ExtremaRatio - Frame Rock Titan - Blue Satin - folding knife
The Extrema Ratio Frame Rock is a new knife, based on the Ti-Rock project, a successful frame-lock knife made by Extrema Ratio in 2016 exclusively for Coltelleria Collini.
The Extreme Ratio Frame Rock is characterized by the titanium handle that offers great resistance while being very light. The integrity of the frame-lock locking system is guaranteed against wear by an easily replaceable hardened steel insert.
Unlike its drop-point predecessor, the Rock frame has a spearpoint blade 75 mm long, 6.0 mm thick, equipped with fuller for further lightening. The blade is made of Bohler N690 steel, heat treated to a hardness of 58 HRC. The same is available in black finish with DLC or satin finish.
To make the opening even more fluid and free of uncertainties, the blade rotates on ball bearings. This mechanism allows the user to adjust the force necessary to release the blade from the closed position.
The shape of the reversible clip allows a hidden port in the pocket, making the knife not visible from the outside. The large, solid handle and the well-proportioned blade allow this knife to tackle demanding tasks. Frame Rock weighs less than 200g, making it somewhat light for such a sturdy knife. It is supplied inside an ABS box.

ExtremaRatio - BF2 V Stone Washed Knife - Sailing Knife
This knife was designed and perfected in every detail for its primary use in the marine environment. The blade has a flat rounding that allows symmetrical cutting work with wider support. The tip, on the other hand, which is thick and durable thanks to the tanto version, allows greater penetration and a sharper, more precise cut. The stone washed finish process facilitates locating in the marine environment.
The structure of the handle, made of anodized anticorodal aluminum, features a design with milling in concentric circles and lightening and anti-slip perforations so as to facilitate rinsing from saltiness. A small slot is cut into the middle of the cheek piece to allow for tightening or releasing smaller shackles. BF2 V is equipped with reversible clip; adjusting screw retainer for closing and opening the blade; 70-mm. knot shock ankle with fastening mechanism; and correctable. The presentation of the BF2 V took place on the Amerigo Vespucci School Ship.

Currently I make a limited number of knives a year and participate in some exhibitions, where among other things I have won my first prizes:
in 2005 at LAME SOTTO I PORTICI in Romano di Lombardia (BG) I was awarded as "best table on display"
always in the same year at the CULTER-EXPO in Novegro (MI) as "best folding knife"
I was also ranked second in the competition organized by the magazine LAME D'AUTORE as the best fixed hunting blade
then in 2007 at "Scarperia" I won the third prize for best folding
but above all again in 2007, to my great satisfaction, I reached the degree of MASTER OF THE ITALIAN KNIVING CORPORATION, a recognition received at the first exam.
Presentation of the craftsman
Creating a knife by hand is what I consider a real art form.
The satisfaction of seeing an object that comes from one's own hands, that takes shape and reaches mechanical, artistic and aesthetic perfection is what pays me back the most for all the hours of work and effort it takes to create a knife completely. by hand.The passion for "cutting tools" has always been in me since I was a child and grew with me until the almost sudden decision to build my first knife myself, it was a "need", almost an inner necessity that I couldn't put off, my hands and my mind had to start creating, of course, what I had always been passionate about ... the knife!
I started at 40, in 2003, practically self-taught, I had no experience of manual work, but I had been a mechanical designer for many years and this allowed me to perfectly know the technique and all the various stages of mechanical processing.
Currently I am a member, with the rank of Master, which is the highest, of the Italian Knives Guild, an association recognized all over the world for the seriousness and above all quality of execution that all its members must maintain over time.
What I do now is what I consider my art form ..., to create "handcrafted, hunting and collectible knives".
They are knives made entirely by hand, only with an infinite series of files, a small drill for the holes and a sander for the concave grinding of the blades, nothing else!
I mainly make folding knives, which satisfy my desire to build perfect mechanical objects and perfection in the smallest details, even inside where they are not seen, is what distinguishes a knife created by hand, from one made industrially .The mechanics then must be made in the best possible way, without counting the hours of work, only in this way the final result is guaranteed.
Of course, over the years I have refined my technique and currently I have improved the mechanics even more by inserting a system of ball bearings on the blade rotation, which guarantee an absolutely perfect seal and allow the blade to close and open without the slightest friction. and with an incredible sweetness.
With regard to the blades then, I am experimenting with new types of hardening, which give hardnesses of 62-63 HRC and allow an exceptional edge hold and cutting quality for all types of use.
I make practically all the knives on an initial design of mine, they are all unique pieces made completely by hand down to the smallest details, one at a time, only in this way, in my opinion, a knife can be considered "artisanal".
Regarding the materials I use, I can say that for the blades I prefer RWL34 steel which is sintered from powders and guarantees the total absence of internal defects, sometimes I also use damascus, both stainless steel and carbon, for the uniqueness 'that give the knife, since each damask is always different from another.
For the handles, one of the most beautiful materials is the mammoth tooth, which can be found in a variety of wonderful colors, I also use fossil mammoth ivory, various briars, titanium and carbon fiber.
Most of the knives, however, are made entirely of steel, in order to then be engraved, always and strictly by hand, to transform the knife even more into a real work of art ...
