Small enough to sit unnoticed among your keys, the Whale Bottle Opener is a machined steel cylinder with a cap-lifting slot at one end and a hole through the body for a keyring. It stays hidden in your pocket and, like a whale, surfaces just when necessary.

Machined in England from solid stainless steel and finished with a 4µm tungsten carbide layer, 9x harder than stainless steel and usually reserved for high-performance cutting tools. It shrugs off the scratches of a lifetime spent among keys and keeps its deep, even black.
