Chiudibili Extrema Ratio:
Direttamente derivato da specifiche militari,questo apribile è stato sviluppato per sostituirenell'impiego un lama fissa.
Per raggiungere questo risultato sono stati impiegatimateriali robustissimi, alti spessori ed un sistema diapertura/chiusura solido e sicuro: il back lock.
Il coltello è dotato di sicura manuale che conferisce massima sicurezza nell'impiego e riduce in manieradrastica il rischio di chiusure accidentali.
La sicura, se inserita in chiusura, evita agli operatorimilitari o di polizia che nel caso di sottrazione il coltello possa essere rivolto contro di loro.

Materiali e lavorazioni:
Tutte le parti del coltello sono ricavate dal pieno da macchine a controllo numerico ad alta precisione mentre l'assemblaggio, l'aggiustaggio e l'affilatura sono condotte artigianalmente.
La lama è in acciaio inossidabile al cobalto N690,un acciaio dalle elevatissime caratteristiche di resistenza alle sollecitazioni meccaniche, capacità ditaglio, tenuta del filo e resistenza alla corrosione.L'arrotatura è piana e la durezza è di 58HRC.
Le guancette dell'impugnatura sono in Anticorodal, unalega di alluminio con elevate doti di resistenza alle sollecitazioni meccaniche ed all'ossidazione.
Il codolo, in N690 temprato, è un efficace frangi cristalli d'emergenza. Tutta la viteria, i perni e laclip sono in acciaio inox brunito. La lama, la leva edil codolo sono ricoperti con trattamento Testudo,molto resistente all'abrasione ed all'ossidazione.Le guancette sono anodizzate nere.

Notes: safety mechanism both in opening and closing

Directly derived from military specifications, this fold has been developed to replace a fixed blade in use.

To achieve this result, very strong materials, high thicknesses and a solid and safe opening and closing system were used: the back lock.
The knife is equipped with a manual safety device which confers maximum safety in use and reduces the risk of accidental closure in manieradrastica.
The safety device, if inserted in closing, prevents the knife from being turned against itself in the case of subtraction.

Materials and workmanship:

All parts of the knife are machined from high-precision CNC machines, while assembly, adjustment and sharpening are carried out by hand.
The blade is made of cobalt N690 stainless steel, a steel with very high resistance to mechanical stress, cutting capacity, thread strength and corrosion resistance. The grinding is flat and the hardness is 58HRC.
The grips of the handle are in Anticorodal, an aluminum alega with high resistance to mechanical stress and oxidation.
The tang, in hardened N690, is an effective emergency crystals. All screws, pins and clips are in burnished stainless steel. The blade, the lever and the shank are covered with Testudo treatment, very resistant to abrasion and oxidation. The cheeks are black anodized.
