Claim:
A variable length golf club shaft comprising: a hollow lower shaft comprising a wall having a plurality of holes; a hollow upper shaft comprising an exterior surface and an interior surface, wherein the interior surface comprises at least one protrusion sized to fit within at least one of the plurality of holes, and wherein the upper shaft is sized to slidably receive the lower shaft; and an unlocking bar sized to fit within the upper shaft and the lower shaft, wherein sliding the upper shaft over the lower shaft causes the protrusion to engage with at least one of the plurality of holes, wherein engagement of the protrusion with one or more of the plurality of holes fixes the upper shaft to the lower shaft, and wherein inserting the unlocking bar into the upper shaft and the lower shaft when the upper shaft is fixed to the lower shaft disengages the protrusion from the one or more plurality of holes and permits the upper shaft to move along a length of the lower shaft.
