'die Spitze' and 'die Nase' can both mean the front or outermost part of something. 'die Spitze' usually describes a narrow, pointed end, for example on a pencil, knife, or arrow. In this relation, 'die Nase' means the very front part of a vehicle, especially an airplane or ship. Learners may confuse the words because both refer to a kind of front end. The important point is: 'Spitze' describes the shape more, while 'Nase' describes the position at the front of certain vehicles more.
