Mustad R39942NP-BN Demon Perfect Circle Hooks (Old Reference: R39942BLN) are Opti-angle needle point, chemically sharpened, nor-tempered, kirbed, point curved in, ringed, black nickel, 3X Strong. Designed for easy baiting, superior presentation and high performance. Working closely with fisheries experts, charter and long range captains, Mustad hook designers set out to create a new circle hook range that combines Mustad’s legendary strength with important new features to enhance performance. The new Demon Perfect Circle Hooks are the only circle hooks with Precision Proportions. This revolutionary design aspect means the point angle and length, gap, front length and all other parameters have the same proportions across the entire size range for maximum effectiveness. The range also boasts a new modified point design with a 96º angle which is optimum for insuring a high percentage of lip and jaw hooking.
