Detailed analysis of properties and features
The blade is made of HV5 steel. The knife is based on a blade made of tool steel HV5, characterized by high hardness (65 HRC), outstanding wear resistance and the ability to maintain the sharpness of the cutting edge for a long time even with intensive use. HV5 steel is especially appreciated for work where a clean and easy cut is important, resistance to blunting after prolonged loads and high strength with a low blade thickness (2.4 mm). However, like most tool steels, HV5 tends to corrode with prolonged contact with moisture. After use, it is advisable to wipe the knife dry and avoid storage in humid conditions.
The handle is made of stabilized Karelian birch. The handle material is carefully crafted and stabilized Karelian birch with a unique amber-purple pattern. Due to the stabilization, the wood does not absorb moisture, does not swell or crack even with sudden changes in temperature and humidity, which guarantees durability and comfort during use. The ergonomic shape with a length of 120 mm ensures a secure grip in both dry and wet hands, and the natural tactility and pleasant warmth of natural wood make working with the knife especially enjoyable even with prolonged use.
The shape of the Clip-point blade (length 142 mm, width 30 mm) has a pronounced tip and a beveled butt line: This is an ideal option for precision work (woodwork, butchering fish and poultry, skinning, universal tasks at home and outdoors). Clip-point is a combination of sharpness, controlled cutting edge and versatility. The 2.4mm thickness helps to achieve a sharp, aggressive cut while maintaining sufficient strength for most household and field tasks.
Optimal tasks and applications
This knife is an excellent choice for hunting (cutting, skinning), fishing (milling, fish preparation), tourism and bushcraft (woodwork, cooking, making precise cuts). Due to its high aesthetic and collectible qualities, the knife is especially desirable for collectors and connoisseurs of unique handwork — each handle does not repeat the previous one due to the natural birch pattern.
The secure grip and minimal tendency to slip make this knife safe in wet and cold conditions. The natural handle with special stabilization technology stands out favorably for its durability against the background of ordinary wood.
Advantages and limitations
- Advantages:
- The blade made of HV5 (65 HRC) keeps sharpening for a very long time and is resistant to wear even under heavy loads.
- High wear resistance and strength of steel, confident and clean cutting.
- The ergonomic handle made of stabilized Karelian birch is not afraid of humidity and temperature fluctuations, and is extremely pleasant to the touch.
- The Clip-point blade shape is versatile — it handles precise and delicate tasks, and is great for hiking and hunting.
- Handmade knife — each piece is individual and has a special aesthetic.
- Genuine leather scabbard provides safe and stylish storage.
- Limitations:
- Despite its high hardness and wear resistance, HV5 steel requires maintenance: prolonged exposure to moisture is not recommended — the knife must be thoroughly wiped after use.
- It is not suitable for heavy power work on bones and metal (there is a risk of chipping the cutting edge during improper operation). Due to its high hardness, steel is more difficult to sharpen, requiring the use of special abrasives.
Care recommendations
To maintain its sharpness and aesthetic appearance, it is recommended to wash and thoroughly wipe the blade after each use, and avoid prolonged contact with moisture and acidic environments. Do not use the knife as a screwdriver or crowbar. Diamond or ceramic tools are preferred for sharpening. The handle does not require special care due to the stabilization, but you can use protective oils for wood from time to time.
A brief recommendation
This knife is the perfect choice for hunters, fishermen, hikers, and collectors who value durability, sharpness, and handmade aesthetics. It is especially valuable for those who appreciate the combination of a unique handle pattern and high working qualities. It is not recommended for rough work on bones, metal surfaces or people who are not ready for regular maintenance of carbon steel.
