blade), but the toggle is probably the most fun. You can use a lever near the butt of the handle to open and close it. The knife was discontinued, probably because there’s the danger of the knife closing on your thumb when you use the toggle.

2. CRKT Rollock

To deploy the blade, you press down on the blade (specifically on some jimping near the rear of the spine) when closed. That pops the blade up, and then you slide it completely open.

3. Paragon Knives by Asheville Steel Warlock

With the press of a button, the handle opens up (think Moses parting the sea) and you use gravity to take it home. The same thing goes for closing it. When the handle parts, the blade slides back inside. You’ll want to make sure the knife is held the right way or your palm could be in for a rude surprise.

4. Scorpiodesign Shapeshifter EDC

Basically, as the tip of the knife travels through the butt of the handle at an angle, the middle portions folds into itself and the snaps into place. I’m not doing it justice in my description. The knife is meant to be a great EDC knife, but it seems like it would take a lot of time getting used to it.

5. CRKT Fulcrum 2

When the left side of the frame is pressed with the thumb, the blade swings open about 90 degrees. When the left side of the frame is pulled back, the blade opens the rest of the way. The cool part is that when you’re opening it, you can see part of the inside of the knife.

6. Schrade Viper Side Assist

When closed, one side of the handle shows the blade waiting inside; the other has a peculiar hole toward the top. To open up the knife, you simply push the blade through the hole until the spring assist activates and sends the blade hurling open.

7. A.G. Russell Funny Folder

The design is actually fairly old, more than 50 years old to be exact. To deploy the blade, you push the handle from the side while holding the frame (not unlike the Schrade Side Assist). Once the handle is fully opened, you pivot part of it back to reveal the blade.

8. Lone Wolf Defender

One way to open this knife is to hold the pivot between your thumb and index finger with the handle pointing upward. When the pivot is depressed with your fingers, the blade unlocks and the weight of the handle will cause it to fall, revealing the blade. To close it, you do the same thing but in reverse.

9. CRKT Snap Lock

his is another in a line of folders that open from the side. To engage it, you use your thumb to depress the thumb wheel and open up the blade. There is a thumb wheel on each side for ambidextrous opening.

The big advantage of the Snap Lock is that it opens from the side, meaning when you’re applying pressure to the blade, it is less likely to fail.

10. Smith & Wesson Power Glide

The blade does come out the front of the knife, but the fun part is getting there. When you pull the closed handle apart, it’ll reveal two aluminum crosspieces that connect to the bottom of the blade.

The farther you pull the handle apart, the more the blade comes out of the top. Once it gets halfway, you’ll have to give it a little nudge and then when it closes, the blade comes out the rest of the way. Then the handle locks up at the bottom.

11. Pacific Cutlery 983 Barry Wood

The Pacific Cutlery 983 Barry Wood is pretty close to a balisong because Barry Wood’s interesting swing lock pivots the handles open to reveal the blade. You essentially rotate one of the handles all the way around. In the process, the blade locks open.

12. Fox Knives aX Dobolock

To open this bad boy up, you press the top of the handle to make it open up from the bottom. Once one side of the handle is completely open, you whip your wrist to get the blade back up to the top. Then you snap the handle shut again in a swift motion.

13. CRKT Hole in One

The Hole in One has an open design with no enclosed handle. The knife is designed by Tom Hitchcock and is very similar to the CRKT Snap Lock by Van Hoy. It opens from the side.

14. Camillus Dominator

When the knife is closed, a protective mechanism covers the blade, making it safe and easy to carry. To open it, you press down on a notch and pull the cover mechanism back to reveal the edge of the blade. This is unlike most of the others on this list, but it’s an interesting design that I hadn’t seen before.

15. Fred Perrin Le Tri-Folder

Then you open it up and swing the blade back inside. This is similar to the Cold Steel Triple Action Folder that came out some time later (and has been subsequently discontinued). It does take some getting used to, but once you do, you could have the knife open and ready to go in an intimidating second.
