The inspiration is first drawn from the knife, stylizing up this object and making it as pragmatic possible, hence the “pragma” name. It came out that a blade or cutter teeth will be more than simple triangular shapes made by laser cutting of sheet stainless steel. The entire project is then built around this geometric triangle. The knife handle is constructed in two parts ash, and the triangular portion are assembled directly on the blade bonding. For aesthetic as well as industrial reasons, form and assembly process of the wood pieces are the same for the board. Indeed, one can see the edge of the aluminum plate sandwiched by laths as to the knife handle. This triangulation allows the board to host the knife in all directions, and for the crumbs to be harvested to leave a clean work. The advantage of the symmetry of this board is that it allows us to simply turn the board once the surface is worn to give it a new life.
