Abstract

A device comprising: (a) a first working arm; (b) a body; (c) a shuttle located on the body, and (d) a bias device; wherein the bias device biases the first working arm relative to the body when the shuttle is in a first position, and wherein the bias device is free of biasing the first working arm relative to the body when the shuttle is in a second position.

First claim

We claim:

1 ) A device comprising:
a. a first working arm; b. a body; c. a shuttle located on the body, and d. a bias device; wherein the bias device biases the first working arm relative to the body when the shuttle is in a first position, and wherein the bias device is free of biasing the first working arm relative to the body when the shuttle is in a second position.

2 ) The device of claim 1 , wherein the device includes a second working arm.

3 ) The device of claim 1 , wherein the bias device biases the first working arm towards the body when the shuttle is in the first position.

4 ) The device of claim 1 , wherein the bias device biases the first working arm away from the body when the shuttle is in the first position.

5 ) The device of claim 1 , wherein the bias device is located on the shuttle.

6 ) The bias device of claim 1 , wherein the bias device is located on the first working arm.

7 ) The device of claim 1 , wherein the first working arm includes one or more deactivation features.

8 ) The device of claim 7 , wherein the shuttle covers at least one of the one or more deactivation features when the shuttle is in the first position.

9 ) The device of claim 7 , wherein at least one of the one or more deactivation features are exposed when the shuttle is in the second position.

10 ) The device of claim 7 , wherein at least a portion of the bias device extends into the at least one of the one or more deactivation features that are exposed so that the first working arm is free of biasing when the shuttle is in the second position.

11 ) The device of claim 1 , wherein the bias device contacts the shuttle when the shuttle is in the first position.

12 ) The device of claim 1 , wherein the bias device is free of contact with the shuttle or the first working arm when the shuttle is in the second position.

13 ) The device of claim 1 , wherein a gap is located between the bias device and the shuttle or the bias device and the first working arm when the shuttle is in the second position so that the bias device is prevented from biasing the first working arm.

14 ) The device of claim 1 , wherein the device includes one or more deactivation features that are located in the shuttle.

15 ) The device of claim 14 , wherein the shuttle covers at least one of the one or more deactivation features when the shuttle is in the first position, and at least one of the one or more deactivation features are exposed by the shuttle when the shuttle is in the second position.

16 ) The device of claim 1 , wherein the device includes a second working arm, and the shuttle is a first shuttle portion that is located on a first working arm side of the body and a second shuttle portion that is located on a second working arm side of the body.

17 ) The device of claim 16 , wherein the bias device is located on the first shuttle portion, the second shuttle portion, the body, the first working arm, the second working arm, or a combination thereof.

18 ) The device of claim 16 , wherein the first working arm, the second working arm, the central body, the first shuttle portion, the second shuttle portion, or a combination thereof include one or more deactivation features.

19 ) The device of claim 18 , wherein the first shuttle portion covers the one or more deactivation features in the body, misaligns the one or more deactivation features in the first shuttle portion with the bias device, or misaligns the one or more deactivation features in the first working arm with the bias device when the first shuttle portion is in the first position; the second shuttle portion covers the one or more deactivation features in the body, misaligns the one or more deactivation features in the second shuttle portion with the bias device, or misaligns the one or more deactivation features in the second working arm with the bias device when the second shuttle portion is in the first position; or both.

20 ) The device of claim 19 , wherein the bias device extends into the one or more deactivation features when the first shuttle portion, the second shuttle portion, or both are located in the second position.

21 ) The device of claim 16 , wherein the bias device is free of extension between the first working arm and the body, free of extension between the second working arm and the body, or both by a gap being created by the first shuttle portion, the second shuttle portion, or both being moved into the second position.

22 ) The device of claim 1 , wherein the body includes a third shuttle portion and the third shuttle portion extends a blade.
