Jens Ansø to focus efforts on his personal brand, Ansø of Denmark.

It’s an end of an era.

After nearly a decade of collaboration, GiantMouse Knives and Jens Ansø are parting way. As of 2025, Ansø will step back from GiantMouse to focus on growing his personal brand, Ansø of Denmark.

The designer has been a cornerstone of GiantMouse since its founding in 2015. Alongside fellow Danish designer Jesper Voxnaes (Vox) and American entrepreneur Jim Wirth, Ansø co-founded the brand with a mission to create exceptional knives that combine innovative design, premium quality, and fair pricing. His contributions to GiantMouse, particularly his collaborative designs with Voxnaes, have shaped the brand’s identity and earned it a loyal following in the knife-making community.

“This is a natural evolution that allows both GiantMouse and Jens to focus entirely on growing our respective brands, and we’re all excited about what’s ahead,” said Jim Wirth, CEO of GiantMouse, in a press release. “We’re grateful for everything Jens has brought to GiantMouse over the past nine years. As we move forward, Jesper and I are focused on shaping the future of GiantMouse, while Jens will be able to dedicate himself fully to Ansø of Denmark. We’re confident this step will allow both brands to expand in new ways and achieve the unique goals we each hold for our respective visions.”

Ansø expressed similar sentiments, reflecting on his time with the company.

“Co-founding GiantMouse with Jim and Jesper, and collaborating with Jesper on knife designs has been an amazing experience,” he said. “I’m very proud of what we’ve built together over the years. GiantMouse has become a brand that represents quality, innovation, and a strong connection with its community, and I’m honored to have been part of its journey.”

To honor Ansø’s legacy, GiantMouse will continue to credit products co-designed by Voxnaes and Ansø with the “designed by Vox/Ansø” designation in their product descriptions. This decision underscores the importance of their collaborative work and the lasting impact Ansø has had on the company’s success.

“We’re proud of what we’ve built together and can’t wait to see what the future holds for both brands,” Wirth added. “This isn’t goodbye—it’s simply the next step forward for all of us.”

In addition to building GiantMouse’s reputation, Ansø was part of a number of knife designs earning top honors at BLADE Show. In 2023, the GiantMouse GMX was voted Knife Of The Year, subsequently the company won 2023 Best Fixed Blade at BLADE West, 2024 Import Fixed Blade of the Year at Blade Show and 2024 Best EDC Knife at BLADE Show West.

With a career spanning over three decades, Ansø has built a legacy of innovative knife designs influenced by his background in industrial design, his love for craftsmanship, and his dedication to learning through trial and error. His passion for the craft and commitment to excellence continue to inspire the knife-making community worldwide.
