    • An arrow rest including a magnetic ring mounted with respect to an archery bow. The magnetic ring includes an inner surface that defines an arrow shaft passage and an outer surface. The magnetic ring produces a first magnetic field about the arrow shaft passage. The magnetic ring forms an opening between the inner surface and the outer surface, and a shaft of an archery arrow is passable through the opening to position the arrow shaft within the arrow shaft passage. The archery arrow is movable between a loading position and a drawn position. In the drawn position, the first magnetic field interacts with a second magnetic field produced by a second magnet mounted at a tip portion of the archery arrow to suspend a portion of the arrow shaft within the arrow shaft passage.
    • 包括相对于射箭弓安装的磁环的箭头休息。 磁环包括限定箭头轴通道和外表面的内表面。 磁环围绕箭头轴通道产生第一磁场。 磁环在内表面和外表面之间形成开口,并且射箭箭头的轴可穿过开口,以将箭头轴定位在箭头轴通道内。 射箭箭头可在装载位置和绘制位置之间移动。 在绘制位置,第一磁场与由安装在射箭箭头的尖端部分的第二磁体产生的第二磁场相互作用,以将箭头轴的一部分悬挂在箭头轴通道内。

    • A method for forming a cutting edge along an edge portion of a blade stock, wherein the method includes moving the blade stock with respect to a first cutting element rotating about a first rotational axis, the first rotational axis forming one of an acute angle and a perpendicular angle with respect to the cutting edge, and contacting the edge portion and the first cutting element and forming a first cutting surface along the edge portion. The method may also include moving the blade stock with respect to a second cutting element rotating about a second rotational axis, the second rotational axis forming one of an acute angle and a perpendicular angle with respect to the cutting edge, and contacting the edge portion and the second cutting element and forming a second cutting surface along the edge portion so that the second cutting surface intersects the first cutting surface to form the cutting edge. In one embodiment of this invention, at least one of the first rotational axis and the second rotational axis is oriented in a skewed position with respect to a line of the edge portion or a line tangent to an arc segment of the edge portion.
    • 一种用于沿刀片坯料的边缘部分形成切割边缘的方法,其中所述方法包括相对于围绕第一旋转轴线旋转的第一切割元件移动所述刀片坯料,所述第一旋转轴线形成锐角和 相对于切割刃垂直的角度,并且接触边缘部分和第一切割元件并且沿着边缘部分形成第一切割表面。 该方法还可以包括相对于围绕第二旋转轴线旋转的第二切割元件移动刀片原件,第二旋转轴线相对于切割刃形成锐角和垂直角之一,并且使边缘部分和 所述第二切割元件沿着所述边缘部分形成第二切割表面,使得所述第二切割表面与所述第一切割表面相交以形成所述切割边缘。 在本发明的一个实施例中,第一旋转轴线和第二旋转轴线中的至少一个相对于边缘部分的线或与边缘部分的弧段相切的直线定位成倾斜位置。
