This vintage WWII-era knife was caked up with a massive amount of rust and grime. Lost & Restored shows us how they managed to remove the rust and bring this commemorative pocket knife from the U.S.S. Wasp back to life. We were surprised to see how many parts it had when it was fully disassembled.
What you’re looking at here is an old digital pinball game that dates back nearly four decades. TysyTube found the yellowed and badly-scratched handheld system on an auction site, and painstakingly restored it to like-new condition. Using that ice cube tray as a screw sorter is a brilliant lifehack.
With the advent of pay stations and mobile parking apps, meters are becoming a rare sight. But these coin-collecting dinosaurs still have some neat mechanical bits worth exploring inside of them, as Rescue & Restore shows as they down a 1960s Duncan meter and makes it like new again. That shiny red coat is a thing of beauty.
In this video from Odd Tinkering, they took a rusty old tabletop fan and make it look as good as new.
