We have discovered a Skater's Device which comprises a telescoping tubular member extensible over a range of positions from a first innermost position to a second outermost position, thereon. Scribing means are fixedly positioned at one end of said telescoping tubular member and releasable locking means are connected to said telescoping tubular member to retain said telescoping tubular member at the desired position. The center pin means are fixedly positioned at the other end of said telescoping tubular member to fix and retain the center point. A toe loop scribing means is longitudinally and adjustably mounted to said telescoping tubular member to scribe a toe-loop circle tangent to the circle scribed by said scribing means.
