Accompanied by quick-adjust rubber leg straps, the X-Pert II Titanium series stands as the ultimate lifetime safety companion for demanding technical, wreck, and ocean diving operations. Knife Features Premium Ti-6Al-4V (Grade 5) titanium blade provides extreme structural hardness and absolute rust immunity Classic drop-point tip geometry engineered for precise piercing, probing, and clean slicing Multi-edge layout combines a standard razor-straight edge, an aggressive serrated section, and an integrated line cutter notch Advanced ergonomic grip with a textured anti-slip overlay for maximum control in gloved hands Rugged, impact-resistant sheath with a rapid single-button thumb lock release system Heavy-duty quick-adjust buckles and high-stretch rubber leg straps for stable calf or thigh mounting Blade Length: 4 1/2 inches / 11 cm Overall Length: 10 inches / 25 cm Colours Available: Metallic Red (MDR), Metallic Silver (MS) Technology TI-6Al-4V (GRADE 5) TITANIUM ADVANTAGE The blade is precision-crafted from elite Ti-6Al-4V titanium alloy, a structural compound widely utilized in aerospace engineering for its extraordinary strength-to-weight ratio. Because titanium lacks iron, it is completely incapable of rusting or oxidizing in saltwater environments, ensuring the knife requires no post-dive oiling or meticulous chemical maintenance while remaining significantly lighter than traditional steel counterparts. COUNTERWEIGHTED BI-MATERIAL GRIP The handle is constructed with an advanced ergonomic rubberized mold shaped to fit comfortably and securely within a palm. To offset the extreme lightweight nature of titanium and preserve perfect tracking mechanics, a solid metal counterweight is embedded within the pommel button, optimizing the knife's center of gravity to deliver maximum leverage and striking power when cutting through dense materials. SINGLE-BUTTON RAPID RELEASE SYSTEM The modern locking sheath features a precise mechanical lock that catches the knife handle automatically upon insertion. This ensures the knife remains firmly anchored through heavy surf or tight navigation. A single-button thumb release mechanism allows the diver to deploy the tool smoothly and rapidly with one hand in high-stress or entanglement scenarios.
