Our knives are built with the most current high tech manufacturing processes. Each Extrema Ratio knife is a blend of the finest materials available and a commitment to craftsmanship. When it comes to knives for survival use, one of the most important requirements is that the knife should be strong. Built to last.
Unfortunately, the manufacturing excellence and quality of our knives leads people to believe they are virtually indestructible. Sadly, this is not the case.
When the correct bending moment (torque) is reached also the toughest knife breaks.
Factors which determine the strength of a knife are its blade length, bladethickness and geometry, steel quality and technical design. Depending on what you want from a knife you should consider these qualities before you make your purchase, only then will you be able to make the optimal choice.
A long blade gives you more power, a thick, sturdy blade is stiffer,a well-treated high-end steel stands strain better and a well-designedknife is free from natural breaking zones. We leave no stone unturned in the search for Excellency.
In each knife we produce we do look for total performance solutions along with that style that defines all of our products entirely made in Italy.
What sets our knives in their own category of excellence is that every blade is free-hand ground, every knife is individually fitted, and every knife sharpened by hand. Precision and attention to small details, the use of special steel alloys, new techniques and knowledge and space technology materials make the difference.
With the objective of designing unique knives catered for the Armed Forces and Law Enforcement community and enthusiasts as well, Extrema Ratio has grown into a globally renowned brand recognized for dedication towards creating the next great combat knife. Our knives always put consumers and end users first.
All our products are built with high quality material and engineered in the best conditions and can be disassembled for easy cleaning and maintenance. This allows the worn parts to be easily replaced as well.As a private company, Extrema Ratio continues to expand into new horizons and push the limit further with each product unveiling.
