Very delicate. What a thorough size lineup from #14 size. From the shape of the bend curve to the sharpness of the point, it is possible to exquisitely fine-tune the ultra-small minnow for trout. Please be careful when attaching! "When attaching to a Heaton type eye, it is best to open the Heaton side and attach it. Forced insertion from the hook side will cause deformation and damage to the hook."
