What is LIE 4, 5, etc., and why is it needed?

The "Lie" refers to the angle at which the shaft aligns with the blade when the hockey stick is on the ice. This angle is measured by determining the distance between the blade and the shaft's resting surface. Depending on the player's position and playing style, a different Lie angle may be required.

A lower Lie angle (e.g., 5) means that the blade is closer to the ground, enabling you to handle the puck more flatly and make quicker passes. A higher Lie angle (e.g., 7) means the blade is farther from the ground, allowing the player to handle the puck higher and facilitate shooting.

It's important to note that the appropriate Lie angle depends on several factors, including height, playing style, and position. The best approach is to try out different Lies, and over time, you'll find which angle suits you best.
