    • An elongated blade including a longitudinally curved first cutting edge formed on one side of the blade and for providing cutting engagement with an ice surface; a longitudinally curved second cutting edge formed on an opposite side of the blade and for providing cutting engagement with the ice surface, the second cutting edge being substantially parallel to the first cutting edge; a longitudinally extending, substantially planar first face projecting transversely and upwardly from the first cutting edge and forming with the horizontal an angle of between 1.5.degree. and 2.degree.; a longitudinally extending, substantially planar second face projecting transversely and upwardly from the second cutting edge and forming with the horizontal an angle between 1.5.degree. and 2.degree., the second face intersecting the first face so as to form therewith an elongated trough; and mounting means for attachment of the blade to a boot. The blade provides for skaters an improved combination of both speed and control.
    • 细长刀片,包括形成在刀片的一侧上的纵向弯曲的第一切削刃,并用于提供与冰面的切削接合; 一个纵向弯曲的第二切割刃,形成在刀片的相对侧上,用于提供与冰表面的切割接合,第二切削刃基本上平行于第一切削刃; 纵向延伸的基本上平面的第一面从第一切割边缘横向和向上突出并且在水平方向上形成1.5°至2°的角度; 从第二切割边缘横向和向上突出的纵向延伸的基本上平坦的第二面,并且在水平面上形成1.5°至2°之间的角度,第二面与第一面相交以便形成细长的槽; 以及用于将叶片附接到靴子的安装装置。 刀片为溜冰者提供了速度和控制的改进组合。
