Page 25 - Barbara Merry - The Splicing Handbook

Not all splicing tools are used to manipulate rope during the working of a

splice. The thimble is such a tool; it is a teardrop-shaped metal support for an
Eye Splice, with a grooved outer edge for the rope.
Variations of the Eye Splice are found throughout this handbook, showing its
popularity and virtuosity despite differences in rope construction and materials.
Without a thimble, it is effective for light-duty use, such as on a topping lift or
dinghy painter. With a thimble, the Eye Splice is ready for heavy use, when wear
and chafe must be considered. A thimble should be used whenever the line will
be attached to chain, swivels, or shackles, such as on the anchor end of an anchor
rode.
