Abstract
A metal sleeve including a metal body which surrounds an inner channel running between a proximal and a distal opening. The inner channel has at least one groove set back into the metal body, running in the longitudinal direction of the inner channel and stepped on both sides by a distal and a proximal front edge. The proximal front edge of the groove is produced by impact extrusion.

A metal sleeve comprising:
- a metal body which surrounds an inner channel running between a proximal and a distal opening,
- wherein the inner channel comprises at least one groove set back into the metal body, running in a longitudinal direction of the inner channel and stepped on both sides by a distal and a proximal front edge,
- wherein the proximal front edge of the groove is produced by impact extrusion, such that the metal body at least in an area of the proximal front edge has a fibre orientation which is characteristic for impact extrusion,
- wherein an outer contour of the metal sleeve in the area of the proximal front edge has a cross sectional tapering, and
- wherein the proximal front edge of the groove continuously curves from a maximum width in an area of the groove to a width of less than 25% of the maximum width of the area of the groove.
