Our Story

Hot Metal Knives (HMK) is a Finnish brand founded in 2019, dedicated to crafting high-quality, performance-driven knives that embody the perfect blend of tradition and innovation. At its heart lies a deep respect for the ancient art of blacksmithing, with inspiration drawn from both Finnish and Japanese knifemaking traditions. Each HMK knife is a testament to this philosophy, combining time-honored techniques with sleek, modern design for tools that are as functional as they are beautiful.

The story of HMK began years earlier, when founder and master blacksmith Thomas Rönnberg made his first knife sometime between 2005 and 2007. What started as a singular creation became the beginning of a lifelong passion. Over the following years, Thomas explored the rich tapestry of knife-making cultures across the world. This journey shaped the vision for HMK: to honor traditional construction methods, some of which date back thousands of years, while reimagining them for the modern era.

Crafted from Stories and Steel

At HMK, the process of creation is as important as the final product. Every knife begins its journey with carefully chosen materials, each with its own story. The oak may come from a whiskey barrel once used by the Helsinki Distilling Company. The antlers are collected from seasonal hunts in the expansive Finnish wilderness. Blades are made from repurposed materials like truck steel springs weighing over 80 kilos or wrought iron pieces dating back over 200 years, salvaged from flea markets. Even modern high-performance steels like m390 are given new life through repurposing.

Sustainability and Craftsmanship

HMK is committed to sustainability, ensuring that each component is responsibly sourced, often personally harvested. From curly birch saplings planted in 1999 to oak trees that have weathered centuries, the materials are transformed with care, preserving their natural character. Every knife is a blend of artistry, functionality, and ecological responsibility.
