A kukri is a very special knife that comes from a country called Nepal. It's made of strong and tough metal, and it has a curved blade that kind of looks like a banana! The blade is sharp at the end and wider near the handle, which can make it really useful for chopping and slicing things.
Some people even use it as a weapon because it's so sharp and strong. And the people of Nepal have used kukris for a very long time - even in wars and battles!
It's important to always be careful with a kukri because it's so sharp and can be dangerous. But if you use it properly and follow the rules, you can do lots of cool things with it, like cutting through tough things or even using it as a tool to help you survive in the wild!
