pyramidal, wedge, or pinch point. They transition to a tapered round cross section 12 to 18 inches from the point. The handle end may terminate in a ball or may be cut off squarely at 5/8 to 3/4 inch diameter. They are made of forged steel and may be from five to six feet long. Lining bars may also be called jack bars, jack handles, or crowbars in North

these typically have a narrow, unsharpened chisel point at one end and a point at the other end, with diameters up to about 1.5 in (4 cm). Some have plastic grips on the shaft and some have wider chisel ends, or "rakes", for specific jobs such as removing old
