It all started with some sketches, a drawing, a wooden model, a first rudimentary design 3D-printed at home in blue plastic. At some point the project ran aground: it is too complex and difficult in so many parts. A year later, Confartigianato promoted the Artigenio Prize a competition for inventors sponsored by Mercedes. The blue plastic knife participates in the race and a few months later wins the first prize, a small sum for the project.Garbino and Repiks begin to think about the Lockin’ more seriously. Schiper’s engineering work, the high quality 3D print prototype, the patent and the creation of essential communication tools, bring Garbino back to work with steel, a small CNC milling machine and a lot of patience.Six months later the first metal prototype is born.
This knife, in which the various components form an articulated quadrilateral, opens and closes with a roto-translational movement. During closing, the handle separates and stretches making it possible to completely cover a longer blade (180mm). During opening, the handle is compacted to about 130mm, making the knife less cumbersome during use than with a fixed blade knife of similar size. The five-pin system, the open configuration, and the multiple contact surfaces of the components, make the knife exceptionally rigid and robust. The double safe lets the knife be ambidextrous and, with some practice, makes it possible to open and close with one hand.
The prototype knife is 320mm long when open, 200mm when closed and weighs 407g. It is almost entirely made in 440C, completely disassemblable in 47 components, with M3 fasteners in brushed or stainless steel. The two safes locks are made of 1.2mm Ti6Al4V and the handle features a specially created combination of cherry wood and carbon fiber. The knife also has a leather sheath prototype, ambidextrous, for the closed configuration.
