Redesign the Kitchen Knife

Designer Jongwoo Choi believes traditional knives are not suitable for elderly because the center of mass is located at the rear when people push down. His solution – the Swing Capsule kitchen knife. The handle can rotate up and over the blade creating a more centered balance while keeping your fingers safely away.

    Very nice! Tell us when it comes out!

  • Interesting, but the mechanics of it create two challenges which are unresolved:
    1. reduced feel for where the blade is due to indirection from the handle. This reduces precision and increases risk of sliced guiding fingers.
    2. greater blade wobble due to lateral forces. This reduces precision and increases risk of sliced guiding fingers.

    Cheers,

      Agreed, not for the real chef's out there.. more a mass market chopper idea, will not last long.

    • Cra says:

      Exactly what i was thinking. Blade would surly wobble more with your control hand higher up, especially when cutting tough stuff. But nice concept none the less

    I was at the National Museum in Stockholm in April and there I saw something like this…and it looked like it was from the 70s or something so not much new here

    I've to test it, but looks an interestign idea despite I'm not totally agree with the concept of disassemble the handle

  • Alex Rivoli says:

    Whenever you want to disassemble and wash the knife you must touch the blade and grab it hard. This can be extremely dangerous.

    There might be a reason the knife has kept the same design for countless centuries.

    I am not at all persuaded that this solves a problem, because I'm not convinced that the problem exists. I think people should simply learn how to use a French knife.

    First, the illustration shows hand positions liable to cut one's thumb.

    This only allows you to push/mash the knife into whatever you are cutting. While fine for some things, if you ever need a different cut, this knife suddenly becomes more dangerous as the heel will not be planted on your cutting surface.

    One of the reasons for different knife shapes – you move the center of mass.

    Finally, I imagine gripping the knife handle is a more applicable reason as to why the elderly might have trouble using any sort of knife. Wrapping your hand around a handle as shown looks quite painful for those with joint pains, arthritis, etc.

    A project that seems to be done just all digitally. If you've tested out with any physical mock-ups you'll immediately find out how wobbly it makes and lack of precision when the handle is on the top position like the concept.

    interesting concept. but when you are trying to redesign something as old as a kitchen knife, one must do further research into it and understand the history and its mechanics.

    There are issues of
    1. balance
    2. sanitary
    3. weight and handling

    although this is interesting concept, this is as useless fad as a salad chopper 2000.

    컨셉은 새롭지만, 주방칼과 같은 역사가 깊은 도구는 많은 조사와 사용에 대한 깊은 이해가 필요합니다.

    모양이 이쁜것도 중요하지만, 무게 밸런스와 실제로 사용될때 간단해야 하는 이유가 있기때문이죠.
    잠시 사용하는 쓰고 버리는 물건이 아닌, 좀더 깊은 리서치를 통해 향상된 디자인을 기대합니다.

  • I want to thank all of you for your comments and advice. I will try to improve exact solution. ^__^

  • No Tang? 'T ain't right I tell ya'.
    Definitely would be harder to wield as a kitchen apparatus, though it seems that it would do well in a fight…
    also, if that yellow substance is plastic it will likely break leaving you with a useless blade that would be hard to re-purpose… Which is why blades are made with a tang, so you can simply fix the handle. I personally will never pay for a blade without a full tang, Then again I only ever need a 5" Santoku

    hi, what is the software that you have used to design the kitchen knife ??

  • Rafaela says:

    Hi colleagues, its enormous post concerning educationand fully explained, keep it up all the time.

  • Leslee says:

    Do you mind if I quote a few of your articles as long as I provide credit and
    sources back to your website? My blog is in the
    very same niche as yours and my users would really benefit from some
    of the information you present here. Please let me know
    if this alright with you. Many thanks!
