Question 1: Describe the purpose of a craft knife in a workshop. What safety precautions should be taken when using it?

Answer: A craft knife is used for precise cutting of paper, card, or other thin materials. Safety precautions include cutting away from the body, using a sharp blade to avoid applying excessive force, and storing the knife safely when not in use.

Question 2: List three manual tools used for marking measurements on materials. Briefly explain how each is used.

Answer: 1. Pencil: Used for drawing lines and markings; easily erasable. 2. Ruler: Used to draw straight lines and measure lengths. 3. Marking gauge: Used to scribe parallel lines at a set distance from an edge.

Question 3: Sketch a simple design of a hand-held screwdriver. Label the handle, shaft, and tip.

Answer: A correct sketch would show a handle shaped for grip, a straight shaft extending from the handle, and a tip suitable for screwing or unscrewing screws. Labels should clearly identify each part.

Question 4: Explain the difference between a flat-head and a Phillips-head screwdriver.

Answer: A flat-head screwdriver has a flat, straight blade designed to fit into flat-head screws. A Phillips-head screwdriver has a cross-shaped tip designed to fit into Phillips screws, allowing for better grip and torque.

Question 5: Draw a design for a simple hand saw, highlighting the blade, handle, and teeth.

Answer: A clear sketch should show a long, narrow blade with teeth along one edge, a handle at the top or side for grip, and labels indicating the blade, teeth, and handle.

Question 6: Name two types of hammers used in woodworking and describe their uses.

Answer: 1. Claw hammer: Used for driving nails into wood and removing nails. 2. Mallet: Used for tapping or joining materials without damaging them.

Question 7: What is the purpose of a coping saw, and what type of cuts is it best suited for?

Answer: A coping saw is used for making intricate or curved cuts in wood or plastic. It is best suited for detailed cutting work and shaping edges.

Question 8: Sketch a layout for an ergonomic handle for a craft knife. Include the shape and any features that improve comfort.

Answer: A good sketch would show a handle with a contoured, rounded shape that fits comfortably in the hand, possibly with textured grips or finger indentations for better control. Labels should identify the ergonomic features.

Question 9: Identify two manual tools that are essential for marking and measuring in a design project. Explain why they are important.

Answer: 1. Ruler: For drawing straight, precise lines and measuring lengths accurately. 2. Pencil: For marking and sketching initial designs that can be easily erased or adjusted.

Question 10: Describe how a file is used in manual finishing processes. What are the different types of files and their purposes?

Answer: A file is used to smooth or shape rough edges of materials like wood or metal. Different types include flat files for broad surfaces, half-round files for curved surfaces, and round files for holes or rounded edges.

Question 11: Draw a double-ended file and label its two different types of filing surfaces.

Answer: A correct sketch shows a long, narrow tool with different textured surfaces on each end, such as a flat surface on one end and a rounded surface on the other. Labels should identify each filing surface type.
