Abstract:
1. An assembly for bending the blade of a drywall knife comprising a. a first blade bender comprised of a first upper arm wherein said first upper arm is comprised of a first threaded hole and a first threaded screw; b. a second blade bender comprised of a second upper arm wherein said second upper arm is comprised of a second threaded hole and a second threaded screw; c. a drywall knife comprised of a blade with a proximal side and a distal side; said blade being further comprised of a handle, a rigid rear blade section and a flexible front blade section, said rigid rear blade section being permanently connected to said flexible front blade section over the entire width of said blade such that the connection is fixed, said rigid rear blade section being contiguous with said handle; d. said first blade bender and said second blade bender are disposed on said blade such that said first blade bender is at said proximal side and said second blade bender is at said distal side; e. said first blade bender and said second blade bender are each comprised of a first section contiguous with, and flexibly mounted to, said front blade section and a second section contiguous with, and securely mounted to, said rigid rear blade section; f. said front blade section is comprised of g. said first threaded screw is disposed in said first section of the first blade bender and said second threaded screw is disposed in said first section of the second blade bender such that operation of an adjustable deflecting screw, selected from the group consisting of said first threaded screw, said second threaded screw, and combinations thereof, causes said adjustable deflecting screw to apply a force to said blade, causing said blade to bend such that the middle front point is deflected downward by a magnitude that is proportional to the force applied by the adjustable deflecting screw.
