What is the correct statement about the No. 20 Blade?

The statement regarding the No. 20 Blade being designed for heavy tissue and bone incisions is accurate because this blade has a broad and robust design that makes it suitable for cutting through tougher tissues. The shape and size of the No. 20 Blade allow it to handle the demands of surgically cutting through thicker and denser structures, providing the necessary leverage and strength that is needed for such tasks.

Other options fail to correctly define the No. 20 Blade. The claim that it is used only on delicate tissues is misleading, as this blade is not intended for fine, delicate surgical work. Similarly, while some blades are specifically designed for removing sutures, the No. 20 Blade does not fall into this category; it's more focused on incision creation rather than suture removal. Lastly, while the No. 20 Blade can fit certain handles, it is not primarily associated with the No. 3 handle, which is often more adaptable for finer cutting tasks with smaller blades. This broadening of its application range is why the assertion about its use for heavy tissue and bone is the most suitable description.
