- 3D Spider Blue Titanium Steel, Blue Titanium 420 - a striking folding knife with a drop point blade coated with blue titanium and an openwork handle with a decorative spider motif. A collector's design with practical potential.

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.
The 3D Spider Blue Titanium Steel, Blue Titanium 420 is an original proposal from Herbertz, which balances between fine art and functional EDC knife. The distinctive design, including a metal Handle with a three-dimensional spider motif and a blade with a blue titanium coating, creates an eye-catching tool both in the collection, and in everyday use. The 420 stainless steel used guarantees resistance to corrosion and ease of maintenance, while light perforations in the back of the Blade reduce its weight and emphasize the artistic character of the whole. The surface finish gives the knife a deep blue sheen and an extra layer of protection. The Handle retains full functionality despite its artistic form - an openwork skeleton with geometric holes and pronounced profiling allows for a secure grip. The decorative application of a spider, integrated into the body, adds to the overall style bordering on fantasy and steampunk. The model is equipped with a clip and a cord hole, which makes it useful also outside the context of collecting.
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 - with drop point profile of 420 steel, valued for its resistance to moisture and ease of sharpening. The cutting edge, brought out with a flat grind, guarantees good performance in everyday tasks. Blue titanium coating adds durability, increases abrasion resistance and gives the Blade a unique decorative character. In the back of the blade there are cutouts, which reduce weight and complete the modern styling.
Handle - made of metal frame, the Handle is a combination of aesthetics and engineering precision. The openwork arrangement of geometric holes gives the whole a light and technical look, and the decorative spider figure with a tactile texture is the central visual element. A blue titanium coating covering the entire surface improves durability and protects against scratches. The whole is complemented by a carrying clip and a cord hole, increasing the functionality of the design.
