A format that allows to take it everywhere (even hiking the weight is bearable) and making it more versatile, especially for cutting pieces of wood. By cons, steel is a little too "soft", so that you will very quickly serrations on the cutting edge, but sharpening is easy and it will be easy to make up. It is a tool to consider if you choose not to take that, otherwise, a small knife and a folding saw will be safer and lighter. To conclude, given the price, do not hesitate to try it.
