Abstract

An ear tag for marking an animal includes a first tag part and a second tag part having an accommodation opening. A pin has a conically pointed head at one end for passing through the accommodation opening, and the pin connects to the first tag part at its other end. A shank extends between the head and the first tag part. The head includes a cutting body having cutting edges extending generally away from the conical point toward the shank. The cutting body is embedded in the head with the cutting edges defining an outer surface of the head. The cutting body is harder than an embedding material of the head. Forces required to attach the ear tag are reduced by cutting action of the cutting edges.
