Which angle is recommended for honing a chisel to optimize chipping results?

• A. Honed edge at 70 degrees
• B. Honed edge at 45 degrees
• C. Honed edge at 30 degrees
• D. Honed edge at 90 degrees

Answer: (A)

Bevel angle on a chisel controls edge durability versus sharpness. A steeper bevel makes the edge thicker and stronger, which helps resist chipping under impact. For chisels that are struck and used on hard materials, honing toward a seventy-degree edge provides a robust, chip-resistant edge while still offering a usable cutting face. Sharper angles, like thirty or forty-five degrees, cut more easily but chip or dull quickly under hammer blows. A ninety-degree edge would be too blunt to cut effectively and would still be prone to damage. So honing at about seventy degrees best optimizes chipping resistance.
