A device operated by hand power to create creases and folds in sheets of paper is a fundamental tool for various applications. These devices range from simple bone folders used for scoring and sharp creases to tabletop devices capable of more complex folds like letter folds, cross folds, and even specific folds for brochures or pamphlets. One common example is a lever-operated device used to fold paper for mailings or leaflet distribution.
The accessibility and affordability of hand-powered paper folding offers significant advantages, particularly for smaller businesses or individuals. These devices eliminate the need for tedious hand folding, increasing efficiency and ensuring consistent, professional-looking results. Historically, before the advent of automated folding machinery, these tools were essential in printing and binding, playing a vital role in the dissemination of information and literature.
