22,00 €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.

1.4028 (3H13, X30CR13) - is a martensitic, chromium group grade of stainless steels for hardening and tempering. The steel is included in the list of related counterparts - 0H13, 1H13, 2H13 and 4H13 - a group of materials without Nickel, containing an average of 13% Chromium, which are distinguished mainly by their carbon content in the chemical composition, and thus higher strength properties. The differences have a significant impact on the possibility of obtaining particular hardness ranges and levels of corrosion resistance, where 3H13 / X30Cr13 is a balanced choice between 2H13 and 4H13.
Regular maintenance of 1.4028 stainless steel (3H13, X30CR13) prevents deposits and maintains its luster. It also makes it easier to remove spots and tarnish. Cleaning should be done before there is a visible layer of dirt or fingerprints, so the danger of permanent discoloration of the steel surface is minimized. For cleaning, do not use agents that contain: chlorine, salt, acids and bleach.
