These basic folders were developed by Extrema Ratio in response to a demand from Extrema Ratio owners for lighter EDC folders.

Added to these basic folders is the Extrema Ratio Resolza. This folder has a proud history. Developed in Sardinia centuries ago and used for everything from everyday work to the battlefield. The updated Extrema Ratio Resolza captures this well-regarded traditional folder using modern materials and old world craftsmanship.

Another addition is the Extrema Ratio modern adaptation of the straight razor originally used for shaving and then self-defense the T-Razor. Crafted from modern materials and modified for today's demands.

These basic folders are streamlined and lighter in weight; designed to be used mainly as the necessary utility knife that you call on frequently for everyday chores. All of these folders are excellent EDC knives with the high-quality and durability that Extrema Ratio knives are known for.
