FIXED BLADE

SATRE

0 Reviews

Satre is a pocket-sized, light and extremely resistant fixed blade knife. Given its characteristics, it can be employed in a large variety of activities and fields, including survival and bushcraft, or it can be part of an EDC kit (Every Day Carry). It was designed in collaboration with Daniele Dal Canto, a Master Advanced F.I.S.S.S. instructor (Italian Federation of Sport and Experimental Survival). It can be worn as a neck knife thanks to its Paracord 550 lanyard. This way, it is possible to keep it vertical with the handle facing down. The pre-shaped Kydex sheath has eyelets, allowing to apply both lanyard and accessory holder. The ULTICLIP carry solution will be available from January 2022 (only on extremaratio.com). This allows to clip the sheath together with not only belts, but also pockets, trousers, jackets, shirts and t-shirts. ULTICLIP gives the possibility to position the knife both vertically and horizontally and allows a more accessible use for left and right handed. All three versions of the Satre come with the black sheath. Desert sheath can be purchased as an extra. The full-tang skeletonized structure allows the customization of the knife by using the Paracord as an handle cover. Satre is available in three versions with two different kinds of steel: The Black and Stone Washed versions are made with heat-treated Böhler N690 steel at 58 HRC. This material was chosen for its resistance to oxidation, for the durability of its edge and especially for its reliability, which has been proven over the years. The Black S600 is made with Böhler S600 steel instead. This steel is used for the manufacturing of metalwork and stamp creation tools. It has excellent qualities in terms of hardness, wear resistance and toughness thanks to the presence of molybdenum, tungsten and a significant add of vanadium to its chemical composition. The presence of cobalt stimulates the growth of small uniformly-distributed carbides, which enhance wear resistance. The Satre S600 is thermally and cryogenically treated in order to obtain an exceptional hardness of 64 HRC. This also makes it very resistant to wear and gives the edge a lasting sharpening. The Böhler S600 has 4.5% of chrome, which makes it oxidizable. For this reason, Extrema Ratio has chosen the new EXP DARK finishing. For its extreme hardness and resistance to wear and abrasion this steel is not easy to sharp. We suggest using our Double Grain Sharpener to be able to keep the edge of your Satre extremely sharp at any time. Free Shipping.

S-THIL

0 Reviews

The Extrema Ratio S-THIL Stone Washed is a backup tactical knife of monolithic construction milled out of a 5 mm (0.2”) bar of BOHLER N690 steel, developed in cooperation with designer Thilo Arnd Schiller. The spear point blade is heat treated to 58 HRC for best combination of edge retention and toughness. It has a false double edge to make it very effective in thrusting and piercing and has a full length fuller that flows elegantly from the blade into the handle. The blade is milled integral to the knife for better compactness and lightness, with minimum thickness yet with a pattern that reminds of the classical Extrema Ratio knife grip. This profile creates two small guards and a comfortable thumb rest to prevent the hand from slipping towards the blade. On the pommel there is a diamond shaped skull crusher and a slot for a wrist strap or for giving the knife a paracord grip wrap. The stamped nylon sheath has been designed to be extremely flat and very narrow, to keep it as compact as possible. Knife design makes the sheath ambidextrous and allows to insert the knife with the edge on the left or the right. The integral twin retention system is composed of four pressure elements that work one pair at a time, according to the direction the knife is inserted, while the textile nylon part has a button and a strap to secure the knife to the sheath. The tip of the sheath has a hole to allow debris or liquids to be expelled simply by blowing into it. The sheath can be used with belt clip, ULTICLIP or malice clip making it extremely versatile, while it is also possible to attach it to a M.O.L.L.E. webbing just by weaving paracord through it.

TASK C

0 Reviews

The Task series is planned for all day cutting works. The blade is partially symmetrical with flat grinding on both sides. The carving part in front of the hilt separates the cutting edge from the handle and it gives the index finger a position to rest while gripping the knife. This creates a grip position point closer to the cutting edge for better control while cutting and working with this blade. This characteristic combined with the finger waves on the upper part of the blade creates tactile resistance and avoid slipping on the sharpened edge. This way it is possible to carry out most of the cutting works using a higher strength and pressure on the knife itself.
