Bread lame is a specialized tool used by bakers to score the surface of bread dough before baking. This scoring allows the bread to expand properly in the oven, creating a beautiful crust and preventing it from bursting in unwanted places. Typically, a bread lame consists of a handle and a thin, sharp blade that can be replaced when dull. It is an essential tool for artisan bakers who want to achieve professional-looking loaves with intricate designs.
