Vernantin is the name given to the famous switchblade knives of the Vernante craft traditional with bone handle and hand-forged tempered steel blade. The originality of the knife lies in the fact that it was made entirely by hand: the handle in ox or mutton bone was heated, bent and smoothed before being coupled to the blade, which in turn had followed a production process divided into forging, grinding and marking with the stamp of the knife maker. A production process that made it possible to create objects that could last a lifetime and resist rust, which had experienced national success at the turn of the two wars, so much so as to push some Tuscan producers to create replicas.
Currently there is no in-depth historical study of this product, but it is estimated that at the beginning of the twentieth century there were about 20 knife makers who worked full time on this product. The Vernantin production process is not codified; some research conducted in the 1980s at local level, however, made it possible to identify the key elements by interviewing some artisans who still practiced the art of knife making, which seem to date back to the 15th century. In the 80s, the municipal administration sought to set up a course for knife makers which however never saw the light. Today in the village there are two people (Mario Vallauri and Giacomo Vallauri), who perpetuate the Vernantin tradition as a hobby.
