Papa loves the Round Head Jig. Never in his wildest imagination did he think the design could be improved. It has. We added a Mustad 60ø flat eye, wide gap, needle point, black nickel hook. The hook point will remain upright rather than rotating to the side. Attach anything on the ring and barb collar, and you've made it into the 21st century and quite possibly the winner's circle. 1/8 x 1" base hole pin (one per cavity included).
