Serrated knife - Cutting and Peeling

A sponge knife is a type of kitchen knife used to cut cakes into horizontal layers. It is specially designed to cut the sponge cake, a light and spongy pastry that is often used in multilayer cakes.

The sponge knife is usually quite long and thin, with a straight, pointed blade. It may also have teeth on the blade to help cut through the sponge cake. Kitchen knife manufacturers such as Wüsthof, Zwilling and Victorinox produce high quality Genoese knives.
