Theres a toxin pistol and sprayer. they work like corrosive stuff (can destroy body parts and leave green stuff on it) but corrosive power has not been created...
The anniverary patch's scope was a couple new customisation features, and a ton of new items. I didn't want to add a random power or two, as I'm probably doing a power patch later down the line.
This should be coming in the anniversary patch (not 100% promising since it's not done yet, but it's been planned since the detail tool was added.) EDIT: Not possible after all. Technical issues.
The Cut Tool already achieves pretty much exactly that.
