A Practical Screw

Who wouldn’t like a screw…umm screwdriver that’s practical! The Big O in this concept is that its offers better grip, with the handle swiveling a cool 90 degrees to stand perpendicular to the metal shaft. Now if you want to read a deeper meaning to this post, be my guest…because phrases like “force can be applied with a much stronger grip” and “toughest screws can be tightened more easily” makes me think of double meaning stuff!

    This “switch” concept is not really a concept at all, its a reality, and I have one.

    I have a screwdriver that is probably 20+ years old, and it swivels to be perpendicular to the handle for added leverage just as this one does. The one I have has a metal handle as well. Its a nice design, but old technology 😉 Anyone remember the ratchet ball screwdriver kit, you could interchange the tips and length of the shaft.

    ‘enormous losses to life and property’ from screws that aren’t properly screwed in? thats a bit over the top isn’t it?

      ROFL! thats like super worst case scenario. something that would appear on final destination or something XD

        haha awesome, It’s funny the scenarios people invent to help push the product. As a student I was guilty of it to a lesser extent, I think it helps having news articles or reliable sources to help back up the statements and convey the products importance.

        Would love to see the final destination styled TV ad to market the product!!

    It’s an old technology. It’s a great idea, sure. But it’s been done before.

    That’s like posting the rubber tire on Yanko because it’s such a great idea. Well, yeah, but…

    And seriously? sexual innuendo is not professional.

  • David says:

    Brennan, sexual innuendo is only ‘not professional’ because you have a politically correct expectation of corporate enterprise which you therefore also apply the expectation of to smaller design firms and the blogs they run.
    Take your hand off your proverbial penis and realise that it’s not against the law for companies to have a sense of humor, it just means they may not be particularly targeting a broader ma&pa market, which, if it’s just a concept, doesn’t matter.
    Ma & pa also aren’t going to be reading this post, so it’s not like they’ve compromised anything in that way.
    I think it’s great that people are caring less about political correctness, from the small players to the big ones; the virgin empire is a fantastic example of that.

    Also a fantastic design, even if it has been done before, I haven’t seen it with the rotating cuff to secure the screwdriver in, in the parallel position.
    Good artists create. Great artists steal.

    This tool is already made by a japanese company

    Practical Screw-Driver. I have gotten the same effect by putting an adjustable wrench on the side of a typical screwdriver, but typically the head of the screw is not made to take the force and the slot or phillips center metal peals away leaving a mess to try to remove.
    For those stuck bolts I like to use an Impact Screwdriver.

    Works like a typical screwdriver, but you put just a mild counterclockwise force on the tool, then rap the back of the tool with a hammer. The tool then matches the downward force with a rotational force preventing the slot or phillips center from rounding out.
    Motorcycle engines are put together with SCREWS!!! Even holding the engine casing and transmission together. Marine engines also use a lot of screws. I have never been without an impact screwdriver to remove these little buggers. The took can also be used to tighten these screws, but be carefull, since you can snap the screw before the head will round out.

    is it not risky when you use it to drive electric related appliances and gadgets…metals connected to elec?

  • Scudwerth says:

    joe has it right.

    Typical screws aren’t manufactured to take the kinds of stresses that you can apply with the extra leverage. Perhaps a nut driver.
