[Yoda]

The Dowel has a Sweetspot (located at its tip). The Golf Club has a Sweetspot (located on the Clubface). Both should be pointed at the Straight Plane Line.

And except during Start Up and Release, the Dowel/Clubshaft is the On Plane Visual Equivalent of the Clubface Sweetspot's invisible Centrifugal Line of Pull.

Shanking is (1) a total loss of Clubhead Lag Pressure Feel and (2) the ability to deliver that 'Feel' Down Plane into the inside-aft quadrant of the Ball. But the Good News is ...

The same Pressure Point Pressure that will deliver a Dowel's Sweetspot into Impact On Plane will deliver a Clubhead's Sweetspot into Impact On Plane.

The solution, as always, is Educated Hands.

And a Pivot that has been trained to obey.
