Wonders of the Lost Age had a great little chapter section on Utility artifacts like Fire Pearls (used as small makeshift lighters, or piercing ammunition for chemical bazookas), Windslave discs (panels of blue jade which can render heavy loads and cargo lighter, with increased weight limits as they get bigger), Thousand Comforts Lounge (luxury furniture which can shift shape and materials, such as a wooden stool to a metal throne), Sympathetic Elemental Scanners (summon an elemental and coax it into a relaxed state of dreaming elemental energies, and read its eddies for upcoming weather or geological events aligned to its element anywhere in Creation, like storms or earthquakes).
1e has the universal favorite in the Winterbreath Jar, which keeps anything inside it cold, while the Book of Bone and Ebony had some interesting things with Blood Apples (glass fruit which grows only during Calibration in the Underworld/shadowlands, when eaten allowing the user to physically 'die' and rise from her body as a ghost for 12 hours), Bloody Ice Combs (a disposable hairpin which conjures up a supernatural blizzard of snow and frozen blood for five minutes, up to a mile from where it was thrown into the ground and shattered), Drums of the Living Heart (skin-bound drums anointed with a targets blood, and beats in time with her heart to monitor vitals/wellbeing), Stones of Ten Thousand Tears (permanently remove chosen memories from a living person so they can be relived by the dead, typically as a trauma therapy tool), and Thirst-Quenching Pitchers (funnel blood into the jug, it becomes any beverage the holder has tasted before, though poisons don't count).
That's all I got off the top of my head.
