1. A hand-held power tool for use in hand working operations, for use with a supply of pressurized fluid, comprising:

  • a body having a first and a second end;

    a tool tip holder at said first end for holding a tool tip;

    a hand placement location on said hand-held power tool for the user of said hand-held power tool to grip and hold said hand-held power tool during operation;

    a work energy means for supplying work energy to said tool tip;

    a variable fluid metering means for adjusting the amounts of said supply of pressurized fluid used for supplying varying amounts of said work energy means to said tool tip;

    a pressure sensing means for sensing the amount of pressure exerted by a human hand;

    between said hand placement location and said tool tip;

    said variable fluid metering and said work energy means will increase when pressure sensing means senses increased pressure; and

    said variable fluid metering and said work energy means will decrease when pressure sensing means senses decreased pressure.
