A sheet finishing apparatus includes a media path configured to receive a sheet of media moving along the media path. A creasing tool is located proximate to the media path and is configured to form a crease in the sheet of media. The apparatus also includes a sheet folding device configured to fold the sheet of media along the crease. The creasing tool is preferably configured to operably move from a first position wherein the creasing tool is retracted away from the media path, to a second position wherein the creasing tool can contact a sheet of media moving along the media path and thereby form a crease in the sheet.
