Kernrechtsfrage
Whether the use of a kitchen knife qualifies robbery as aggravated robbery with a dangerous weapon under Art. 140 Ziff. 2 StGB.
Extrahierter Entscheid
A kitchen knife is an everyday tool, not a weapon within the meaning of Art. 140 Ziff. 2 StGB; using it for threats does not transform it into a weapon.
Extrahierte Begründung
The weapon concept depends on objective purpose, not on the concrete use in the case. A kitchen knife is not designed for attack or defense, and a broad reading would unlawfully expand the statutory notion of weapon.
