The movable blade on shears is controlled by which grip?

• A. Thumb grip
• B. Palm grip
• C. Finger grip
• D. Wrist grip

Answer: (A)

The movable blade is controlled by the thumb grip because the design of haircutting scissors uses the thumb to operate the moving blade. When you place the thumb in the smaller inner ring and curl or extend it, you drive the action of the upper (movable) blade against the stationary blade. The rest of your fingers support and stabilize the tool, giving you precise control. Other grips change how the tool is held or moved—palm grip relies on the whole hand, finger grip focuses on finger placement rather than blade movement, and wrist grip relies on the wrist’s motion—so they don’t provide the same isolated control of the movable blade.
