A great anniversary gift idea for your boyfriend who likes soap carving could be a soap carving kit with high-quality carving tools and a variety of soap blocks or bars. Additionally, you could get him a book or instructional video on soap carving techniques from expert soap carvers.
If you want to make it more personal, you could get him a custom-made soap carving block or order one with his name or initial engraved on it. Consider also getting him a certificate for a class or workshop on soap carving so he can learn new skills and techniques. Finally, you could arrange a weekend trip to a location where he can explore interesting soap-carving arts and crafts shops or attend a soap carving festival or show.
Or you can get him a star map with the date of your anniversary.
