Why do you cut notches at the end of sticks on a kite?

Cutting notches at the end of sticks on a kite helps to secure the string or bracing materials in place, providing better stability and control during flight. These notches create anchor points that prevent the string from slipping, which is crucial for maintaining the kite's shape and orientation in the wind. Additionally, they can help reduce the overall weight of the structure, allowing for improved performance in the air.
