He’s a chip off the old block

This idiom is used to describe a person who closely resembles one of their parents, usually the father. It suggests that the person has inherited similar traits, characteristics, or talents from their parent. The phrase “a chip off the old block” implies that the person is like a small piece (chip) that has been cut or chipped from the same block as their parent, indicating a strong resemblance or similarity.
For example, if a son has the same sense of humor, work ethic, and mannerisms as his father, one could say, “He’s a chip off the old block.” This means that the son is very much like his father in many ways. This idiom is often used in a positive or affectionate manner to highlight the connection and similarities between generations. It can also imply a sense of continuity and tradition within a family.
