Which combination of materials is commonly used for the construction of a cross-cut chisel’s body and edge?
Body of mild steel, edge of hardened steel
A cross-cut chisel must be tough enough not to shatter when struck, yet hard enough at the tip to cut metal.
It is therefore made with a body of mild (tough) steel and a cutting edge of hardened steel, the edge being hardened and tempered for durability.
Hence, the body is mild steel and the edge is hardened steel.
