The invention features implementation of a flat triangular blade which has wo cutting edges and a sharp point. The blade is caused to move pointwise across a cylindrical can's diameter, with the plane of the blade perpendicular to the can's axis, so that the point pierces the can, the two cutting edges slice through the can in both directions around the can's circumference, and the point again, diametrically oppositely, pierces the can. The inventive removal of the residual contents and propellants from a spent aerosol can is optimally effective, because the invention divides the can into two separate parts, concomitantly subdividing the can's internal components.

[ What is claimed is:] [1.] Apparatus for severing an object, said object having an exterior wall which is configured for effecting containment, said apparatus comprising:means for holding said object in position;a substantially planar blade having two equal right angled straight sides and two equal acutely angled straight sides, said two equal acutely angled straight sides each being adjacent to one said equal right angled straight side, said two equal right angled straight sides describing two equivalent blade edge regions, said two equal acutely angled straight sides describing a blade tip region, said two equivalent blade edge regions and said blade tip region having associated therewith two equal right angled straight inner blade demarcations meeting at a vertex, said two equal right angled straight inner blade demaracations each being parallel to one said equal right angled straight side, said two equal acutely angled straight sides meeting at a tip extremity, said two equal right angled straight sides approaching an imaginary point situated intermediate said vertex and said tip extremity, said blade tip region extending approximately between said tip extremity and said vertex, said two equal right angled straight sides and said two equal acutely angled straight sides all being coplanar, said two equal right angled straight sides, said two equal acutely angled straight sides and said two equal right angled straight inner blade demarcations all sharing an imaginary angle bisector which intersects said tip extremity, said imaginary point and said vertex; andmeans operatively connected to said means for holding for carrying said blade transversely with respect to said object whereby said blade is initially distanced from said object with said tip directed toward said wall, said tip region successively punctures said wall at two locations, and said two equivalent blade edge regions slice said wall between said two locations.
