Stretch 1, like most of the times lately--
Here to be seen with a similarly sized, very old, traditional Austrian / Bavarian knife, called the "Hirschfaenger" ("deer catcher" in English).
Those were originally hunting knives. As far as I know starting from about the 16th century professional local hunters would carry two knives, one for skinning, and this "Hischfaenger" meant for killing wounded animals
Later they became all-purpose knives, carried by farmers, lumberjacks and the more rural men generally.
The famous Austrian/Bavarian "Lederhosen" (the knee-long leathertrousers) even have a dedicated side pocket for carrying this type of knives.
Still you can sometimes see older guys in the mountains cutting their bacon and bread for lunch with such blades.
