K25 Neck Knife Black/Red G10, Titanium 7Cr17Mov (32691)
- 32691 Black/Red G10, Titanium - EDC neck knife with full tang construction, titanium-coated 7Cr17Mov steel blade, G10 composite handle and Kydex sheath with chain.

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 32691 Black/Red G10, Titanium is a thoughtful choice for users looking for a rugged and compact tactical and survival tool with instant access. Based on full tang construction , it combines the functionality of an everyday EDC knife with features useful in field operations. The 7Cr17MoV stainless steel used is characterized by corrosion resistance and ease of sharpening, which is conducive to use in field conditions. The blade, coated with a titanium-based coating, reduces reflections and enhances mechanical resistance, which is important in tasks requiring discretion. An additional advantage of the model is the G10 handle, offering a secure grip even with wet hands. The kit comes with a molded Kydex sheath and ball chain, allowing the knife to be carried discreetly around the neck. The 32691 is a combination of minimalism, durability and ergonomics that will work well in the equipment of any user who relies on functionality and readiness.
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 corrosion-resistant 7Cr17MoV steel, offers a long cutting edge thanks to its high belly. This geometry works well for precise field tasks, as well as working in confined spaces. The use of a titanium-based coating not only improves durability, but also reduces the blade's visibility in confined conditions, enhancing its tactical qualities. Blade design allows for smooth and quick action in emergency and field situations.
Handle - made of G10, refined for ergonomics - profiling and finger undercuts ensure grip stability in all conditions. The material is characterized by resistance to moisture, changing temperatures and mechanical damage, which translates into service life in the field. The textured surface improves grip, and a cord hole allows you to secure or customize the knife to suit your needs. The compact size and light weight, combined with a molded Kydex sheath and ball chain, make the 32691 an ideal tool to carry around the neck - ready for use when time and reliability count.
