What is a jam knife?

A jam knife is a tool that has been specifically designed for preparing jam. It has a long, thin blade that is typically made of stainless steel. The blade is straight, but it does not have a sharp point. This is because the knife is not used to cut or slice anything. Instead, it is used to spread the fruit, sugar, and other ingredients together in the jam-making process. The blade is also flexible and slightly serrated. This allows it to cut through the fruit without crushing it. The handle is typically made of wood and is comfortable to grip. The length and shape of the blade make it easy to reach into the corners and bottom of the pot or saucepan that the jam is being made in.
