Human Factors
After my pre-flight inspection; I towed the aircraft out of the hangar; closed the hangar doors and locked them; then I boarded the aircraft; started up; taxied to the run-up area and did my run-up. At this point nothing altered me that anything was wrong. I then taxied to the runway; lined up; announced my departure; then went to full power/throttle when I heard a loud metallic sound and felt a bump. I immediately withdrew the power and announced my aborted takeoff. I taxied back to the ramp; out of the way; and shut down the aircraft. When I got out I realized I had never removed the tow bar from the nose wheel; then I observed the propeller and noticed that both tips had come into contact with the bar and were damaged. I retrieved the damaged tow bar from the runway and pushed the aircraft back to the hangar with the help of some other pilots on the field. Looking back; I simply should have done another walk around of the aircraft (after the pre-flight inspection) before getting into it.
C172 pilot reported an aborted takeoff because the tow bar was still attached.
