Blade: The knife typically has a single-edged blade with a sharp cutting edge. The length of the blade may vary depending on the specific model, but it is typically between 3 to 5 inches. The blade may have a tanto, drop point, or other common blade shape.
Handle Design: The handle of the butterfly knife is designed with two halves that pivot on a central pin. These handles can be swung open and closed, creating the distinctive flipping action associated with butterfly knives. The handles often have textured or contoured grips for improved handling and control.
