A sheepsfoot blade has a straight cutting edge and a dull spine that runs parallel with the cutting edge and then sharply curves down towards the point, typically creating a 60° to 90° blade tip.
This blade pattern was originally designed for carrying out cutting and slicing tasks, where an acute tip could lead to unwanted piercing or nicking. The dull spine allows you to safely grip the blade with your fingers ('Choking up") or extend a finger to increase your fine blade control during delicate work. Sheepsfoot blades can be single bevel / 'chisel ground' or double bevel and are available with fixed blades or folding blades.
