The Viper Cutlery Ten model was designed by Fabrizio Silvestrelli. The Ten turns to the evolved user, that requires the mechanical operation to be perfect, regardless of time and wear. The heart of the Ten is its particular hybrid spring: the elastic element is made of titanium, to provide maximum elasticity, while the contact one is made of steel, for greater durability. Three screws allow the adjustment of the coupling between the liner and the heel of the blade, completed using a grain for the micro-regulation. The reduced size and weight, in addition to the provision of a practical opening flipper, make the Ten a great everyday companion.
