What is a characteristic of a skin saw?

• A. It has a straight blade
• B. It uses a rotary disk blade that is adjustable
• C. It is designed for straight cuts only
• D. It is used primarily for wood working

Answer: (B)

A skin saw is specifically designed for cutting through the skin of aircraft structures, which typically involves working with metal or composite materials rather than wood. The characteristic of using a rotary disk blade that is adjustable enables the user to make precise cuts in various thicknesses of material. This feature is essential in aviation work, as it allows for adaptability to different structural requirements and ensures that cuts can be made efficiently without damaging surrounding areas.

Moreover, the adjustable nature of the rotary disk blade helps in maintaining control over the depth and angle of the cut, which is crucial for achieving the desired structural integrity and finish in aeronautical applications. The other choices describe features that either do not apply to the skin saw or represent tools designed for different functions, highlighting why option B stands out as the correct choice.
