The coupling mechanism (22) has a guide track guiding the implement (13) in the uncoupling position at an angle with respect to a longitudinal axis (68) of the housing (2) during its uncoupling movement along the compartment region. The housing has oppositely lying side walls, which respectively have convex gripping cams (59) on their top face projecting out beyond the external contour of the implement (13, 14, 5) when moved into the transport position and disposed symmetrically about the longitudinal axis (68) of the housing (2), the geometry of which is dimensioned so that in the uncoupling position, a part-length of the implement (13) lies within the compartment region and is covered by the side walls. ## Claims ### Claim 1 A pocket tool, comprising: a housing with at least one compartment region, a first pin and a second pin disposed in the housing, a spring element with a guide link connected to the housing, a saw blade interchangeably mounted to the first pin, and a glass-shattering tool interchangeably coupled to the second pin by a coupling mechanism;
