No, a SplicingNut is not someone who absolutely “loves” splicing above all else on his boat, nor is it some- one who’s been driven ’round the bend by splicing double braid. It is, instead, a two-part glass-reinforced-polymer device that has a certain nut-like appearance and can be used to form a loop in some lines. The line is wrapped around the black piece of the apparatus, as shown above and at left below. An eye, or loop, of any size can be formed in this way. Three sections of line and the black piece fit snuggly in the second piece, as shown at right below. The final construction, not shown here, brings the two pieces completely together.
