Historically being a handyman was considered a less prestigious occupation than a specialist such as a plumber, electrician, or carpenter. With the emergence of large national chains, there have been efforts to change that perception by emphasizing the professionalism of the trade and that a handyman is a technician with multiple skills and a wide range of knowledge. Handyman tools sometimes become useful in different places: for example, when a proper cranial drill was not available, an Australian doctor used a handyman's drill in 2009 to open a hole in the head of a 13-year-old boy to relieve pressure after a brain injury; the boy's life was saved.
