Morakniv Risberg Heavy Duty (C) – Carbon Steel – 91 mm

The Morakniv Risberg Heavy Duty (C) is the most technically robust model in the Risberg series. This knife was specifically designed for users who put their gear through rigorous use during bushcraft, hunting, or intensive camping activities. Thanks to the switch to German carbon steel and a significantly thicker blade, this knife offers the structural integrity required for heavier tasks where a standard knife falls short.

The Risberg Heavy Duty is constructed with a focus on maximum mechanical resistance:

- Steel type: The blade is made from German carbon steel (C100S). This steel is known for its superior toughness and ability to achieve extreme sharpness that lasts longer than with stainless steel.
- Blade thickness: With a thickness of 3.2 mm, this knife is significantly stronger and stiffer, which is essential for tasks that place a lot of lateral pressure on the blade.
- Hardness: With a hardness of 57.5 HRC (Rockwell), the steel offers the ideal balance between edge retention and impact resistance.
- Grind: The cutting angle has been increased to 27° with a classic Scandi grind. This larger angle ensures a more durable edge that is less susceptible to damage during heavier work such as batoning or cutting hard woods.

This model stands out for its power transfer and functional stability:

- Improved Balance: The blade extends deep into the handle. This design ensures optimal balance and more direct power transfer from the hand to the cutting edge, enhancing control.
- Compact Powerhouse: Despite its robust specifications, the knife retains the compact dimensions of the Risberg series (total length 20.6 cm), making it a highly powerful tool that is easy to carry.
- Clip Point Geometry: The Clip Point shape of the 91 mm blade combines a strong spine with a sharp tip, making the knife versatile for both heavy-duty chopping and more precise cutting.
- Durable Handle: The ergonomic plastic handle provides a secure grip and withstands the mechanical forces generated during heavy use.

Due to the use of carbon steel, consistent maintenance is essential:

- Corrosion prevention: Carbon steel is not stainless and will oxidize when exposed to moisture. Clean and dry the blade immediately after each use.
- Oiling: Regularly apply a thin layer of oil (such as Ballistol or a food-safe mineral oil) to the blade to prevent rust. Over time, a natural patina will develop, which improves corrosion resistance.
- Sharpening: The Scandi grind is easy to maintain in the field with a flat whetstone. Due to the larger 27° angle, the edge is very forgiving during sharpening.
- Storage: Do not store the knife in a damp sheath for extended periods. Use the included plastic sheath for safe transport during your activities.

The Morakniv Risberg Heavy Duty (C) is a technically superior tool for the serious outdoor enthusiast. The combination of 3.2 mm thick German carbon steel and the modified cutting angle makes this knife an indestructible partner for heavy-duty work in the wild. The objective verdict is that, thanks to its outstanding toughness and power transfer, the Risberg Heavy Duty is the best choice for anyone looking for a compact knife that can handle any challenge.
