Abstract: There is provided tee having a ground engaging arrowhead spike portion (150) formed integrally with a substantially planar head portion (151) via a transition zone (152). The transition zone (152) is bored through at (153) to enable connection by cord to articles. The substantially planar head portion (151) is hexagonal and has a single, hexagonally arranged, annular array of substantially parallel bristle tufts (154) surrounding a central ball support tuft (155) of stiffer bristles. The substantially planar head portion (151) has a peripheral impact-distributing groove (156) which may optionally receive an O-ring or the like.
