An articulated knife rotor assembly in a machine for reducing materials includes a shaft rotated about the longitudinal axis thereof. A plurality of blade holders are rigidly fixed to the shaft for rotation therewith. Each blade holder extends from the shaft generally radially with respect to the axis of the shaft. Each blade holder has mounted therein for relative rotation with respect thereto about an axis of rotation at least one block member. Each block member has fixed thereto at least one knife blade. Rotation of the shaft causes rotation of the blade holders, the block members and the knife blades. However, each knife blade is pivotable with respect to the respective blade holder about the axis of rotation of the respective block member.
