arm bar

In his overzealousness to land the killing blow, he’d stabbed through the rungs of the ladder to get at my heart. Before he could retract his arm I let go of the steel bars and grabbed the thick steel plate of what must have been his forearm and yanked sideways. Metal clanged into metal and I spun and locked his extended elbow joint across the hardened steel ladder. Full arm bar. He roared and flexed his massive bicep and pulled against me. He was incredibly strong, his suit of armor even stronger, but I had my feet planted on stone and my hip braced against steel and an enormous mechanical advantage. I yanked for all I was worth. And I was worth a lot. Something gave with the sound of an axle breaking. The Dzhaggernaut bellowed and I heard the giant knife clatter to the stone floor.
