Curved Cutting Edge Description:
The best curved edge choice is often the impact tolerate through hardened edge. Curved edges penetrate the roadway better than flat edges while carrying existing material forward to leave a smooth even surface.

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.
