Forged vs Casting - What's the difference?
Metal can be formed into the shape of a scissor in two ways. It can be forged (hammered under high pressure in machines) or it can be cast (melted and poured into a mould).
It's much cheaper to make a scissor by casting than forging. The end product looks virtually the same to the naked eye, but cast scissors are more brittle than forged scissors. They are more likely to break when dropped, rust easily, tend to have a shorter life span and can be harder for scissorsmiths to repair.
Most cheap scissors are cast and most premium scissors are forged, so be wary of cheap scissors being passed off as forged. Remember that top quality scissors which are forged from the finest quality steels will always cost more.
