Universal Design for Hammer

Not much of a carpenter, but sometimes we do get stuck in a situation where we need to tackle the nail, the bang, our fingers …all at one go. Desperate times call for desperate measures and the Unihammer is a likely solution. The design of the hammer is such that it increases the target area considerably. Simply place the nail underneath the detachable head and hold it in place. Next, strike the detached head with the hammer, and you my friend have saved your fingers AND embedded the nail into place.

The Structure:

The structure of UNIHAMMER is rather simple. A steel piece that can withstand the force of a hammer is used to fasten the nail in position. Using a piston mechanism to raise it up and down, and the frames on both sides keeps it perpendicular. The user is able to hold the nail perpendicularly without having to place their fingers anywhere near the nail itself, reducing the risk of hammering himself.

    Superb idea! Would really save us DIY guys a lot of unnecessary pain. =P

  • keekstar says:

    …but you would still have to hold the detachable head in place???

  • Jay-z says:

    can we also have vibrating hammers?

  • J Dizzle says:

    Interesting, but a nailset or ramset really does the same thing. Plus you can see what you’re doing. the nail is hidden by the giant cannister here so how do you know when it’s “in and flush” without overhammering your surface?

  • antgoo says:

    I agree with J Dizzle. Plus, what’s to stop you from accidentally punching a canister sized circle in your wall when you hit this thing at the wrong angle?

    It’s a good idea, but it needs more simplicity.

  • Here is a old old old trick, take your nails (1-2-22-222, whatever)and push them into a piece of paper or a “dryer sheet” (you know the ones that you toss into the clothes dryer that has softness on it) now use that to hold and position the nail. Hit the nail, yank on the paper or foam strip and do it all over again. This works great, you can see where your placing the nail and you can zip right along at a good clip unlike the proposed device.

    You all need to go back to school! Seriously.

  • esie says:

    well i guess you better learn how to hold the nail instead of making something to forget about it and honestly you might find different size of nail which won’t be fit to be used by this tool. i mean the length of the detachable piece is not enough what if the nail is too long for that. also you have to come up with an idea for adjustment the nail in exact position, well like putting signs on minor and major axises or whatever. design is a stylish and it’s just the only thing i like the solution’s got many defects.
