Final answer:
Surgical scalpels are instruments with sharp edges that are used to incise skin and tissue. They are important tools in medical procedures to make precise incisions and minimize tissue damage.
Step-by-step explanation:
The instruments that have sharp edges and are used to incise skin and tissue are called surgical scalpels. Scalpels are commonly used in medical procedures to make precise incisions.
A surgical scalpel consists of a handle and a detachable blade. The blade has a sharp, thin edge that allows for clean and accurate cutting of tissue. It is important for the blade to be sharp to minimize tissue damage and ensure a smooth incision.
Some examples of surgical scalpels include the #10 blade, which is commonly used for general incisions, and the #15 blade, which is used for more delicate procedures.
