ExtremaRatio - Misericordia - 4th Alpine Paratroopers Regiment - tactical knife
The Extrema Ratio Misericordia was adopted by the 4th Alpine Paratroopers Regiment which helped develop and test the product. It is a tactical fixed blade knife, extremely light and compact, it can be used both as a main knife or as a backup blade.
The blade is made of Böhler N690 steel, heat-treated to a hardness of 58 HRc, it is 118 mm long, 4mm thick and has a flat edge.
The profile is of the spear point type, with a full length fuller which makes the blade even lighter and with a false counter-thread at ¾ length. The blade is available with the classic Extrema Ratio MIL-C-13924 black finish.
The handle in fiberglass-reinforced nylon (FRN) features the classic Extrema Ratio recesses that make the grip safer and is fixed to the tang by means of a through screw.
On the rear end the handle flows connecting with a large ring, which allows the use of martial arts techniques and ensures a very solid grip to the hand, equipped with a "skull crusher" appendix in hard metal.
The overall weight of the knife is just 87g. Being a knife designed for professional use, much attention has been paid to ease of port, accessibility and extraction in case of need. The knife is secured to the sheath by a quick-release safety catch that can be easily reversed for use by left-handers.
The sheath is made of highly resistant Nylon, it is very versatile and two adjustable loops allow it to be fixed inside the loops of M.O.L.L.E.
The sheath is equipped with a conical invitation to facilitate the re-insertion of the knife while a simple pressure on the trigger safety allows it to be extracted quickly and instinctively.

* Checked and certified by our internal laboratoryThe SOG Recon Government S21 is an extremely rare variant of the Government model, produced between the 1990s and early 2000s, when SOG was among the world reference brands in outdoor and military cutlery. This version stands out for its dark blade finish.
Unlike the standard Government S13 in stainless steel, the Recon Government uses SK-5 carbon steel, required for the gun-blued treatment, not applicable to stainless steels. This makes it a technically different model.
Produced as an alternative variant of the series, today it is considered an extremely rare knife with almost no availability on the collector market.
Technology and materials
SK-5 steel blade with gun-blued finish that reduces reflections and protects the surface. Hardness 57-58 HRC for a good balance between strength and sharpenability. Black Kraton handle for a secure grip.
Solid construction with steel guard and pommel, consistent with the Government series for heavy-duty use.
