That's interesting! How about getting him a sword that he can display in his home or office and also use for practice? You could also get him a book on sword fighting techniques or even enroll him in a sword fighting class if there's a reputable one in your area. Another idea is to get him a custom-made sword with his name or initials engraved on it. If he's into history, you can also get him a historical or replica sword from a specific period or country that he's interested in.
Or you can get him a star map with the date when he was born.
