A tool used to determine the stiffness of a hockey stick shaft, typically expressed as a numerical rating, helps players select equipment optimized for their physique, playing style, and skill level. This number represents the amount of force required to bend the shaft one inch. For example, a stick with a flex of 85 requires 85 pounds of force to bend it one inch.
Proper stick selection significantly influences a player’s ability to generate power and control the puck. Utilizing such a tool allows for informed decisions, matching individual characteristics with stick properties. Historically, players relied on subjective feel and often struggled to find well-suited equipment. This advancement represents a more objective and scientific approach, contributing to improved performance and reducing the risk of injury from using improperly matched equipment.
