Abstract
A spear head assembly includes a spear point having a proximal end and an opposite pointed end. A sleeve has an axial passage and a first end from which the spear point extends, the spear point coupled to the sleeve wherein the spear point can pivot relative to the sleeve and move axially relative to the sleeve. The first end of the sleeve has a smooth continuous abutment surface for the spear point, and the abutment surface forms a funnel like structure which reduces in inner diameter in a direction inward of the sleeve, with the funnel like structure extending between an outer circumferential surface and an inner circumferential surface of the sleeve.
