Crafters are tactical operators, concrete in speech and utilitarian in action. In social situations, they are directive and reserved. Crafters are masters at using tools of every type—artistic, technological, martial. Although they are introverts, they are authoritarian in their interactions with others and can be forceful at influencing people. They focus on accomplishing tasks efficiently and skillfully. To master the tool of their interest, ISTPs require a certain degree of seclusion in which to practice. The result is often a virtuosity that other types find difficult to match.
