Early on as a child, Heimo Roselli became familiar with different kinds of tools as there were no services available and one had to do everything oneself at the home farm. Heimo was only about ten years old when he made his first knife.Later, as a young man, Heimo wanted to make himself a knife that he would feel comfortable working with. At first Heimo designed and made knives for his own and his friends’ needs. Gradually he became known as a skilled blacksmith in the village of Harmoinen in Kuhmoinen, Finland. As work became increasingly difficult to come by, he considered making a living out of knife manufacture using only his own unique designs. Since 1976, Heimo has been “living on the edge” as an entrepreneur and maker of knives of his own design.
In 1985, Heimo came across an interesting study by Stanford University. The study involved describing methods that dated back more than 2,000 years and enabled making factory-produced steels much more durable than the modern varieties. One of the most common names for these old, durable steel grades is ”WOOTZ”. Heimo concluded that since this age-old grade of steel was “birthed” by blacksmiths, so it was similarly his duty to acquire this skill via a “hands-on” process. After fifteen years of experimenting the results were impressive, and this particular grade of steel finally entered into industrial production with the help of a top researcher in the field. Nowadays it’s called ”UHC (Ultra High Carbon) WOOTZ” - a steel grade completely different from the rest. The present-day UHC steel by H Roselli is a non-alloy, ultra-high carbon steel. Its achievable hardness is 68 HRC. The ultimate tensile strength is 2500N/mm2. Combinations of corresponding hardness had not been previously detected, and the steel also had remarkable dynamic ductility. Optical equipment is unable to detect any grain boundaries in the steel, which enables excellent characteristics.
The special qualities of this steel are particularly evident in the incisiveness of the cutting blades and its resistance to wear - these features make it much better and of more uniform quality compared with its ancient predecessor.
That is why the “H Roselli UHC WOOTZ” knives are now known specifically as precision-forged, carbon steel instruments that maintain their durability and sharpness well.
For decades, the H Roselli products have been favoured by hunters, fishermen, and outdoors enthusiasts in particular. The ”UHC WOOTZ” knives have found their way to highly demanding conditions, such as crocodile hunting, where blade quality is crucial.
Hunting knife is Roselli's most popular knife and well suited for hunting and outdoor activities
A universal knife of a convenient size. The Carpenter knife is suited for whittling, cutting and DIY-work.
The Little Carpenter knife is suited for cutting and whittling, and it's also a great choice for a beginner or a child due to its blunt tip.
The Big Leuku is a large and heavy knife, somewhat resembling an axe in function. Due to its weight and design, it can be used to chop wood.
Slightly smaller and lighter than the Big Leuku, the Small Leuku is also suited for forestry work and cutting.
Made from Roselli's UHC-steel, Hunting knife is Roselli's most popular knife and it is well suited for hunting and outdoor activities. The shape of the Hunting Knife is protected.
