Collection: Ultra High Carbon steel knives

Extreme sharpness and unmatched cutting power

Roselli’s Ultra High Carbon (UHC) steel  knives are the result of decades of research and development by Heimo Roselli. Unlike ordinary knife steels, UHC steel contains an exceptionally high carbon content that forms microscopically hard carbides inside the blade. These carbides are nearly as hard as diamond, giving Roselli UHC steel knives their legendary cutting ability, long-lasting edge retention and extreme sharpness. With UHC steel, you sharpen less and cut more.

For precision in every environment

The UHC steel collection is built for serious outdoor users who demand elite performance from their tools. These knives deliver precision and control whether used for hunting, fishing, carving, woodcraft, camp work or general survival tasks. A UHC steel edge bites clean through wood fibers, game hide and tough materials with effortless accuracy. If you want total cutting performance, nothing compares to UHC steel.

The benefit of UHC steel

Through a unique heat treatment developed exclusively by Roselli, UHC steel achieves a hardness far beyond conventional carbon steels while remaining tough enough for outdoor use. The result is a blade that holds its edge significantly longer than standard knives. This is steel built for those who expect more from their tools, more sharpness, more durability, more performance.
