A steel square, by no means, is intended or appropriate for verifying the evenness of a countertop. Its main function lies in measuring angles and ensuring perpendicularity, rather than determining the flatness of a surface. For the purpose of examining the evenness of a countertop, it is advisable to utilize a straightedge or a level, as these instruments are explicitly designed for this task.
