matty- the cows have thinner horns are just not as masculine looking. sometimes they have horns longer than a bull but much thinner. bulls have a thicker neck etc.
rob- no they are a 2 piece laminated broadhead. the tuskers are a 3 piece.
here's one on an adapter unsharpened.
a sharpened one.
this is the side profile of a sharpened one. i just love how the ferrule taper goes right to the tip. STRONG!!
you american guys should check them out. they are a great head. they would be good value for you too as they are A$35.70/half dozen, cheaper if you bulk order. google blackstump broadheads for more info.
