Description

The ULTRAMARINE is the result of four years of research and development, conducted by Extrema Ratio in collaboration with Military Dive Teams of the Italian Special Forces, Law Enforcement Dive Teams and Civilian Underwater Operation Experts. Units involved in underwater and amphibian operations use a variety of specialty tools. The main objective of the ULTRAMARINE Project is to substitute these different tools with one versatile utensil capable of performing the multitude of tasks that professionals in the fields are asked to perform in these difficult and challenging operations.

FIELD OPERATIONS

As with any respectable working tool, the mass of the blade has to be heavy enough to efficiently chop branches and shrubs in order to make emergency shelters, camouflage emplacements, stretchers, utensils or sector stakes.

  • The serrations facilitate cutting rope when the blade is dull from wear & tear.
  • The steel tang can be used as a hammer or glass breaking tool.

    UNDERWATER OPERATIONS

    To avoid damaging buoyancy or flotation devices during on-board operations with the exposed metal components of the knife, a flap was incorporated to cover the sheath & knife.

  • The slot in the blade was developed for use as a screw-pin shackle wrench.
  • The retention lanyard allows the user to work on equipment without having to sheath the knife.
  • The handle was designed with a plus sized grip & a special anti-slip material developed by Extrema Ratio to facilitate retention while wearing neoprene gloves.
  • With load positioned on the weakest end of the line cutter the blade withstands a load index of 45 kg (99 lbs).
  • On the blade with screw - pin shackle wrench slot, with load positioned in the center, the blade withstands a load index of 70 kg (154 lbs).
  • The sheath is designed to be sleek and hydrodynamic, with a close, tight fit to the body that reduces the possibility of entanglements.
  • The sheath also has a quick-release function that allows the knife to be rapidly drawn by simply pulling on the upper portion of the protective flap.
  • The protective flap uses special anti-wet snap fasteners that are specifically designed for water environments.
  • O-ring and retention system are disabled with a strong pull.
  • In panic or shock situations the user will have access to the knife.
  • The knife is designed with a specialized net & line cutting system for use in entanglement emergencies.
  • The knife is designed with reduced hilt guards to reduce the chance of entanglement and snaring while in use.
  • The design of the handle allows the operator to distinguish the orientation of the blade by feel in low light / no light situations.
  • The pointed tang was developed as a glass break device.

    SURVIVAL

    Besides being a good camp knife the ULTRAMARINE was designed so the handle could be disassembled, the blade attached to a pole and used as a spear.

  • The blade has been treated with a matt finish to reduce light reflection wile operating in hostile environments.
  • The sheath incorporates two sharpening diamond sharpening plates: one for the primary blade and the second for the net cutter.

    Supplied with the knife are 2 TEK-LOK belt support, 2 additional leg straps, 1 Lubra-Skin spray (100ml), 1 ink eraser, 2 additional O-ring, 1 additional TEK-LOK screw, 1 additional washer, 1 additional red Velcro strap.

      Outstanding knife quality manufacture but the design is flawed as I have never seen any shackle used underwater in 34 years off military and commercial diving that is small enough to benefit from the inclusion of the shackle groove in the blade for me this feature should be removed and what a knife this would become. A non magnetic version wold arouse greater military interest. (Posted on )
