Which item is described as a long, narrow, two-sided file with extra grit and a final shine surface?

• A. Buffer Block
• B. Emery Board
• C. Nail Rasp
• D. Two-Way Buffer

Answer: (D)

A long, narrow, two-sided file with extra grit and a final shine surface is a two-way buffer. This tool is built for both shaping and finishing the nail in one sequence: the grit side handles initial filing and smoothing, while the final shine surface delivers a glossy, polished look. The other tools don’t match this combination—buffer blocks are broader blocks with multiple surfaces, emery boards are shorter flexible boards, and nail rasps have rough teeth for heavier shaping. The two-way buffer uniquely provides both a shaping/grit step and a final shine step in one instrument.
