Abstract

A handle system includes a body extending between a first end and a second end. The handle system also includes a slot extending, at least partially, in the body, the slot forming a cavity. The handle system further includes a carrier arranged, at least partially, within the slot, the carrier further comprising a friction locker and at least one arm coupled to the friction locker, the at least one arm being rotatable about the friction locker. The handle system also includes a cap arranged on at least one of the first end or the second end. The handle system further includes a blade coupled to the at least one arm, the blade being rotatable about the axis between a retracted position where the blade is positioned within the slot and an extended position where the blade extends outwardly from the body.

Claims16

Dependent claims

A method for using a handle system, comprising:

rotating a first carrier having a first arm and a second arm with a first blade coupled to the first arm, about a first axis in a first direction to transition the first blade out of a first cavity formed in a body of the handle system, the first carrier is coupled to the first axis;
simultaneously, transitioning a second blade coupled to the second arm into the first cavity of the body as the first carrier is rotated in the first direction;
blocking rotation of the first arm or the second arm beyond a predetermined position, by a rotation limiter proximate the first arm or the second arm and arranged within the first cavity,
rotating the first carrier about the first axis to cause the first blade to rotate in a second direction, opposite the first direction, to transition the first blade into the first cavity of the body;
simultaneously, transitioning the second blade out of the first cavity of the body as the first carrier is rotated in the second direction;
and
independently rotating a second carrier having a third arm with a third blade coupled thereto, about a second axis to transition the third blade out of a second cavity formed in the body of the handle system, the second carrier is coupled to the second axis.

4 more elements

A method, comprising:

selectively rotating a first carrier having a first arm having a first tongue and a first blade having a first aperture coupled to the first tongue of the first arm, about a first axis to transition the first blade between at least a first position within a first cavity in a body of a handle system and at least a second position extended outwardly from the first cavity of the body, the body has a first end with the first axis;
selectively rotating a second carrier having a second arm having a second tongue and a second blade having a second aperture coupled to the second tongue of the second arm, about a second axis to transition the second blade between at least a first position within a second cavity and at least a second position extended outwardly from the second cavity of the body, the body has a second end with the second axis;
installing a cap over at least a portion of the first cavity and the first blade when the cap is installed on the first end of the body or over at least a portion of the second cavity and the second blade when the cap is installed on the second end of the body;
blocking rotation of the first carrier when the cap is installed on the first end of the body and rotation of the second carrier when the cap is installed on the second end of the body;
and
during use, using one of the first blade and the second blade that is uncapped and extending outwardly to form a cut.
