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.

blade has to be heavy enough to efficiently chop
branches and shrubs in order to make emergency
shelters, camouflage emplacements, stretchers,
