HAND TOOL
First Claim
1. A tool comprising:
- a handle;
an implement pivotally connected to said handle;
a first magnetic element mounted on said implement having a magnetic field of a selected polarity intersecting a path disposed circumferentially relative to the axis of said pivotal connection; and
a second magnetic element mounted on said handle having a magnetic field of a polarity of one of the same or the opposite of said selected polarity intersecting said circumferential path whereby dependant upon the angular relationship of said handle and implement said magnetic fields will have the effect of one of a first interaction, producing no motive force for angularly biasing said implement relative to said handle, a second interaction, producing a repellant motive force for angularly biasing said implement relative to said handle and a third interaction, producing an attractive motive force for angularly biasing said implement relative to said handle.

Abstract
A tool generally consisting of a handle, an implement pivotally connected to the handle, a first magnetic element mounted on the implement having a magnetic field of a selected polarity intersecting a path disposed circumferentially relative to the axis of the pivotal connection and a second magnetic element mounted on the handle having a magnetic field of a polarity of one of the same or the opposite of the selected polarity intersecting the circumferential path whereby dependent upon the angular relationship of the handle and the implement, the magnetic fields will have the effect of one of a first interaction, producing no motive force for angularly biasing the implement relative to the handle, a second interaction producing a repellant motive force for angularly biasing the implement relative to the handle and a third reaction producing an attractive motive force for angularly biasing the implement relative to the handle.

24. A tool comprising:
-
a handle;
an implement pivotally connected to said handle for angular displacement between retracted and extended positions relative to said handle;
first and second magnetic elements disposed on said implement, angularly spaced apart, each having a magnetic field of a selected polarity intersecting a path disposed circumferentially, relative to the axis of said pivotal connection; and
third and fourth magnetic elements disposed on said handle, angularly spaced apart, each having a magnetic field of a selected polarity intersecting said circumferential path whereby dependant upon the polarities of said magnetic fields and the angular relationships thereof, said magnetic fields shall have the effect of one of a first interaction, producing no motive force acting to bias an angular displacement of said implement relative to said handle, a second interaction producing a repellant motive force acting to bias an angular displacement of said implement relative to said handle, and a third interaction producing an attractive force acting to bias an angular displacement of said implement relative to said handle. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51)

53. A tool comprising:
-
a handle;
an implement pivotally connected to said handle for angular displacement between retracted and extended positions relative to said handle;
one of said handle and said implement having a magnetic element; and
the other of said handle and said implement having at least a portion of a magnetically attractable material disposable within the magnetic field of said magnetic element whereby when said portion is positioned within said magnetic field said implement will be caused to bias angularly relative to said handle. - View Dependent Claims (54, 55, 56, 57, 58, 59)

60. A tool comprising:
-
a handle;
an implement pivotally connected to said handle for angular displacement about a first axis relative to said handle;
first and second telescopically connected actuating members, one of which is pivotally connected to said handle for angular displacement about a second axis relative to said handle, and the other of which is pivotally connected to said implement for angular displacement relative to said implement about a third axis radially displaced relative to said first axis; and
said actuating members having magnetic elements providing opposed fields of the same polarity whereby when said third axis is disposed on a first side of a line intersecting said first and second axes, said implement will be caused to be biased angularly in a first direction relative to said handle, and when said third axis is disposed on the other side of said intersecting line, said implement shall be caused to be biased in a direction opposite of said first direction. - View Dependent Claims (61, 62, 63, 64)
