Steel Release: Monomolecular Wire

Using this technique, one can create monomolecular threads either from their own body, or from other Steel Release constructs. The threads are capable of slicing through any matter effortlessly, as they simply cleave apart the molecular bonds of whatever they slice. Since they are just a single strand of strongly bonded molecules they are invisible to the naked eye, including Doujutsu, even the famed Sharingan has only been shown seeing down to the cellular level, and this is smaller still. However this does not mean the threads are completely undetectable. There is still chakra in them and they can be detected by chakra sensory techniques, whether traditional or tactile in nature. Basically any non-visual form of detection can detect their presence as long as there is a half-way decent explanation as to why.
