Description

FIELD OF THE INVENTION

The present invention relates to cigar cutters, and in particular to a cigar cutter which has two blades at two sides. The blades can move inwards to a fixed position and to cut a cigar and moreover, the two blades is movable outwards by an easy operation with slightly force applied thereto so that a cigar can be inserted into a hole in the cigar cutter for being cut.

BACKGROUND OF THE INVENTION

Many cigar cutters exist in which one or two blades push through a cigar. Such cutters can be appropriately called guillotine or double-guillotine cutters. These types of cutters suffer from the deficiency that they can crush, squash, or otherwise deform the cigar as they cut it. They can also tear the wrapper leaf or the endcap of the cigar as the blades are forced through the cigar.
In one prior art a cigar cutter, the cigar cuter comprises a frame with a slot and a hole therethrough, said frame having two sides which are parallel to each other, said frame being teardrop shaped, which slot has a rectangular cross section, and which hole is perpendicular to the slot and is sized to accommodate a cigar tip; and two blades, each blade with a hinge end and a cutter end, said cutter end having two edges, the first of which said edges is sharp and the second of which is dull, said blades hingeably coupled with each other and said frame and operably mounted so that said blades slide through the slot in said frame and effectuate movement of first edges of said cutter ends of said blades across each other scissors-like, said blades crossing at the hole in said frame.
Furthermore, in another type of cigar cutter exists in which a part of the cigar cutter can be pivotally displaced with respect to another part of the cigar cutter. In the course of this pivoting movement, the cutter's blades are subjected to a rotational movement corresponding to the pivoting movement and concurrently to a translational movement, thus progressively effecting the cutting of the cigar. In the alternative, the cigar cutter includes a lever that is turnable. By pivoting the lever, the cutter's blades are moved circularly in a hypocycloidal path. Both embodiments produce a peripheral cutting action at the same time that the blades penetrate into the cigar.
In view of the art, a need exists for a cigar cutter in which the application of a squeezing force causes the cutter's blades to cut a cigar in a manner intended to avoid substantial deformation and tearing of the cigar.

SUMMARY OF THE INVENTION

Accordingly, the primary object of the present invention is to provide a cigar cutter, which has two blades at two sides. The blades can move inwards to a fixed position and to cut a cigar and moreover, the two blades is movable outwards by an easy operation with slightly force applied thereto so that a cigar can be inserted into a hole in the cigar cutter for being cut.
To achieve above objects, the present invention provides a cigar cutter mainly formed by a bottom sheet, a left blade, a right blade and an upper sheet. The four sheets are locked by a stud, while the left and right blade are movable with respective to the bottom sheet. The centers of these sheets have holes which are aligned. When a cigar passes through the hole, the two blades can move inwards to cut the cigar. A skilled design mechanism is formed in the four sheets so that as the two blades can be received within the two blades in a storage state. When it is desired to insert a cigar into the holes of the sheets, the two blades can be compressed inwards, and than the blades will resilient outwards by resilient forces of springs.
