any mishap that may arise.
Extrema Ratio company manufactures their knives with quality materials and
Italian knife company Extrema Ratio offers excellent knives models for
divers. Extrema Ratio has spent four years of effort to develop its
technology in collaboration with the Military Dive Teams of the Italian
Special Forcesm, Civilian Underwather Operation Experts and Law Enforcement
Dive Teams. The result has been the Ultramarine diving knife. This is a knife
made of stainless steel N690 as well as the majority of manufactured Extrema
Ratio knives. It?s very hard steel, resistant to oxidation due to the cobalt
content it has. The knife blade of 6,3 mm. thick, has a length
of 150 mm.
together with the handle reaches a total length of 298 mm. The handle is made of
polyamide (nylon) to facilitate retention.
The Extrema Ratio Ultramarine knife has a
unique design that makes it perfect for use in diving activities.
Ultramarine diving knife combines quality and versatility. The aim of
Extrema Ratio has been to produce a functional tool for professionals to
avoid having to wear diving multiple utensils with varied functions. Thus,
the Ultramarine submarine knife can serve for multiple functions.
This is an ideal knife for use in
scuba diving activities. The material on the handle means that it is easy to
grip the knife even when wearing neoprene gloves. It also incorporates a
groove which allows you to use it on through bolts on shackles. The
Ultramarine knife includes a mooring rope which allows you to moor the knife
when you are working with it, without having to keep it in the cover.
The serrated section of the knife
allows you to cut cords or other materials
It is a useful tool for use in the
countryside, in forests or woodlands. The Ultramarine knife´s Extrema Ratio
blade is hard enough to cut through branches, shrubs and thicket, and can
come in useful for building refuges in the case of emergency, making fire,
or fashioning stretchers to transport someone who is injured. In addition,
as shown in the image above, the saw located at the end closest to the
handle makes it easy to perform tasks such as cutting cords or similar
materials in the event that the distal end of the blade becomes damaged.
Furthermore, the sharp part of the blade close to the handle can be used to
make precise cuts or even to carve.
The Extrema Ratio Ultramarine submarine knife is useful in the country, sea
and air (especially useful thanks to its design which avoids tangles in air
operations), but can also be of use to us in emergency situations thanks to
its characteristics. The hydrodynamic design of its sheath attaches it
perfectly to the body, thereby reducing the risk of tangles, and the design
itself also allows the user to decipher the orientation of the blade by
touch in surroundings of reduced visibility. On the other hand, the cover
also has a fast opening system which enables the extraction of the knife in
seconds. In situations of risk, thanks to the conical design of the
Ultramarine knife, it can be used as a device for breaking glass.

knife can also be handy in survival situations thanks to the design of its
handle. It can be dismantled to attach the blade to a pole and use the knife
as if it were a lance. For this purpose, the blade has also been made with a
matt finish allowing us to hide from strangers and threats. In addition, the
knife´s cover incorporates two sheets of diamond to sharpen both the main
blade and the cutter.
