There’s more to using a Wood Chisel than you may think.

Evolution of Chisel Design Until only a few decades ago, the top of the chisel blade was extended as a tang which was imbedded in the wooden handle (Fig.2).

Carving Chisels are similar in weight and design to Paring Chisels but come in a wide range of sizes with an even wider range of cutting edge shapes. [Extracted from the article]
