What should the gaff tip contour function as when properly sharpened?

The gaff tip contour, when properly sharpened, should function as a chisel. This shape is crucial because it allows the gaff to penetrate the surface of the pole or structure the lineman is climbing. The chisel-like edge creates a clean cut into the material, providing a secure grip and stability as the climber ascends or descends. Such contours ensure that the gaff can be inserted with minimal resistance and maximal effectiveness, promoting safety and efficiency in climbing operations.

While other shapes like a fulcrum or needle point might imply different functionalities, they do not align with the specific needs of a gaff tip in climbing applications. A spike, while it suggests a pointed shape, does not adequately describe the necessary design for secure placement and grip as effectively as a chisel-like contour does.
