On March 12, 2010, Stanley Works officially acquired Black & Decker. The end result was Stanley Black & Decker (SWK), currently the largest toolmaker in the United States. The merger paired the leader in consumer and industrial hand tools and security with a leader in power tools. Since then, Stanley has made a continued effort to diversify into higher growth and higher margin businesses, increase emerging market exposure, and shed assets they feel don't fit with that strategy.
