A blade assembly for applying the flowable material includes a blade disposed behind the back wall. At least one connection member connects the blade to the body such that the blade is moveable to selectively engage the bottom application edge with the flowable material. A connection between the connection member(s) and the blade or the body is configurable in first and second alternate configurations. In the first configuration, the connection member(s) maintain the bottom application edge at a constant orientation with respect to the body. In the second configuration, the connection member(s) allow a variation of the orientation of the bottom application edge with respect to the body.
