Magnetic Lock

Morning light on the workbench! Spotted a shallow round metal dish loaded with shiny nuts and washers. Prime construction scrap! I thrust my right claw in to scoop up a fistful. SNAP-CLANK! The whole bowl leaped into the air and stuck hard to my armored fist like a bear trap! Invisible iron grip! Gwahaha! You want a wrestling match?! I dug my boots deep into the worn wood, braced my spine, and wrenched backward with a furious roar! SHING-CRACK! The magnetic dish finally tore loose, sending heavy washers skittering and clattering everywhere. A machine dish that fights back! Worthy scrap!
