The jaw is movable from an open to a clamping position, wherein the blade-facing surface of the jaw liner opposes the blade with the first and second blade-facing surfaces of the structural body disposed on either side of the jaw liner and the blade. The blade defines a first longitudinal axis and a first radius, the first and second blade-facing surfaces of the structural body cooperate to define a second radius centered on a second longitudinal axis, and the blade-facing surface of the jaw liner defines a third radius centered on a third longitudinal axis. The first radius and the second radius of curvature are different from one another.
