Crimp

In bouldering, a "crimp" is a type of handhold that is small and requires the climber to grip it with their fingers bent at the second joint, creating a crimping position. This position places the thumb over the top of the fingers to add pressure and stability. Crimps are often challenging due to their small size and the significant finger strength needed to hold onto them securely. Climbers may encounter crimps on various routes and must develop specific finger strength and technique to use them effectively.

Examples

In bouldering, a climber encounters a small, sharp edge that only fits the toes or the tips of the fingers. This is known as a crimp. When tackling a crimp, they use the pads of their fingers, often bending the first knuckle sharply. For example, on an overhanging route, they might come across a thin ledge, barely enough for fingertips. Another instance is when they face a vertical wall with tiny edges, requiring precise finger placement and strong grip strength.
