One great idea for a Christmas gift for your grandpa who enjoys leatherworking could be a high-quality leathercraft kit. This kit could include everything he needs to create his own leather items, such as leatherworking tools, dye, thread, and project ideas. Another idea could be a book on the history and techniques of leatherworking or a subscription to a leatherworking magazine. You could also consider gifting him a personalized leather portfolio or journal with his name engraved on it, or a leather apron for him to wear while working on his projects.
Or you can get him a star map with an important date you share.
