OK I figured out this "cattle leather", "pig skin", "water buffalo" thing and tips made from their leather.
The larger and heavier animals are "pre-compressing" the leather!
You have an animal, which weighs several tons, then the animal lays on its side just once... and presto! You have "pre-compressed" tip leather.
The Blue Whale is the largest mammal weighing over 190 tons... So it would be highly desirable to find a beached whale of this type lying on its side. Should make an excellent breaking tip! I don't know if the skin would be better before or after the whale was "blown up" with explosives (See Exploding Whale link below).
A Rhinoceros has the thickest skin, 1 inch thick that is. So tips made from this skin should last for a long time.
