This is a special edition knife custom-made by Extrema Ratio of Italy for the British Commandos! The British Commandos were established during World War II. The harsh combat environment quickly forged this unit into one of the most elite forces in the UK. Brave and skillful, they excelled in completing various missions!
This knife uses N690Co steel developed by Böhler of Austria, which has high hardness, excellent wear resistance, and outstanding edge retention. The dagger-point blade, sharp as an awl, has powerful penetrating and armor-piercing capabilities (the bane of bulletproof vests).
