Definitions

• the present invention relates to a cigar cutter device and a method of cutting cigars using such a device.
• the technical sector of the invention is that of the design and manufacture of devices capable of cutting cigars of various sizes and diameters before tasting them, in particular the sector of the design and manufacture of cigar cutters. with scissors.
• the cigar is sliced on one side rather than cut, by bringing the cutting edges of the blades on either side of the circular section of the cigar and pressing these two cutting edges into two diametrically opposite zones . Therefore the cigar undergoes a crushing before being sliced and, depending on its degree of humidity, especially if it is low, such a crushing results in a burst and tearing of its dress.
• These "guillotine" type devices generally consist of two blades or cleavers linked by engagement and movable in translation according to sliding links inside a rigid case comprising a hole for introducing a cigar.
• the blades or cleavers have an oblique or angular cutting line, in particular in the form of a chevron, relative to the direction of movement of the blades inside the case, the blades coming to obscure the orifice of the case during their moving in the slide and cutting the cigar like a guillotine.
• This type of device also has a number of other drawbacks.
• this type of cigar cutter does not allow either, like the devices described above, to obtain a truly regular simultaneous and symmetrical cut of the cigar despite the mounting in engagement of the blades.

• This has the advantage of making the blades attack on the cigar simultaneous and regular by distributing the pressure forces of the blades around the edge of the cigar in an identical and synchronized manner.
• the arrangement and the conformation of the profile of the blades advantageously allow each of the blades to perform exactly 50% of the cutting work, the cigar being cornered by the symmetrical movement of the blades against the attack profile of each of the two blades and crimped by the semi-circular shape of these, allowing a cutting attack at a maximum of points of the circumference and thus preventing any crushing and cutting of the cigar.
• the device according to the present invention comprises at least one plate comprising an orifice symmetrical with respect to said median axis of the device, said orifice being preferably circular and capable of receiving a cigar, said plate being at least secured to the two scissors at their said axis of rotation and disposed against the external face opposite the cutting plane of one of said blades.
