A passive inhaler for delivery of a powder-form inhalation formulation from a blister strip with a plurality of blister pockets is proposed. The inhaler comprises a metallic piercing member (7) with two piercing elements (25,26) extending at least essentially in V-shape away from each other and being at least essentially flat. A contact member (30) is arranged between the piercing elements to contact a lid of a blister pocket in an area between separate openings formed by the piercing elements in the lid.
