A great gift idea for your grandpa who enjoys self-defense training could be a set of self-defense tools, such as a small and sleek pepper spray, a personal alarm that he can easily carry with him, or a tactical pen that can break glass and be used for self-defense. Another idea is to get him a subscription to a self-defense training program so that he can continue to learn and develop his skills. Additionally, you could get him a book about self-defense techniques or a voucher for a self-defense class at a local fitness center or martial arts studio. Finally, a nice customized gym bag or a high-quality water bottle could be practical gifts that he will appreciate while training.
Or you can get him a star map with an important date you share.
