What started as a concept shared by Tumbler on social media caught Liquid Death's attention and evolved into an unexpected limited-edition product.
SEATTLE (October 20, 2026) – Dull knives, your days are numbered. Tumbler, the brand on a mission to make the kitchen beautifully simple, and Liquid Death, the healthy beverage platform and one of the fastest-growing non-alcoholic brands, are teaming up to bring “Death to Dull Knives” to life with the launch of the Tumbler x Liquid Death Limited Edition Pro Knife Sharpener.
The idea originated with Tumbler, which developed an early concept and shared it on social media before there was an official licensing deal in place. The post caught Liquid Death's attention, setting the stage for the two brands to bring the limited-edition product to life.
The $159 limited-edition release features a black Tumbler Pro with gold sharpening discs, a coffin-shaped magnetic knife holder and custom coffin packaging, all brought together under the “Death to Dull Knives” concept. Beneath the bold design is the same simple hold-and-roll sharpening system Tumbler is known for, designed to sharpen knives in minutes without the guesswork often associated with traditional sharpening methods.
“Liquid Death and a rolling knife sharpener sound like an unlikely match until you realize both brands are trying to make everyday products impossible to ignore,” said Danielle Mateo, Head of Partnerships at Tumbler. “That's what made the idea click.”
The launch also marks Tumbler's first time teaming up with another brand on a limited-edition product.
The Tumbler x Liquid Death Limited Edition Pro Knife Sharpener is available beginning October 20, 2026, for $159 at tumblerware.com/liquid-death.
