The Problue Talon Titanium knife combines function with durability. The titanium used for the blade gives the advantage of having a lightweight yet strong blade that is guaranteed to resist wear from rust, unlike steel blades which cannot ensure resistance. The knife uses two blade edge types: a straight-edge blade and a serrated edge which includes a line cutter. This gives the Talon Titanium Diving Knife a diverse set of applications underwater. The handle of the knife has an ergonomic shape to fit comfortably into the hand, with a corrugated design to give the handle grip. The knife also includes a small keyhole at the tip of the handle for attachment purposes.
