THE OVERSHAFT FERRULE
The option to upgrade.
Designed by Rush Kane and machined entirely from titanium, the Overshaft Ferrule allows graphite shaft upgrades on compatible over-the-shaft-style putter necks, without the bulk of a conventional-looking adapter.
Its slim, low-profile design blends almost seamlessly with the shaft, creating a clean transition that looks intentional from every angle. Finished with the signature RK mark and adding approximately 8 grams, it is a small component with nothing overlooked.
Why Upgrade to a Graphite Shaft?
Premium graphite putter shafts offer more than a different look. Purpose-engineered models combine low-torque construction with carefully tuned flex profiles, giving golfers options for stability, response, and feel suited to their stroke. Low torque helps resist twisting, while different flex profiles accommodate different tempos and preferences.
