Sharp well made scissors help immensely. Shop around for surgical scissors looking for heavier material. The hinge is also important, some get out of alignment when challenged with a tough cutting job but still work fine on softer tissue. Also avoid exposing the scissors to temperature extremes especially cold as that may weaken hinge components.I have never dubbed a rooster, but I can tell by the size and girth of a typical single comb that it is difficult. The single comb seems so sturdy almost like cartalidge. Whereas the pea comb seems more like the waddle; thin and floppy.
