When grinding a cold chisel specifically for the purpose of splitting nuts, the appropriate angle for the point angle is typically between 40 and 50 degrees. This angle strikes a balance between ensuring enough strength and durability in the chisel's edge while also providing adequate sharpness to facilitate effective splitting.

A point angle that is too acute may lead to rapid wear and potential damage of the chisel when used on hard materials like nuts. Conversely, a more obtuse angle could result in a tool that is less effective for the intended task, making it harder to penetrate and split the material. Therefore, the 40–50 degree range is optimal for achieving both durability and functionality in the task of splitting nuts.
