The Pit Viper – Strike Fast, Strike True, Nature’s Perfect Predator!
The pit viper moves silently, striking without warning and retreating before its prey senses the attack. Its curved fangs, heat-sensing pits, and lightning-fast reflexes make it one of nature’s most efficient predators. The viper calculates every movement with minimal effort and designs every strike for maximum impact.
This deadly efficiency inspired one of the Philippines’ most formidable hand-to-hand combat weapons—the Pit Viper Blade. Like its namesake, this weapon features a curved, razor-sharp edge designed for quick, controlled strikes. Filipino warriors relied on this design for close-quarters defense, where speed and precision meant survival. The inward curve mimicked the snake’s bite, allowing users to hook, cut, and control with a seamless flow.
The Pit Viper’s design emphasizes grip, control, and adaptability. Its ergonomic handle ensures a firm hold, while the curved blade slices with unmatched efficiency. Like the snake strikes precisely and retreats to safety, this weapon allows the user to move fluidly, never staying exposed for long.
Born from nature and refined through centuries of Filipino craftsmanship, the Pit Viper symbolizes survival, strength, and precision. Master the strike, control the encounter, and embrace the spirit of the Pit Viper.

P:akal Grip

Sak-Sak Grip
Pakal vs. Sak-Sak Grip: Mastering Knife Handling for Close-Quarter Combat
The Pakal grip (ice-pick grip) is a method of holding a knife in a reverse grip (blade pointing downward) with the edge facing inward (toward the user). This grip optimizes powerful slashes, ripping motions, and thrusts in close-quarters combat.
In the Sak-Sak grip, the user holds the knife in a natural forward grip (blade pointing upward) with the edge facing outward (away from the user). It is used in stabbing, slashing motions, and deflecting attacks in close-quarters combat.

Care Tips for Your Filipino 425 Pit Viper Knife
Always hand wash and dry your knife to keep it free of debris and rust free. Avoid dishwashers, as high heat and strong soap can weaken materials and dull the blade. To maintain the edge, use a quick sharpener for minor touch-ups and a sharpening stone for deep maintenance.
Regularly applying 100% food-grade mineral oil prevents rust and keeps the blade working smoothly. Mineral oil also reduces friction and wear, helping knives with moving parts work correctly.
For long-term storage, thoroughly wash and dry the knife, apply mineral oil, wrap it in plastic, and store it separately from the sheath. These steps will keep your knife in excellent condition, ready for any adventure.
