How about getting him a customized hammer with his name or initials engraved on it? You could also get him a set of woodworking chisels or a woodworking toolset. Another idea could be to organize a DIY workshop for him where he gets to learn some advanced carpentry techniques from a professional. If he enjoys reading, you could buy him a book on table saw techniques or furniture making that he could refer to while working on his projects.
Or you can get him a star map with the date of your first kiss.
