摘要：
A spur comprises a U-shaped heel section and a neck. The heel section shows a basis, at which the neck is fitted to and which heel section shows two lateral legs starting from the basis. Also, the heel section is cut to size out of a sheet metal and is bent in a U-shape. The heel section is also embossed so that the legs have a profile deviating from a rectangular cross-section shape of the blank.
