Sutcliffe-san - if she used hers - would've made her attacker fixate on something they'd lost. It would've lasted throughout yesterday.

So far I haven't heard of anything that can conjure fire... but the chainsaw had to have been in the circus at some point, because it was still warm when they found it in the opium den. Either because it was on, because Sutcliffe-san could use it even if it doesn't have fuel, or because it still had the heat from the fire.
