Here’s how Roselli turns raw Finnish steel into knives that are trusted by hunters, outdoorsmen, and knife enthusiasts worldwide.

Shaping steel with precision and purpose

In a world of factory-made blades, Roselli stands as a beacon of true craftsmanship, where steel isn’t just shaped but born. At the heart of Roselli knives is our Ultra High Carbon (UHC) steel – a material developed by Heimo Roselli himself, combining decades of dedication, research, and expertise. This unique formula is the result of relentless innovation and a deep understanding of metallurgy, inspired by Finland’s heritage of craftsmanship and resourcefulness. Here’s how Roselli turns raw Finnish steel into knives that are trusted by hunters, outdoorsmen, and knife enthusiasts worldwide.

The process: How we craft our UHC steel

Each Roselli knife is crafted through a meticulous, multi-step process to ensure maximum performance and durability:

1. Custom casting and rolling
We start with a brick of Finnish steel, specially cast to our exact specifications. The steel is then rolled multiple times, each under carefully managed temperatures to achieve the right characteristics for further processing.

2. Precision cutting and pre-grinding
After the rolling process, each blade is precisely laser-cut and flat ground to its precise thickness. This stage also includes pre-grinding, crucial for the blade before further refinement.

3. Hardening and stress-relieving
The blades are hardened and tempered under carefully controlled forms. This is a critical step in UHC steel production, ensuring the blade achieves the correct balance of hardness and flexibility. Afterward, each blade undergoes rigorous testing to meet our exacting standards.

4. Grinding and polishing
The blades are once again flat ground to remove any residue from the hardening process and to smooth the surface, perfecting the blade’s finish.

5. Surface treatment and etching
To protect against corrosion, the blade is etched in acid, creating a natural, durable layer that enhances the steel’s resistance to rust.

6. Assembly and finishing touches
The blade is paired with a handle made from waterproof curly birch, carefully hand-stained and oiled for long-lasting beauty and function. Finally, the knife is placed in a high-quality leather sheath.
