The KM-4 is a barbless spade end pattern, made from 110 hi-carbon and featuring a beak in-turned point. It is an extra-strong pattern for baggin' sessions, formed from a gauge of wire that is not too thick but ensures reliability of catch. Like many of Middy's hooks, the KM-4 is Teflon impregnated and has a dull anti-glint finish. The range goes from size 10 right down to a size 20, to allow for finesse presentation but with the security of knowing that even this smallest size hook will hold.
