Made entirely of blackened stainless steel, it offers durability and resistance to wear and tear even with intense flipping training. The motif of skulls on the Handle gives the knife a dynamic, slightly aggressive character, fitting well with military and show aesthetics. The black-coated blade emphasizes the styling of the model and effectively masks traces of use, while the symmetrical form and proper balance facilitate rotary movements. The use of 3Cr13MoV steel guarantees easy maintenance and basic corrosion resistance. This is a model for balisong enthusiasts looking for a knife with a strong personality, intended for collector, training and recreational purposes.

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 - made of 3Cr13MoV stainless steel, which provides good corrosion resistance and simplicity of sharpening - features valued in knives for show and recreational use. The spear point profile allows precise blade guidance and dynamic movements, while maintaining an aesthetically pleasing balance of the silhouette. The black coated finish gives the Blade a matte, tactical look and reduces the visibility of scratches. The opening system is based on the classic balisong mechanism, with two arms rotating around an axis. The stability of the design is supported by the latch mechanism, which locks the blade in the closed or open position. Blade of the 02278 model combines style with utility, offering smooth operation and consistent visual aesthetics.

Handle - was made of blackened stainless steel, which ensures durability and appropriate structural weight. Its symmetrical form promotes even balance, making it easier to perform tricks and turns. The entire blade is covered with a motif of skulls, which distinguishes the knife visually. Despite the lack of aggressive texture, the contours of the arms provide basic comfort in use. The design does not include a clip or cord hole, which confirms its show and training nature. This Handle is designed for users looking for a visually strong balisong with good control and distinctive styling. Comes with a carrying case for carrying and storing the knife.
