A shears (10) for cutting sheet metal or similar material located in a raised position, such as above the shoulders of the operator, includes front (18) and rear (20) handle members and upper (12) and lower (14) blade members. The handle members (18,20) are pivotally connected together at a handle pivot point adjacent the upper ends of the handle members. The blade members are pivotally connected together at a blade pivot point (16) located above the pivoted upper ends of the handle members (18,20). In addition, the shanks of the upper and lower blade members (12,14) are pivotally connected to the front and rear handle members (18,20) at respective front (32) and rear (34) pivot points located along the lengths of the handle members (18,20). Each blade member (12,14) includes a cutting edge (64,66) that extends perpendicularly or obliquely relative to the longitudinal direction of the handle member (18,20) to which the blade member (12,14) is pivotally connected. The handle members (18,20) may be provided with soft cushion-like hand-grips (24,26) to improve the operator's comfort and grip.
