Unwrap the shielding a bit and nick it at the base with some electronics side cutters.

If you will wire this cable in a terminal block instead of a Keystone or crimping on a connector, you should just remove the minimum amount of shielding needed to properly punch down the connection.

Make sure to not damage the delicate insulation of the individual wires.

Rip off the shielding.

Repeat for all four twisted pairs.
