A cutter for a whole piece of food comprising cutting means, a movable structure suitable for positioning the whole piece of food and a stopper arranged in such a way as to support the whole piece of food when positioned on said movable structure wherein: - the movable structure comprises a confining area which is suitable for securing the whole piece of food with: i. a base, ii. an opening through which a section of the whole piece of food, when positioned in the said base, is exposed to the said cutting means and iii. confining means of the whole piece of food, being configured to move along a cutting plane arranged obliquely to the gravitational axis and consisting of a closed circuit including: i. a first movement line including a point at which the movable structure is adjacent to the cutting means and ii. a second movement line including a point at which the movable structure is at a pre-set distance further from the cutting means, - the stopper being: i. spaced apart by a predefined portion of the said cutting means and ii. arranged substantially perpendicular to the cutting plane and along the movement line to the cutting means, such that when the whole piece of food is positioned in the confining area of the movable structure through the said opening, it abuts against the stopper; - the cutting means being arranged: i. substantially perpendicular to the said cutting plane, intersecting it, and ii. in such a way that when the whole piece of food is positioned in the said base of the movable structure against the stopper and the movable structure is moved along the first movement line, the whole piece of food is cut to the extent of the said pre-set portion. - the movable structure comprises a confining area which is suitable for securing the whole piece of food with: i. a base, ii. an opening through which a section of the whole piece of food, when positioned in the said base, is exposed to the said cutting means and iii. confining means of the whole piece of food, being configured to move along a cutting plane arranged obliquely to the gravitational axis and consisting of a closed circuit including: i. a first movement line including a point at which the movable structure is adjacent to the cutting means and ii. a second movement line including a point at which the movable structure is at a pre-set distance further from the cutting means, i. a base, ii. an opening through which a section of the whole piece of food, when positioned in the said base, is exposed to the said cutting means and iii. confining means of the whole piece of food, i. a first movement line including a point at which the movable structure is adjacent to the cutting means and ii. a second movement line including a point at which the movable structure is at a pre-set distance further from the cutting means, - the stopper being: i. spaced apart by a predefined portion of the said cutting means and ii. arranged substantially perpendicular to the cutting plane and along the movement line to the cutting means, such that when the whole piece of food is positioned in the confining area of the movable structure through the said opening, it abuts against the stopper; i. spaced apart by a predefined portion of the said cutting means and ii. arranged substantially perpendicular to the cutting plane and along the movement line to the cutting means, - the cutting means being arranged: i. substantially perpendicular to the said cutting plane, intersecting it, and ii. in such a way that when the whole piece of food is positioned in the said base of the movable structure against the stopper and the movable structure is moved along the first movement line, the whole piece of food is cut to the extent of the said pre-set portion. i. substantially perpendicular to the said cutting plane, intersecting it, and ii. in such a way that when the whole piece of food is positioned in the said base of the movable structure against the stopper and the movable structure is moved along the first movement line, the whole piece of food is cut to the extent of the said pre-set portion.
