How about getting your friend a professional knifemaking kit that includes all the necessary tools and materials to make a custom knife? Alternatively, you can consider purchasing a high-quality steel blade or a specialized sharpening stone for your friend's collection. If your friend enjoys learning about the history of knifemaking, you can also consider gifting a book about the history and techniques of the craft. Another idea is to enroll your friend in a knifemaking workshop or class with a professional instructor to teach new skills and techniques.
Or you can get her/him a star map with an important date you share.
