Martinez Albainox Boot Knife Black ABS, Black 3Cr13Mov (32299)
- Boot Knife Black ABS, Black 3Cr13MoV - a compact tactical boot dagger knife with a black-finished dagger blade and ABS plastic handle. Sheath for belt or boot provides quick access and discretion.

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.

Its compact size, simplified design and classic geometry make this model a tool ready for urban, off-road and tactical conditions. The 3Cr13MoV stainless steel used provides corrosion resistance and simple maintenance, while the black coating enhances discretion and surface durability. Blade's symmetrical dagger-type blade works well in defensive applications, offering confident action with limited movement.

This is an ideal choice for EDC users, uniformed services and tactical enthusiasts looking for a functional, easy-to-carry backup tool.
3Cr13MoV is a martensitic chromium steel that has been enriched with molybdenum (Mo) and vanadium (V) to improve its performance properties. The typical chemical composition includes about 0.26-0.35% carbon (C), 12.5-14.5% chromium (Cr), 0.4-0.6% molybdenum (Mo) and 0.1-0.2% vanadium (V). The addition of chromium provides corrosion resistance, while molybdenum increases hardenability, high-temperature strength and resistance to pitting corrosion. Vanadium contributes to the hardness, wear resistance and fine grain structure of the steel. 3Cr13MoV is used for knives (often found in folding knives and hunting knives), medical tools and other applications where a good combination of corrosion resistance, hardness and strength is required. It is an improved version of 3Cr13 steel, offering better sharpness retention and overall durability.
Blade - symmetrical dagger double edge profile (sharpened on both sides)provides high penetration properties and precise blade guidance in the axis of grip - especially important in defensive situations. The blade, made of 3Cr13MoV steel, offers adequate corrosion resistance and easy sharpening, making it practical for everyday and emergency applications. The black coating increases resistance to micro-scratching and eliminates light reflections, reinforcing the tactical nature of the model. The sturdy construction provides rigidity and stability even in dynamic use, while the compact proportions and thin blade cross-section support quick, instinctive access to combat functionality.
Handle - made of durable ABS plastic, which maintains structural stability under varying environmental conditions. The textured surface improves grip and control of the tool, while the ergonomic molding promotes natural hand positioning. The crossguard on both sides prevents the hand from accidentally slipping toward the blade, increasing operational safety. At the end of the Handle there is a hole for a rope, allowing the installation of a safety device. The set includes a nylon sheath , adapted for mounting at the belt or shoe - a classic solution to promote mobility and discretion. The whole creates a compact, functional set ready for immediate use.
