How is a 1/64" undersized grip created?

A 1/64" undersized grip is created by either stretching it beyond its original size or by using a larger grip core size relative to the shaft butt size. When a grip is stretched, it is effectively elongated by about ¾", which decreases its overall diameter, making it feel smaller in the player's hands. This option is valid as stretching the grip can lead to a slight size reduction by altering the grip's original dimensions.

Additionally, choosing a grip with a larger core size allows more room for the grip to fit over the shaft while matching the smaller end measurement required for an undersized fit. This approach modifies the effective diameter of the grip, which can be beneficial for players who prefer a smaller grip for control, comfort, or feel.

In contrast, other choices do not achieve the effect of undersizing a grip as precisely. Adjusting shaft length, for example, primarily impacts the lie and length of the club, not the grip size. Using a smaller grip core size would typically result in a tighter fit but not necessarily undersize it effectively. Applying fewer layers of grip tape would indeed reduce thickness, but it doesn't specifically correlate to the 1/64" undersized measurement in a controlled manner. Thus, the most accurate way to
