Description:
A flat edge is best suited for developing (pioneering) a road or performing heavy maintenance (removing holes). A better penetrating option is a flat serrated edge. A flat edge has limited ability to carry material forward. A better option for carrying material is a curved edge.

Attributes:
Where impact and abrasion are low, the thinner edge provides the most economical service. Thicker edges provide added strength and wear material for abrasive or high impact applications.
