Why is clubhead material important when bending the lie angle of an iron?

The significance of clubhead material when bending the lie angle of an iron primarily relates to its ability to withstand deformation and change in structure. Different materials have varying degrees of flexibility and ductility, meaning that some can be bent without compromising their integrity, while others may not be conducive to bending at all.

For example, clubheads made from softer materials like certain types of stainless steel can be bent more easily without risk of cracking or breaking compared to those made from harder materials. Thus, understanding the material composition helps determine how much bending can be safely and effectively carried out without harming the club's performance or physical structure.

Weight distribution, swing speed, and grip pressure are relevant to the overall performance of the club and the player's interaction with it, but they do not directly impact the process or limitations involved in bending the lie angle. The capability to manipulate the lie angle accurately hinges on the properties of the clubhead material itself, making it a crucial consideration in club fitting.
