Hand-operated implement with controllable hand grip rotation

A hand-operated implement with controllable hand grip rotation, comprising:

• a first tool member pivotally connected to a second tool member via a pivot,
• wherein the first tool member includes a first tool head at an upper end and a first handle at a lower end on an opposite side of the pivot,
• wherein the second tool member includes a second tool head at an upper end and a second handle at a lower end on an opposite side of the pivot,
• wherein the first handle includes a first shaft having a longitudinal length between a first upper end and a second lower end of the first shaft, a first handle cover, and a first tension system,
• wherein the first handle cover has a longitudinal length and is disposed over at least a portion of the first shaft, and
• wherein the first tension system operatively connects the first handle cover to the first shaft, with the tension system being adjustable to place at least three different amounts of force between the first shaft and the first handle cover such that the first handle cover can be either fixed against rotation or rotatable in relation to the first shaft upon application of a minimum amount of rotational force to the outer surface of the first handle cover.
