What is the typical material composition of some older knife handles?

• A. Plastic
• B. Wood
• C. Brass
• D. Aluminum

Answer: (C)

The typical material composition of some older knife handles is brass. Brass, an alloy consisting primarily of copper and zinc, has historically been favored for its durability, resistance to corrosion, and aesthetic appeal. In surgical instruments, including knives, brass handles were commonly used due to their strong structural integrity and comfortable grip. This material could withstand repeated sterilization processes, which is essential for surgical settings.

On the other hand, while wood has been used in some knife handles for centuries, it is less common in modern surgical instruments due to hygiene concerns and the potential for splintering or damage over time. Plastic and aluminum, though more prevalent in contemporary designs, became more popular as surgical materials advanced, focusing on lightweight and easily sterilized options. Thus, brass is correctly identified as a typical material used for older knife handles in surgical instruments.
