US Patent 11213939 Chisel

The chisel includes a tip (2), a working section (6), and an impact surface (3), and a longitudinal axis (7) that extends through the tip (2), the working section (6), and the impact surface (3). The working section (6) includes multiple webs (14) that extend along the longitudinal axis (7) and that are distributed about the longitudinal axis (7) in the circumferential direction (15). For at least one of the webs (14), a dimension (27) in the circumferential direction (15) increases by at least one-third with increasing distance (26) from the longitudinal axis (7). The webs become significantly wider toward the outside and thinner toward the longitudinal axis.
