Wire installing tool

In a tool of the type having a handle and being intended for use in attaching an insulated wire to an electrical connector, an elongated stem having a first end secured to the handle and a second end including a recess, and a blade mounted on the stem at said second end and aligned with the recess to form a cavity shaped to force the insulated wire into a conventional electrical connector, the connector stripping a section of the insulation from the wire core, said insulation section being displaced from the end of the wire, the blade having a cutting edge on at least one end thereof, the improvement comprising:

• said cutting edge of said blade having inclined outer and inner sides, the outer side of said edge being shaped for shearing the insulated wire and the inner side of said edge being shaped to cut the wire at a predetermined distance from said electrical connector so that a portion of the wire with the insulation in place protrudes past said electrical connector and has a kink formed in the protruding part of the wire core;
• a first surface on said blade outer side, said first surface being inclined at a first predetermined angle to form a cutting edge;
• a second surface on said blade inner side, said second surface being inclined at a second predetermined angle to define a space between said first surface and the stem wherein the protruding part of the insulated wire is formed;
• and
• said first angle being different than said second angle.
