The Vanfook SP-31F is a medium-wire barbless hook engineered in Japan for heavier spoons and stronger trout. Designed to balance power with precision, it pairs perfectly with 1.8 – 2.8 g spoons where a firm hook-set and reliable holding strength are key. The medium wire gives confident penetration without bending out, while the narrow gap keeps the spoon tracking true and natural. Available in: #6 is a 16-pack, and #8 is a 50-pack.
