To achieve the best performance from climbers, the gaffs must be properly what?

To achieve optimal performance from climbers, it is crucial that the gaffs, which are the sharp metal spikes attached to the climbers' poles, are properly sized and shaped. Proper sizing ensures that the gaffs will fit securely into the climbing surface, providing the necessary grip and support. If they are too large or too small, they may not penetrate the climbing surface effectively, leading to potential safety hazards.

Shaping the gaffs plays a vital role in their efficiency. Well-shaped gaffs will allow for a more natural angle of penetration into the climbing surface, making it easier for the climber to ascend while minimizing fatigue and the risk of slipping. Properly sized and shaped gaffs can also extend their lifespan and maintain their effectiveness over time.

While filing and sharpening gaffs is important for maintaining a sharp edge, it is the correct sizing and shaping that fundamentally ensures they perform effectively in the climbing environment. Thus, focusing on sizing and shaping is essential for safety and performance in climbing applications.
