Sport, Military and Collectible Knives | Coltelleria Collini

With thirty years of experience in designing professional knives, Extrema Ratio has developed a model designed for those seeking an everyday carry tool that combines functionality, lightness, and attention to detail.

The minimalist profile, clean lines, and light weight are not merely aesthetic choices for their own sake, but the result of a design focused on efficiency. Every element serves a specific purpose. Nothing has been added merely to impress; nothing is there without a reason.

The Dragonfly™ has been a staple in the Spyderco line for decades and continues to set the standard for those seeking exceptional cutting performance in a compact, four-finger grip format. This exclusive version features a blade made of CPM® SPY27®, a latest-generation steel developed in collaboration with Crucible® Industries and exclusive to Spyderco. An enhanced evolution of VG-10, enriched with cobalt, niobium, nitrogen, and higher amounts of carbon, molybdenum, and vanadium, it offers an extraordinary balance of edge retention, toughness, corrosion resistance, and ease of resharpening.

The PlainEdge™ blade with a flat edge and satin finish maximizes the qualities of this steel, while the FRN (glass-reinforced nylon fiber) handle, injection molded in the characteristic cobalt blue of the SPY27 family, ensures lightness and strength. The knife features a back lock mechanism and a reversible clip for deep carry, configurable on both sides in tip-up.

THE MAGIC BUTTON FOR HAPPINESS
Did you always think that happiness could not be achieved by simply pressing a button? You were wrong!

Don't confuse it with an assisted-opening or snap-open knife, it's a manual-opening knife that glides super smoothly thanks to a ball-bearing system, but Miura is above all a unique product in the industry thanks to the combination of the button lock type system combined with an integral handle made from solid machined titanium, features that together have never before been seen in industrial knives. These features, along with its fantastic design, led the Miura to win the 2022 Blade Show Imported Knife of the Year award in Atlanta.

NANO is the latest knife in the hi-tech family, an ideal partner for everyday activities.

The blade is made of CPM MagnaCut steel with satin finish equipped with the "ReF" (Removable Flipper system) applied on the new minimal lever, Double Crown ball bearing system and Solida titanium clip.

The titanium frame locking bar is reinforced with a hardened steel insert so that the titanium part will not be worn out by the rotation of the blade over time.
The clip, CNC-milled from a single piece of titanium, is reversible so it can be attached on the opposite side for left-handed users.

The removable Flipper system allows the user to decide whether the blade should have the trigger or not, which can be installed as needed or removed and replaced with the second "cap" screw.
