A web of toilet tissue that includes a shaped line of weakness, wherein the toilet tissue exhibits a LWP Factor of greater than about 7, and a Geometric Mean Peak Elongation of greater than about 15%, as measured according to the Dry Tensile Strength Test Method.

A drilling jig for drilling a punching hole with a boundary between a basis material and a coating of a workpiece less noticeable, and a drilling method using this drilling jig. It includes a male blade, a female blade, and a hexagon bolt; the male blade and the hexagon bolt are capable of being coupled to each other; a screw hole, through which the hexagon bolt is inserted, and a blade portion are formed in the male blade; the blade portion has a planar blade surface; a shaft insertion hole, through which the hexagon bolt is inserted, and a blade portion housing hole capable of housing the blade portion are formed in the female blade, whereby the boundary between the basis material and the coating of a bumper can be positioned on the inside of the punching hole, preventing the appearance of the punching hole from being impaired.

A ball-lock tool retainer insert includes a retainer insert body having a generally flat top and bottom face and a generally elongated non-circular cross-section. A lower portion and an upper portion of the retainer insert body each have a constant cross-section with the upper portion cross-section being larger than the lower portion cross-section thereby forming an enlarged shoulder. The retainer insert body has a tool aperture with a constant cross-section extending from the top face to the bottom face for receiving a tool and an angle hole adjacent the tool aperture extending from the top face and partially extending into the tool aperture for holding a ball lock. The retainer insert body is adapted to be received by a retainer block having a generally elongated non-circular hole with a counterbore such that the enlarged shoulder of the retainer insert body fits into the counterbore.
