21,85 €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 dagger profile allows precise knife handling in tight spaces. The overall design is complemented by a textured rubber handle, which provides a secure grip even when wet and under operational stress.

Model 31699 is a functional EDC tool for users who value speed, precision and discretion in their daily equipment.
7Cr17MoV is a martensitic chromium steel, often referred to as an improved version of 440A steel. Its nominal chemical composition includes about 0.60-0.75% carbon (C) and 16.0-18.0% chromium (Cr), with additions of molybdenum (Mo) and vanadium (V) in smaller amounts. The higher chromium content provides very good corrosion resistance in typical environments. Carbon is responsible for hardness, which after appropriate heat treatment can reach about 56-58 HRC, which is sufficient for many applications. Molybdenum increases hardenability and improves resistance to pitting corrosion, while vanadium contributes to the formation of fine carbides, which increases abrasion resistance and allows the cutting edge to remain sharp longer. 7Cr17MoV steel is widely used in the mass production of kitchen knives, folding knives for everyday use (EDC), multi-tools and outdoor equipment, where a good combination of corrosion resistance, acceptable hardness and ease of sharpening is crucial .
Blade - made of 7Cr17MoV stainless steel dagger type provides good sharpness retention and moisture resistance. Black Titanium coating increases surface durability, minimizes glare and supports the tactical look of the tool. Blade's symmetrical geometry allows for fast, sure penetrations and precise cuts, while the compact format increases effectiveness in defensive applications. The design provides instant access and effectiveness in situations where reaction time is critical.
Handle - The textured rubber used for the Handle provides excellent grip regardless of conditions - even with wet hands or dirt. Ergonomic profiling promotes control of the tool, reducing fatigue during dynamic actions. There is a hole in the back of the tang for mounting a safety cable or key ring. Included is a nylon sheath with clip and MOLLE attachment , allowing for convenient concealed carry and quick access in any situation. The whole creates an effective tool for personal defense and tactical use, ready for action at any time.
