By observing front view of the Tool B, we can summarize that cutting tool used 0.8 milion year ago had wider diameter than Tool A which was used 1.4 million years ago. Additionally, end of the tool became sharper with progression of time and this trend can be clearly observed by looking at side view and front view of Tool A and Tool B.
