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.

Blade with recurved trailing point profile , covered with a durable print in shades of blue, attracts attention and ensures smooth cutting. The 3Cr13Mov steel guarantees corrosion resistance and ease of maintenance, making the knife also suitable for light EDC use. An additional flipper makes it easy to open with one hand, and the flat grind improves cutting properties. The Handle is made of blackened steel shoulders with blue ABS inlays, which provide a comfortable grip, reduce weight and emphasize the modern character of the knife. Latch lock at the end of the arm allows stable locking of the blade in the closed or open position - a solution essential in any balisong design.
Balisong / butterfly / batangas / taal / butterfly - among the various types of knives, one stands out for its particularly impressive handling. This is the balisong butterfly knife, also known as “butterfly” or “bali”. Its history can be traced back to the 18th century Philippines, where it served not only as a practical tool, but also as an effective weapon for self-defense. Although the exact origin of the balisong remains shrouded in mystery, it is traditionally associated with the village of Balisong on Batangas Island. Its name in Tagalog means “broken horn,” which accurately reflects the knife's distinctive design. It consists of two handles that rotate around the Blade, resembling the movements of a butterfly's wings. Balisongs instantly gained recognition among Filipino warriors, gaining status as the national weapon. Their efficient opening and closing required extraordinary dexterity, evolving into an art form known as “flipping.” In the twentieth century, butterfly knives reached the West, gaining popularity among soldiers, sailors and enthusiasts of spectacular tricks. Today, despite the fact that in many countries their possession is subject to legal restrictions, balisongs continue to fascinate with their extraordinary agility and rich tradition.
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 - the curved, recurved trailing point type offers aggressive geometry and a large cutting surface, resulting in high functionality and an attractive appearance. The material of the blade is stainless steel 3Cr13Mov, ensuring ease of sharpening and weather resistance. The print in blue tones enhances the visual impact and gives the whole thing a unique style. An additional flipper promotes fast, intuitive opening, and the flat grind improves performance.
Handle - steel construction with black finish and blue ABS plastic inserts, which improve ergonomics and aesthetics. The ventilated structure reduces weight and improves balance, which is important for training and tricks. Latch lock in the back of the Handle allows the blade to be securely locked in both positions. All designed for dynamic use, collectability and striking presentation.
