A hammer and pick, as used for breaking up rocks in mining, crossed in an X shape. Generally depicted as metal, mallet- and chisel-styled hammers with wooden handles. The heads of the tools face up, with the pick usually at the right. Often used for various content concerning tools, building, and construction.
Facebook implements the same designs as for its 🔨 Hammer and ⛏️ Pick. Samsung’s design previously featured stylized, white tools on a green square, as a sign or icon of a mine.
Hammer and Pick was approved as part of Unicode 4.1 in 2005 and added to Emoji 1.0 in 2015.
