According to the records of Burkhard of Nellenburg, in 1090 Hemo gave Hemmental, together with Buesingen and Berslingen, to the Abbey of Allerheiligen in Schaffhausen.

In the year 1483, the name "Schlatter" first appears in Hemmental, followed by those of "Mettler", "Hatt" and "Leu".

Today, there are also the four place names, Schlatter, Leuen, Hatten and Mettlerhof reflecting this influence.

It is these four names which, in 1951, led to the resolution that a new village coat of arms be introduced - four golden stars on blue and red shield.

The blazon of the municipal coat of arms is Per saltire Gules and Azure in each a Mullet Or.
