1 Flat chisel: Flat chisels have a straight, flat cutting edge and are commonly used for general cutting, shaping,
and carving tasks in woodworking, metalworking, and masonry. They come in various sizes and are versatile
tools for removing material, creating straight lines, or smoothing surfaces. Flat chisels are essential in tasks
such as cutting mortises, shaping wood, or chipping away excess material from metal or stone. They’re
typically struck with a mallet or hammer to apply force for cutting through the material.
2 Cross-cut chisel: A crosscut chisel, also known as a “mortise chisel,” is a type of chisel specifically designed
for cutting mortises, which are rectangular slots or holes typically used in woodworking joints.
