- Herbertz CJH Black Fiberglass, Red HW, Black 420 - a modern EDC folding knife with a black coated 420 steel Blade and fiberglass-reinforced polymer Handle. Stylish design and everyday functionality in a compact format.

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.
Herbertz CJH Black Fiberglass, Red HW, Black 420 is a modern proposal from the German brand Herbertz, aimed at users who value ergonomics, functionality and dynamic aesthetics. The combination of a black stainless steel Blade with contrasting red accents and a textured Handle creates a knife that stands out for both its appearance, as well as its utility capabilities. The 420 stainless steel used guarantees corrosion resistance and ease of sharpening, while the black protective coating increases scratch resistance and reduces glare. The profile of the blade clip point provides good cutting properties, while maintaining a compact size. Handle made of fiberglass-reinforced polymer combines lightness with high resistance to mechanical stress. The profiled grip line and non-slip texture allow you to operate the tool confidently in a variety of conditions - regardless of whether you work with gloves, or bare hand. The presence of a clip, backspacer and cord hole increases functionality in the field. This is an option for those looking for a sturdy everyday knife with tactical character and practical design solutions.
420 martensitic stainless steel rich in 0.15% carbon, containing min. 12% chromium, which offers high hardenability in the 54-56 HRC range as well as strength, toughness, machinability and excellent corrosion resistance. The high carbon content produces chromium carbide compounds for wear resistance and edge retention after hardening. Due to its high hardness, the steel is suitable for manufacturing cutting tools, knife blades and medical instruments.
Blade - clip point, made of 420 stainless steel, providing resistance to rust and ease of maintenance. Flat grind improves cutting performance, and black protective coating protects against light reflections and increases the durability of the blade. Thumb stud opening allows quick and convenient one-handed operation.
Handle - made of fiberglass-reinforced polymer, combines low weight with high mechanical strength. The textured surface provides a secure grip, and red accents at the pivot and backspacer give the design a dynamic look. The shape of the grip has been adjusted to the natural position of the hand, and the presence of a clip and cord hole increases practicality in everyday use.
