When cutting into fibrous glass duct board, which hand tool is MOST effective?
When cutting into fibrous glass duct board, the most effective hand tool is a straight knife. A straight knife provides clean and precise cuts, which are essential for working with fibrous materials. Tools like jigsaws, snips, and nibblers are not as effective for this specific task, as they are typically more suited for cutting through materials like metals or plastics rather than fibrous glass.
