    This video was extremely helpful to me in understanding the ingenious mechanisms behind double-action switchblades. Thank you for making it!

      I somehow lost the password. I appreciate any assistance you can give me.

      @Ryland Zain thanks so much for your reply. I found the site through google and Im waiting for the hacking stuff now.
      Seems to take quite some time so I will reply here later with my results.

    So basically the spring tension (and allowing the "spring back") in either direction is what moves the blade. Thanks, this helped me understand. It also helps that the spring is not under constant tension when the blade is deployed, which should help with spring life

  • @olaftheviking14
    @olaftheviking14 12 років тому +1

    you kinda gotta watch it over and over. the latches keep the blade in place when its all the way in and all the way out. the casing (slider) slowly lifts the latches and moves the blade catches to build tension in the springs. once the slider moves far enough, the latch lifts all the way and the spring launches the blade forward/backward and is caught by the other latch to hold it in place. hope it helped and didnt just confuse you more! lol :)

  • @Orangespyder1219
    @Orangespyder1219 12 років тому +1

    @ cj the spring is being pulled further apart until the latch releases, causing the front or rear blocks to push the blade into the desired position. The spring is trying to pull two things closer.

    I want to make a custom OTF but I'm such a dumbazz that after watching like 20 videos on how tis thing works, only now I understood. Thanks, this gives me an idea on how to construct the mechanism.

  • @unbiasedreviews5978

  • @joerandom9489

    still don't understand how a 2cm spring tension can make a full blade length travel

    • @KarachoBolzen
      @KarachoBolzen 7 років тому +10

      it's just a strong spring,and moving the blade when the locks are disengaged is not that hard - think of pushing a metal ruler over a wooden table

  • @peterbread1993
    @peterbread1993 13 років тому +1

    @AmanEditing Imagine that either end of the spring (not for pushing, but for pulling) is attached to the two pink squares on the slider. When the slider moves forward, the spring stretches while the rear latch holds the notched blade in place, which stores potential energy. When the slider finally moves the rear latch away from the blade, the stored energy releases to kinetic energy, pushing the blade out. It works the exact same the other way.

  • @xmoroseguyx
    @xmoroseguyx 9 років тому +3

    The spring`s tension must dictate the blade length and thickness of the body, If the compression released does not have enough power it won`t make it down the body and catch on the blade catches

  • @MrSalty953
    @MrSalty953 13 років тому

    @quintincashman ...slider/switch unlocks the blade, releasing the tension on the spring, pushing the blade forward into the other set of locks, this happens vice versa, hope that clears it up a bit for you, took me a few days to understand the mechanism but when you look at it, it's a simple design, but works so well!

  • @ColtTenney
    @ColtTenney 13 років тому

    @Clayful1000 The purple boxes are the blade catches. Each one has a female slot that receives the male counterpart that's attached to the blade. The slots only allow the blade to go in and out of the catches one way.

  • @Josh-dr2xd
    @Josh-dr2xd 12 років тому

    the two spring catches are the only thing the spring is attached to... the blade is simply launched out and back from the handle, by the usage of the catches and spring pushing the blade to the locked position

    • @maximdrake
      @maximdrake 8 років тому

      the hidden blade mechanism is a little different because it is triggered with a string

  • @MrSalty953
    @MrSalty953 13 років тому

    @quintincashman Ok, so, the blade is locked in one position, by the locking tabs, and there's also some T shaped bars connected with a spring in the middle, when you push forward on the switch, one of the T bars is caught on the blade, which won't allow it to move, but the other T bar is free to move, so when the slide is pushed forward it will build tension in the spring because only one T bar can move (Because it's caught behind the blade, which is locked in place), and at last second the...

  • @Athorain
    @Athorain 12 років тому

    The case(green thing) has two notches, one for each catch. Those notches allow the catch to hold the blade and keep it from moving, until the green thing moves enough that the notch is no longer aligned with the catch. This means that the catch cannot be close enough to the blade and the spring is now free to push the blade.

  • @SubConcussiveSound
    @SubConcussiveSound 12 років тому

    on the knife there's a nub so to speak. B/C the knife is locked in its two positions the catches(the spring thingies)are locked,or, if you're talking about the latches (the things that pivot on a pin)then the same is(almost)true,the blade's notch has three faces, two square ends and a ramp, when the switch pulled the square face goes in the case and exposes the case's ramp, to make sure the blade doesn't get stuck b/c the latch comes down too fast when it is sheathing the blade has a ramp part

  • @baguetteboy5466
    @baguetteboy5466 3 роки тому

    So, is the blade attached to anything, or is it just the knobs that keep it in place? On a similar note, does the blade move by being launched from the force of the spring, or is it attached to something that moves it? Many thanks for whoever can answer.

    Because I doubt he'd have made it through the primaries with a platform of: "Elect me and I'll subvert all of your remaining rights because only I, and my friends, know what is best for you."
    Now that I think of it, that pretty much really was his platform. So, yeah. Templar in all but name.

      @TheBatlleAxeWarrior 5 років тому

      They double up the springs to save space, as I understand. Instead of having a single larger diameter tension spring, they have two smaller ones side by side. This makes for an easier package to fit between the handle scales.
