The use of damaged or too sharp currycombs for grooming entails scratches. If deeper parts of the skin are affected it leads to sustainable changes of the skin. If the scratch is cured well a narrow, band-shaped scar is left. A similar effect on the skin or leather surface have lacerations from hedge thorns or barbed wire whereby hedges normally cause less deep wounds due to the flexibility of their branches. As cattle for sure try to avoid paining thorn hedges in their daily pastures it can happen that they get into a tangle with the sharp parts of the plants when for example fleeing in panic from a swarm of warble flies.
