How about a personalized whittling kit or a whittling book with his name engraved on it? You can also consider getting him a nice set of whittling tools or a bundle of unique wood pieces for him to work on. You may also want to look into classes or workshops on whittling in your area, and perhaps get him a pass to attend or enroll him in a few classes as a surprise gift.
Or you can get him a star map with an important date you share.
