Bergo Tools ergonomical knifes on scientific bases
Work realted Musculo-Skeletal Disorders MSD's constitute the largest job-related injury and illness problem in the United States today.

"Employers pay $ 15 - 20 BILLION in workers' compensation costs for MSD's every year."

Source Ergonomics Program - Department of Labor - OSHA - Nov 1999
"California OSHA has noted comparatively high injury rates in agriculture and designated it a targeted high risk industry. Moreover, thease rates help explain why we see so few workers performing these jobs beyond age 35."
What is ergonomics?
Ergonomics is a science that stucies and measutes how we interact with the objects we use and the environments we live in. Its aim is to improve the comfort and efficiency of our lives, with particular attention to health and safety.

  • Do we need ergonomic hand tools?
    Over the centuries mankind has used tools to accomplish countless objectives in agriculture and industry. While many tools have evolved into efficient instruments with specitic uses, other tools have remained virtually unchanged since industrial revolution.

    The goal of ergonomics.
    The goal of ergonomics is to maximize emploee comfort and job satisfaction in order to obtain maximum employee productivity.

    What causes Cumulative Trauma Disorders?
    A combiantion of three main factors: Force, Repetition and Bad Posture, can cause sudden inuuries such as Sprains or slow developing injuries like Bursitis and Carpal Tunnel Syndrome.

    The highest risks are encountered when a job or tool requiring a combination of force and precision is used repatedly without sufficient rest for the body to recover


    The cost of ignoring ergonomics.
    As industrial work places become genereally safer and violent accidents decrease, more attention is being drawn to injuries that develop slowly.

    Musceuloskeletal Disorders (MSD's) as they are known, have emerged as a major cause of industrial injury. MSD's not only cause and disability to the sufferer, they also cost indystry increasing amounts of money in lost production, sickness, insurance and legal penalities.

    The need for user friendly hand tools that decrease the risk of cumultative injury is clear.

    New type of knives grips
    The handle shape is based on the nine types of knife grips that are used in professional butchering work.

    Work related illness.
    Cumulative Trauma Disorder (CTDs), Repetitive Strain Injuries (RSIs) and Occupational Overuse Injuries (OOIs).

    The three conditions listed above are various types of work related musculoskeletal disorders.

    These disorders result in many more specific conditions such as: tenosynotitis, tendonitis, apicondylitis (tennis albow) and the most frequently reported of all disorders, Carpal Tunnel Syndrome. Carpal tunnel syndrome results from damage to the median nerve at the wrist, this tends to disrupt the functioning of some of the 17.000 pressure sensitive nerve endings in the hand.

    As the hand is repeatedly opened and closed, the tandons that work the fingers can rub against and inflame the sheats through which the nerves pass. This causes them to swell, which creates pressure within the confined tunnel space in the wrist.

    The result is loss of hand function (numbness, tingling and pain). The base of the thumb and index finger, the mid finger and parts of the ring finger can loose the ability to grasp, hold and manipulate.

    Spezialised jobs, repetitive tasks and excessive forces combine with poor posture to make these problems a particular risk of the modern, high production workplace. The situation is made worse by the fact that not enough rest can be taken to allow the body to properly recover.

    Bergo ergonomic knives combat these tendensies in a direct way, by reducing the effort and stress of repetitive industrial tasks and, where's possible, improving posture.



    Tendon sheaths.
    The tough and gristly tendons transfer muscle movememnts to the bones through sheaths lubricated by synovial fluid. With over-use the sheath can become dry causing friction and inflammation. It can also be flooded with synovial fluid causing ganglionic cysts.


    The carpal ligament
    The carpal ligament is a band of tough tissue that encircles the wrist. The finger and thumb tendons pass through lubricated sheaths beneath this flexible protective cover.


    Carpaltunnel Syndrom
    When the hand is opened and closed in the relaxed neutral position the tendons slide easily through the sheaths at the wrist. As soon as the hand is angled, however, the tendons are squashed into a smaller space and the risk of friction dramatically increases. When friction inflames the tendon sheaths, they swell and put pressure on the median nerve which runs through the same tunnel space. This, in turn, causes pain and problems in the hand itself. Rest is then required to allow the initial inflammation to heal.
