  • Publication number: 20080072430
    Abstract: An electronic palm-held hair trimmer has an ergonomically curved head with a trimmer housing that fits within a use's palm and fingers during use. The ergonomically curved head allows the user's hand to hold the hair trimmer in a manner that is generally perpendicular to the plane of the hair trimming mechanism during use. A detachable strap can be attached to clips on either side of the head for attaching to a use's hand to better support the hair trimmer. An On/OFF power button on the head is reachable by an index finger or middle finger of a use's hand while holding the hair trimmer in the palm of a use's hand. A turbo button is located with the power button, and allows for variable speeds of the trimming blades when activated. Attachments are provided for varying the amount of hair and length to be cut. The trimmer may be operated with a power cord or may include a rechargeable battery that is used as a power supply.
