235,20 €This product is intended for use only by adults with knowledge and experience in handling sharp cutting tools. Improper use of the knife can result in serious injuries. The blade is extremely sharp and can easily cut through skin and tissue; therefore, extra caution should always be exercised while cutting, and hands should be kept away from the cutting edge. To prevent the knife from slipping, it is recommended to cut on a stable, non-slip surface and avoid excessive force, which may cause uncontrolled blade movement.
Leaving the knife on the edge of a table, countertop, or in easily accessible places—especially where children are present—poses a significant safety risk. The knife should always be properly secured after use, ideally by placing it on a stable surface or storing it in designated knife blocks, protective sheaths, or magnetic strips. The knife should never be used for tasks it is not designed for, such as opening cans or prying objects, as this can damage the tool and lead to dangerous accidents.
A dull blade increases the risk of injury, as it requires more force and is more likely to slip from the material being cut. Therefore, it is essential to sharpen the knife regularly to maintain optimal sharpness. Additionally, proper cleaning and drying of the knife are necessary to prevent corrosion and bacterial growth. Periodic inspection of the handle and blade is recommended to check for cracks, chips, or looseness. If any damage is detected, the knife should be repaired or replaced immediately.
When using the knife, focus solely on the task at hand—avoid talking on the phone, watching television, or other distractions while cutting. Ensure proper lighting in the workspace for better visibility and control. Please note that some countries or regions have laws restricting the ownership and carrying of knives. Before purchasing or using this knife, verify that its use is legal in your location according to applicable regulations.
Following these safety guidelines will help ensure safe and effective knife use, minimizing the risk of accidents and extending the lifespan of the tool.
KB Knives Mosquito Flame Titanium, Satin M390 by Dudnik Design (KB409B) is a premium EDC folding knife featuring a Drop Point blade, Böhler M390 steel, and a Flame Ano titanium handle.
KB Knives Mosquito – a titanium folding knife designed by Dudnik Design
KB Knives Mosquito Flame Titanium, Satin M390 by Dudnik Design (KB409B) combines the slim design of an EDC folding knife with the distinctive finish of a Flame Ano / Diamond Milling titanium handle. The Dudnik Design model features a Drop Point blade, a Frame Lock, and ceramic ball bearings, creating a folding knife with a technical character and smooth operation. Diamond milling gives the handle a dynamic texture, while the flame anodizing highlights the model’s collectible appeal.
The blade is made of Böhler M390 powder steel, which has undergone vacuum heat treatment and a cryogenic process. A hardness of 60–62 HRC ensures long-lasting sharpness, and the Compound grind combines multiple cutting edges, balancing cutting efficiency with adequate blade strength. The Satin finish refines the blade’s profile and complements the titanium hardware. Opening via thumb studs ensures comfortable, one-handed manual operation.
Böhler M390 steel Drop Point blade
The Drop Point profile offers a strong tip, predictable cutting control, and versatile geometry suitable for everyday utility tasks. It performs well with cardboard, ropes, packaging, plastics, and tasks requiring smooth blade guidance. The Compound grind allows for varying properties across different zones of the blade, enabling the edge to perform efficiently while maintaining stability under heavier pressure.
Böhler M390 is a premium powder steel, valued for its excellent corrosion resistance, high wear resistance, and long-lasting sharpness. Vacuum treatment and cryogenic annealing help achieve stable material properties at a hardness of 60–62 HRC. In practice, this means a blade well-suited for intensive EDC use, where edge durability and less frequent sharpening are key.
Flame Ano Titanium Handle and Frame Lock
The handle, made of Titanium, ensures high rigidity, mechanical resistance, and a favorable weight-to-durability ratio. The Flame Ano / Diamond Milling finish gives the surface a distinctive, multi-tonal appearance and a technical texture. The titanium backspacer and clip in the Flame Ano finish maintain the material consistency of the construction, while the sandblasted pivot and screws complement the folder’s precise character.
The Frame Lock utilizes a spring-loaded section of the titanium handle to stabilize the blade when open. Ceramic ball bearings ensure smooth pivot operation, while thumb studs allow for controlled, manual opening. The right-side, tip-up titanium clip facilitates everyday carry in a right-hand pocket, and the included Pouch protects the knife during transport and storage.
