  • Patent number: 8616096
    Abstract: The present disclosure relates to a hand-held tool that may be held in the palm of a hand, the hand-held tool being of adequate length and size to allow users to comfortably transfer the tool from a palm grip to a pen grip to maintain the use of the fingers and the thumb when the hand tool is stored in the palm. The hand tool is also equipped with a retractable or nonretractable torque drive shaft designed to allow the fingers and thumb of a user to be rotated freely when the tool is in palm grip and capable of transmitting torque through the housing when an axial pressure force is placed along the drive shaft to engage the tool head with the housing.

  • Publication number: 20080178716
    Abstract: The present disclosure relates to a hand-held tool that may be held in the palm of a hand, the hand-held tool being of adequate length and size to allow users to comfortably transfer the tool from a palm grip to a pen grip to maintain the use of the fingers and the thumb when the hand tool is stored in the palm. One or several storage housings are attached offset from a drive shaft housing for improved torque transfer from a hand to the tool head, integral storage of work pieces, optimized use of palm torque during use, and better overall grasping. The hand tool is also equipped with a retractable or nonretractable torque drive shaft designed to allow the fingers and thumb of a user to be rotated freely when the tool is in palm grip and capable of transmitting torque through the housing when an axial pressure force is placed along the drive shaft to engage the tool head with the housing. The drive shaft can also be reversed to create a prolongation shaft or placed in another opening of the housing.
