ABSTRACT:
A simplified unitary teat knife is formed of stainless steel rod with a knurled knob on one end and an eye on the other. The eye is flattened and enlarged relative to the rod of the knife and the edges of the eye are sharpened so as to provide cutting surfaces for removal of obstructions within the milk duct as the tool is rotated within the duct by manual manipulation of the knurled knob.
