In the MCU's Avengers: Age of Ultron, the genocidal android takes a moment to criticize Captain America's shield, decrying that the ultra-rare anti-metal Vibranium has been used "to make a Frisbee." If that got on the villain's nerves, then one piece of merch for his own movie would infuriate him beyond belief.
Able to absorb and redistribute energy, Vibranium has peerless uses in advanced technology and is almost indestructible. Wakanda built its self-sustaining economy on the metal, and it is the material used in many of the Marvel Universe's most unbeatable weapons. Of course, its powers make it incredibly effective as a shield in the movies, but it's understandable why an AI obsessed with creating the perfect body would see the world's rarest and most advanced material used to block bullets and be frustrated.
In 2015, Marvel released Avengers: Cutting Edge - a comic which gave the backstory of its Avengers Gillette razor line, which was produced as a tie-in for the release of Avengers: Age of Ultron. Each razor is based on one of the iconic Avengers, with models offering tribute to Thor, Captain America, Iron Man, and Hulk. In the world of the comics, the razors are constructed using high-level tech - Thor's razor is keyed to its owner's DNA so no-one else can lift it, Hulk's razor has stress-triggered sensors, and Captain America's razor includes a shield cartridge made entirely of Vibranium.
The Avengers Razors Have Powers in Marvel Canon
The story of the comic sees Tony Stark explain that he's experimenting with bringing Avengers-quality tech to everyday consumers, however in Marvel lore, it's hilarious that rare materials like Vibranium or a miniature arc reactor would be used to create razors. Villains have committed elaborate heists for this technology, which even Ultron - who has conquered entire planets - covets for his personal use, and yet in Avengers: Cutting Edge, Tony decides to commit it to getting the best shave possible. It's even shown that he's working on further models, with Black Widow's razor currently breaking the legs of anyone who uses it, and Hawkeye's projectile razor proving a threat to anyone in its vicinity.
Ultimately, Avengers: Cutting Edge remains an odd curio that fans can regard with affection, but given the nature of Marvel's multiverse, the comic does mean that in some reality - perhaps even Marvel's main universe - Iron Man dedicated Asgardian uru, unstable molecules, and Vibranium to creating a line of consumer products. Strangely, any hero or villain who managed to take ownership of the Avengers' Gillette line would be walking away with some of the greatest tech and treasure the universe has to offer - a haul worthy of Ultron, even if he'd likely be driven wild by its existence.
