A serrated blade features a cutting edge with a series of small, jagged teeth, resembling a saw. This design allows the blade to grip and slice through tough materials more effectively than a straight edge. Serrated blades are commonly found in kitchen knives, such as bread knives, and are also used in various outdoor tools. The unique shape of a serrated blade makes it ideal for cutting through items with a hard exterior and soft interior, like crusty bread or ripe tomatoes. Additionally, serrated blades are often used in hiking and camping gear, providing versatility for outdoor enthusiasts.
