Martinez Albainox 31801 Throwing Knife Set 3 pcs. Black Paracord, Satin 3Cr13Mov
- 31801 Throwing Knives Set (3 pcs) - a set of classic throwing knives with full tang construction, spear point blade and cord wrap handle. A modern interpretation of Japanese tradition in a practical training edition.

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.
31801 Throwing Knives (3 pcs) draws on the Japanese school of combat, combining classic form with the functionality of a modern training tool. Inspired by the weapons used by shinobi and martial arts adepts, the Kunai knives in this edition are designed with accuracy, durability and convenience in mind. Each piece is made from a single piece of 3Cr13MoV stainless steel, which ensures high resistance to overload and damage during intense training sessions. The spear point profile guarantees symmetrical flight and good penetration, while the satin finish surface reduces light reflections and masks traces of use. The Handle has been laced with durable nylon cord wrap, improving grip and allowing personalization. The end ring allows dynamic retrieval or attachment of a pendant. The set comes with a practical case made of ballistic nylon, accommodating three knives in separate compartments, with the ability to be clipped to the belt. The Kunai set is an ideal choice for both beginners and experienced knife-throwing enthusiasts - durable, balanced and ready for action.
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 - each of the knives is equipped with a blade with a symmetrical spear point profile, suitable for rotary and non-rotary throwing techniques. The blade is made of corrosion-resistant 3Cr13MoV stainless steel, which stands up well to repeated impacts and is easily sharpened. The lack of sharp cutting edges increases training safety, and the symmetrical grind promotes even weight distribution. The satin finish gives the overall blade a utilitarian look and reduces glare. Thanks to the well-chosen geometry, the knives maintain flight stability and perform well both on the sports track and in recreational throwing.
Handle - is an integral part of the monolithic full tang construction , continuing the line of the blade without additional grips. To improve grip, a cord wrap made of durable nylon, resistant to abrasion and moisture, was used. The ringed tip allows for dynamic handling and allows for the attachment of a cord or pendant, harkening back to traditional utility techniques. The symmetrical grip geometry promotes versatility and adaptability to different throwing styles. The set includes a case with compartments and a loop, which allows vertical attachment to the belt and safe storage of the entire set.
