So annoying we can't add pictures.
I have a 30-40 year old toilet handle that is all metal. The part securing the handle from the inside of the tank is metal with 2 'prong' like pieces screwed onto the front piece. I have tried all the tools in my box to get it off and it is really on there. Any suggestions to unscrew it? I know most more current handles are reverse threaded, so that's the way I'm twisting, but now wondering if the really old ones maybe weren't reverse?
