1. A wiper blade (10) with a wiper strip (14) made of elastic material and having a wiper strip head (20) and a wiper lip (26) which can be placed on a window (22) to be wiped, wherein the wiper lip (26) is designed as a wedged-shaped extension (24) of the wiper strip head (20) and has a point angle (42) of between 60 degrees and 150 degrees, said point angle leading into a contact surface (44) having a radius (46) of smaller than 100 micrometers. 2. The wiper blade (10) as claimed in claim 1, characterized in that the point angle (42) is between 75 degrees and 135 degrees. 3. The wiper blade (10) as claimed in claim 2, characterized in that the radius (46) is smaller than 75 micrometers. 4. The wiper blade (10) as claimed in claim 3, characterized in that the wiper strip material has a modulus of elasticity (Y) of smaller than 10 Newtons per square millimeter. 5. The wiper blade (10) as claimed in claim 1, characterized in that the radius (46) is smaller than 75 micrometers. 6. The wiper blade (10) as claimed in claim 1, characterized in that the wiper strip material has a modulus of elasticity (Y) of smaller than 10 Newtons per square millimeter. 7. The wiper blade (10) as claimed in claim 1, characterized in that the wiper lip (26) has first and second surfaces (38, 40) enclosing the point angle (42) between them, the one, first surface (38) being produced by extrusion, injection molding or pressing and the second surface (40) being cut. 8. The wiper blade (10) as claimed in claim 1, characterized in that the point angle (42) is 90 degrees. 9. The wiper blade (10) as claimed in claim 1, characterized in that the radius (46) is smaller than or equal to 50 micrometers. 10. The wiper blade (10) as claimed in claim 1, characterized in that the wiper strip material has a modulus of elasticity (Y) of smaller than or equal to 5 Newtons per square millimeter. 11. A method for the production of a wiper blade (10) as claimed in claim 1, characterized in that the wiper strip (14) is extruded, injection molded or pressed in a first step in which one side (38) of the point angle (42) is manufactured and, in a second step, an additional volume (58) is cut off in order to produce the second side (40) of the point angle (42). 12. A wiper blade (10) with a wiper strip (14) made of elastic material and having a wiper strip head (20) and a wiper lip (26) which can be placed on a window (22) to be wiped, characterized in that the wiper lip (26) is designed as a wedge-shaped extension (24) of the wiper strip head (20) and has a point angle (42) of between 60 degrees and 150 degrees, said point angle leading into a contact surface (44) having a radius (46) of smaller than 10 millimeters, and at least the wiper lip is coated with a layer (54), the thickness of which does not exceed 100 micrometers. 13. The wiper blade (10) as claimed in claim 12, characterized in that the radius (46) does not exceed 10 millimeters and the thickness of the layer (54) does not exceed 5 micrometers. 14. The wiper blade (10) as claimed in claim 13, characterized in that the wiper lip (26) has first and second surfaces (38, 40) enclosing the point angle (42) between them, the one, first surface (38) being produced by extrusion, injection molding or pressing and the second surface (40) being cut. 15. The wiper blade (10) as claimed in claim 12, characterized in that the wiper lip (26) has first and second surfaces (38, 40) enclosing the point angle (42) between them, the one, first surface (38) being produced by extrusion, injection molding or pressing and the second surface (40) being cut. 16. The wiper blade (10) as claimed in claim 12, characterized in that the radius (46) does not exceed 5 millimeters and the thickness of the layer (54) does not exceed 25 micrometers. 17. The wiper blade (10) as claimed in claim 12, characterized in that the radius (46) does not exceed 1 millimeter and the thickness of the layer (54) does not exceed 75 micrometers. 18. A method for the production of a wiper blade (10) as claimed in claim 12, characterized in that the wiper strip (14) is extruded, injection molded or pressed in a first step in which one side (38) of the point angle (42) is manufactured and, in a second step, an additional volume (58) is cut off in order to produce the second side (40) of the point angle (42).
