The Smitty’s Belts Complete Hollow Spectra Splicing Needle & Latch Hook Set contains all the needles you could possibly need to splice monofilament into hollow core braided lines or create loops for wind-on leaders. This kit contains a wide array of needle sizes that are capable of splicing monofilament ranging from 30lb test to 200lb test, two differently sized loop needles, and three differently sized latch hook needles. All Smitty’s Needles are hand-made from medical grade 304 stainless steel tubing. The tubing used has a thicker wall than the tubing used by other needle manufacturers and has proven to be the best and most durable on the market. The tube is welded closed and ground to a slightly rounded tapered point. The entire needle is then highly polished, thoroughly cleaned inside and out to guarantee it’s free of burrs and debris, and then inspected by hand to ensure quality standards are met.
