ルッツジャンプ
The ISU defines the Lutz jump as "a toe-pick assisted jump with an entrance from a back outside edge and landing on the back outside edge of the opposite foot". It is the second-most difficult jump in figure skating and "probably the second-most famous jump after the Axel". It is named after figure skater Alois Lutz from Vienna, Austria, who first performed it in 1913. In competitions, the base value of a single Lutz is 0.60; the base value of a double Lutz is 2.10; the base value of a triple Lutz is 5.90; and the base value of a quadruple Lutz is 11.50. A "cheated" Lutz jump without an outside edge is called a "flutz".
