When should I use a folding tool (bar folder) versus hand seamers?

Folding Tool (Bar Folder): Use this to make uniform, long, straight folds along the raw edge of sheet metal (like a 1/2-inch hem or drive slip fold) before hanging. Hand Seamers (Vise-Grip/Tongs): Use these for localized bending, crimping, fixing crushed corners, or making short, custom folds when the metal is already hung or in tight spaces where a long folding bar won't fit.
