         thimble eye 110.
           Figure 12 is a front view of the thimble 102 of figure 11.
         Figure 13 is a rear view of the thimble of figure 11. Figure
         14 is an isometric,  cross-sectional, right side view of the
         thimble 102 along line 6-6 of figure 11. As shown in figures
         12-14, in some examples, a curved outer surface 156 may
         extend between the front face 136 and the rear face 138 of
         the thimble  102, which  together form the U-shape of the
         thimble eye 110. The outer surface 156 may be a convexly
         curved surface that extends towards the base 114. The outer
         surface 156 may have dimple features 158 formed therein
         that may be spaced along a length of the outer surface 156.
