The present invention relates to a string cutter.

Many different kinds of strings are used around our lives. Such straps vary widely in their kind and use, from packaging to tie boxes together to tying individual items together. For example, it is used to bind newspapers or various waste papers generated in a home or office to be recycled, and to bind boxes containing objects to prevent the box from opening or to make a handle for carrying the box.

On the other hand, among the strings, for example, a string of hard material, such as a PP band, it is difficult to tie a knot by hand and can be easily released even if so tied, use a separate binding accessory. The hardware for wrapping and fixing a string is typical. The iron is a plastic sheet capable of plastic deformation, and is folded by a binding device in a state of being folded twice to fix the string.

By the way, the binding method using the above-mentioned binding parts is inconvenient, remarkably low recycling rate, and in particular, since a separate binding device is required, it is used in places where packaging demand is somewhat used and is rarely used in general homes or offices.
