Apple Pencil Repairability 1 out of 10 (10 is easiest to repair):

The pen nib and cap can be replaced if worn out (or lost).

The pencil is clearly not meant to be opened or repaired; you can't get inside without destroying the device.

The layers of plastic and metal holding interior components are impossible to remove without shredding.

The battery, enough for a 12 hour run, is impossible to replace, giving the device a limited lifespan.
