Ulu is a special kind of knife that comes from the Inuit people who live in the very cold parts of the world, like Alaska and Canada. The word "ulu" means "women's knife" in the Inuit language, because it was mostly used by women to do all kinds of cutting jobs.
The ulu has a rounded blade that is usually made of a special kind of metal, and it is attached to a handle made of wood, bone, or other materials. This special blade allows people to cut things easily without having to use a lot of force. It can be used to cut meat, fish, and even vegetables.
The Inuit people have been using the ulu for a very long time, and it is a very important part of their culture. Some families even have special ulu knives that have been passed down from generation to generation. Nowadays, many people from all over the world use the ulu knife in their kitchens, because it is a versatile tool that can be used for many different tasks.
