Spring-loaded bladed hand tool

Abstract

A force reducing bladed hand tool designed to allow the tool's blade to rotate so that the working edge of the blade is continuously aligned for optimal cutting or scraping with each arm movement. In the first embodiment, the hand tool is a knife with a hollow handle with a longitudinally aligned tension spring located therein. Mounted on the distal end of the handle is a connector with a downward extending spline attached thereto. Pivotally attached to the spline is an elongated blade with a cutting edge. The proximal end of the blade is attached to a coupler which connects at an opposite end to the spring bias the blade inward through the connector and towards the handle. During assembly, a pivot pin is extended through the bore in the spline and a complimentary bore formed on the blade. The pivot pin and the lower slot on the connector enables the distal end of the blade to pivot upward when excessive pressure is exerted on the handle by the user's hand.

1 . A spring loaded bladed hand tool, comprising:
 a. a hollow handle includes an opened distal end and a proximal end;   b. a rotating end cap attached to said proximal end of said handle;   c. a coil spring longitudinally aligned inside said handle;   d. a blade pivotally a connected to said distal end of said handle, said blade includes a proximal end and section that partially extends into said handle and rotates downward from said handle when sufficient force is exerted on the distal end of said blade;   e. means for coupling said section of said blade that extends into said handle to aid coil spring; and,   f. means for adjusting the tension of said coil spring connector attached to an over said distal end opening of said handle.   
     
     
         2 . The spring loaded bladed hand tool, as recited in  claim 1 , wherein said blade is an elongated blade with a lower cutting edge. 
     
     
         3 . The spring loaded bladed hand took, as recited in  claim 1 , wherein said blade includes two flat surfaces perpendicularly aligned and mounted on a rod that fits into said distal end of said handle.
