1. A screw, comprising:
- a shaft section which extends axially,a screw thread at the shaft section, which screw thread has thread turns that extend radially starting from the shaft section,a screw tip section which connects to the shaft section,at least one first scraping edge at the screw tip section,at least one second scraping edge in a region of the shaft section adjacent to the screw tip section,wherein the at least one first scraping edge and the at least one second scraping edge are at a distance from each other and extend in the axial direction over different sections of the screw;
wherein mutually facing ends of the at least one first scraping edge and the at least one second scraping edge are arranged within the same thread turn.

Abstract
A screw has a shaft section which extends axially, a screw thread at the shaft section, which screw thread has thread turns that extend radially starting from the shaft section, a screw tip section which connects to the shaft section, at least one first scraping edge at the screw tip section, and at least one second scraping edge in a region of the shaft section adjacent to the screw tip section. The at least one first scraping edge and the at least one second scraping edge are spaced at a distance from each other and extend in an axial direction over different areas of the screw.

18. A method for manufacturing a screw for introducing into an underground, the method, comprising:
-
forming a shaft section which extends axially, forming a screw thread at the shaft section, which screw thread has thread turns that extend radially starting from the shaft section, forming a screw tip section which connects to the shaft section, forming at least a first scraping edge at the screw tip section, forming at least a second scraping edge in a region of the shaft section adjacent to the screw tip section, and providing the at least one first scraping edge with respect to the at least one second scraping edge at a distance from each other, such that the at least one first scraping edge and the at least one second scraping edge extend in an axial direction over different sections of the screw and such that mutually facing ends of the at least one first scraping edge and the at least one second scraping edge are arranged within the same thread turn.

19. A method of use of a screw, comprising:
-
providing a screw having a shaft section which extends axially, the screw having a thread at the shaft section that extends radially starting from the shaft section, a screw tip section which connects to the shaft section, at least one first scraping edge at the screw tip section, at least one second scraping edge in a region of the shaft section adjacent to the screw tip section, wherein the at least one first scraping edge and the at least one second scraping edge are at a distance from each other and extend in the axial direction over different sections of the screw, and mutually facing ends of the at least one first scraping edge and the at least one second scraping edge are arranged within the same thread turn, introducing the screw in a manner without drilling a pilot hole, into a wood underground, and applying a driving force to the screw.
