Reason: Perfect sharp trailing edge is difficult to build. ] Both and are true and is the correct reason for

Trailing edge is most rearward portion of an airfoil. Most airfoils are of blunt trailing edge. The perfect sharp edge as per given requirements and specifications is very complex and difficult to construct. Hence, airfoils uses blunt trailing edge with very small but finite thickness.
