For which purpose is it essential to ensure gaffs are properly sized and shaped?

Ensuring that gaffs are properly sized and shaped is crucial for safety and performance during climbing and working at heights. Gaffs are sharp metal points that attach to a climber's boots, allowing for secure footing on poles or trees. If gaffs are not correctly sized or shaped, it can lead to instability, increasing the risk of slips or falls, which can result in serious injuries. Properly designed gaffs contribute to the ability to maintain grip and balance while working, which is essential for performing tasks efficiently and safely.
