Extrema Ratio is proud to offer a folder that is one of the “most famous traditional knives” of Italy. The Resolza was first produced in Sardinia and dates back to the mid-nineteenth century. (Sardinia is Italy's second largest island.) The Resolza was used by the island farmers and shepherds for numerous daily activities. Not only was it a necessary utility knife but these knives were carried by the owners when they were called to war.

Dimensions and proportions for the original Resolza are retained. Extrema Ratio's Resolza is a classic design with an elegant blade. Stylistic. Modern materials and technologies are applied by Extrema Ratio to create this Resolza. Beautiful to your eye and comfortable to your hand.

This Resolza is a blending of the famous Sardinia knife with Extrema Ratio's modern craftsmanship. A traditional utility knife is redefined into an exceptionally fine, modern EDC.


Extrema Ratio has retained the unique blade style of the original Resolza. In following the traditional design, it does not have the thumb studs you commonly find on other Extrema Ratio folders. This model has a black handle and a stone washed blade.


The handle is redesigned. This Resolza has a shaped handle that is entirely different from the handles Extrema Ratio normally designs for its folders. It has a very long, slender handle with inserts to give you a better grip. In following the original Resolza design, the folder does not have a clip. This is a knife designed to be carried undetected in your pocket.


The Resolza has a liner lock.
