The symbol represents the traditional tools of the miner, a hammer and a chisel on a handle, similar to a pickaxe, but with one blunt end.
They are pictured in the way a right-handed worker would lay them down: the pick with the point to the right and the handle to the lower left, the hammer with the handle to the lower right and the head to the upper left.
In coats of arms the symbol is often shown in black (Johanngeorgenstadt, Hövels), but also in natural colours (Telnice) or in gold or silver (Abertamy, Bodenwöhr, Gelsenkirchen).
The hammer and pick is used to indicate the working day, on timetables.
As an emoji, it is often used as a symbol by fans of Premier League side West Ham United, Ukrainian Premier League club Shakhtar Donetsk, and Eerste Divisie football club Roda JC Kerkrade.
