Frequently Asked Questions
How long is the blade on the TUSA X-Pert II Titanium knife?
The blade measures 4.5 in / 11 cm and the knife measures 10 in / 25 cm overall. The drop point blade carries a straight edge, a serrated section and a line cutter for rope, line and webbing.
Why is the X-Pert II made from titanium instead of stainless steel?
The X-Pert II uses 6-4Ti (Ti-6Al-4V) titanium, which TUSA specifies for its high corrosion resistance. That matters most for divers who use the knife repeatedly in saltwater. The knife also disassembles, so you can break it down, rinse the components and reassemble it as part of routine cleaning and maintenance.
What colors and part numbers does the X-Pert II Titanium come in?
TUSA offers two finishes: Metallic Silver, listed as MS with SKU FK-940TI-MS, and Metallic Red, shown here as Metallic Dark Red, listed as MDR with SKU FK-940TI-MDR. Both are the FK-940TI, so the choice is about appearance and matching the rest of your kit.
How does the knife attach and how is it released?
The sheath uses a single button lock release, so the knife stays secure until you press the button, then comes free for quick access. An easy-to-adjust buckle and strap set the fit, allowing you to carry the knife on the leg or on a belt.
