How about a personalized archery set? You can get a unique bow and arrows custom made just for him, with his name engraved on the equipment. Alternatively, if he already has a bow, you could consider upgrading his arrows to premium ones made from high-quality carbon fiber. If he's interested in learning more about archery, you could get him a book on the history of the sport or a membership to a nearby archery range where he can practice and take classes.
Or you can get him a star map with the date when he was born.
