Description
FIELD OF THE INVENTION
[0001] The present invention is related to cigar smoking implements
and accessories. More particularly, this invention is a cutting
device for opening the head of a cigar in preparation for
smoking.
BACKGROUND
[0002] The head of a cigar is the tip which the smoker places in
his mouth during smoking. Cigars are sold with their heads in a
"closed" state, that is, the binder and wrapper cover the head
completely to retain the compacted filler and provide a neat and
tapered tip. Cigars are occasionally also sold with their feet
closed for the same reason. Additionally, binders and wrappers help
to keep fresh the filler tobacco, so cigars that are sold with
their heads and feet closed tend to remain fresh longer.
[0003] Another reason that cigars are sold with their heads closed
is that cigar smokers generally prefer to open the heads
themselves, according to their smoking preferences and comfort. If
the opening size is larger, more flow will result, which will
result in more flavor, but will also cause the cigar to burn faster
and hotter. A smaller opening will cause the cigar to burn slower
and cooler, but will provide a milder flavor.
[0004] Cutting devices for opening the heads of cigars come in two
main types, slicers and punches. Punches are tubular cutting tools
that create a longitudinal hole into the center of the head. The
diameter of the hole is always the same as the size of the punch,
so punches are available with either a smaller punch diameter,
generally in the 6 MM diameter range, or a larger punch diameter,
generally in the 8 MM diameter range. Slicers, on the other hand,
typically consist of one or two sharp blades that traverse and
slice through the head to remove the head tip and create an opening
that traverses the cigar, normal to the cigar's longitudinal
axis.
[0005] A punch may be used on any cigar regardless of the cigar's
diameter. But since there is no strict standard for cigar
diameters, some cigars may be too fat for use with some slicers,
when the diameter of the cigar cannot fit within the aperture of
the slicer.
[0006] Some smokers prefer smoking a cigar that has been opened by
a punch, while others prefer a cigar that has been opened by a
slicer. Slicers can be more damaging to the cigar head,
particularly as the slicer blades become dull, but many smokers
prefer the feel of a sliced head and the wider opening a slicer
produces. Also, heads can be re-sliced as they become moist and
ratty. Punches, on the other hand, tend to produce a more
well-defined and consistent opening, causing fewer stray tobacco
bits.
[0007] Some smokers will vary the opening type according to the
cigar. Certain cigars are prone to smoke hotter, be stronger, or
have more flavor than others, leading the smoker to prefer a
particular head opening size and style according to the cigar type.
The same smoker may prefer to have a sliced opening in one type of
cigar and a punched opening on another. Or the smoker may prefer to
have a smaller punched opening in one type of cigar and a larger
punched opening on another.
[0008] Since cigar smoking is typically a social activity, it is
common for several smokers to share a single cigar cutting tool.
Should the available tool be a slicer, those smokers who prefer a
punched opening must compromise. Should the available tool be a
punch, those smokers who prefer a sliced opening must
compromise.
[0009] There is therefore the need for a cigar cutting device which
is useable with any cigar, and such is an object of the present
invention.
[0010] There is also the need for such a cigar cutting device which
is capable of cutting any cigar according to the smoker's
preference, and such is an object of the present invention.
[0011] There is also the need for such a cigar cutting device which
is simple and convenient to use, and such is an object of the
present invention.
[0012] There is also the need for such a cigar cutting device which
is compactable into a safe storage condition wherein its blades are
protected from damage and the smoker is protected from injury, and
such is an object of the present invention.
[0013] There is also the need for such a cigar cutting device which
has a slicing blade that locks automatically into its storage
position at the completion of a cut, and such is an object of the
present invention.
[0014] And there is the need for such a cigar cutting device in
which all blades may be either biased or locked into their storage
positions, and such is an object of the present invention.
[0015] Further objects and advantages of the present invention will
become apparent in view of the following disclosure of an exemplary
embodiment thereof.
SUMMARY OF THE INVENTION
[0016] The invention is best summarized as a cigar cutting tool
having a housing defining an aperture sized to receive a cigar
head, a first cutting element having a sharpened linear edge
movable relative to and across the aperture, a second cutting
element having a sharpened tubular edge extendable from the housing
and having a cutting diameter, and a third cutting element having a
sharpened tubular edge extendable from the housing and having a
cutting diameter smaller than the cutting diameter of the second
cutting element. The first cutting element may be movable between
an open position exposing the aperture and a closed position fully
covering the aperture and protecting the sharpened linear edge
within the housing. The tool may be used for selectively causing
one of a plurality of openings in a cigar head.
[0017] The cigar cutting device as preferably embodied has a
plurality of slicing and punching means to allow one or more
smokers to customize the opening of each cigar to be smoked. The
invention overcomes the deficiencies of the prior art by providing
a cigar cutting device which is useable with any cigar, which is
capable of cutting any cigar according to each smoker's preference,
which is simple and convenient to use, which is compactable into a
safe storage position wherein its blades are protected from damage
and the smoker is protected from injury, which has a slicing blade
that locks automatically into its storage position at the
completion of a cut, and in which all blades may be either biased
or locked into their storage positions.
[0018] Further features and aspects of the invention are disclosed
with more specificity in the Detailed Description and Drawings of
an exemplary embodiment provided herein.

DETAILED DESCRIPTION
[0026] Reference is now made to FIGS. 1 through 6, where there is
shown an exemplary cigar cutting tool 100 according to just one of
the infinite number of possible embodiments within the scope of the
invention, and a cigar 200 to be opened thereby.
[0027] Cigar cutting tool 100 has a housing 102 defining an
aperture 104, preferably 20 MM in diameter, to receive cigar head
202. First cutting element 106 has a sharpened linear edge 108
movable relative to and across the aperture. Second cutting element
112 has a sharpened tubular edge 114 extendable from the housing
and preferably has an 8 MM cutting diameter. Third cutting element
116 has a sharpened tubular edge 118 extendable from the housing
and preferably has a 6MM cutting diameter.
[0028] First cutting element 106 is movable between an open
position exposing aperture 104, and a closed position fully
covering the aperture and protecting the sharpened linear edge
within the housing. FIG. 2 shows the first element almost in its
fully open position and FIG. 1 shows the element in its closed
position. First cutting element 106 is biased towards its open
position by compression spring 122. Releasable pawl 124 engages
indentation 126 to retain the first cutting element in its closed
position, as shown in FIG. 1, against the bias of spring 122. Pawl
124 automatically engages indentation 126 to retain the first
cutting element as the first cutting element is moved to its closed
position by the bias of pawl spring 128, best seen in FIG. 4.
[0029] Release button 132 is rigidly connected to pawl 124 such
that inward force on the button moves pawl 124 outwardly against
the bias of spring 128 and out of engagement with indentation 126,
as seen in FIG. 4, thereby allowing compression spring 122 to force
first cutting element 106 automatically to its open position, as
shown in FIGS. 2, 4 and 6.
[0030] Second cutting element 112 and third cutting element 116 are
each movable between an extended position wherein the respective
second or third cutting element extends from the housing, shown for
element 116 in FIG. 4, and a retracted position wherein the
respective second or third cutting element is retracted into the
housing and the respective sharpened tubular edge is protected
within the housing, shown for element 112 in FIG. 4. In their
extended positions, the second and third elements preferably extend
approximately 8 MM from the housing.
[0031] The second and third cutting elements each comprise a hollow
interior chamber 134 for receiving the punched-out plug 204 from
the cigar head 202. An ejector 136 is disposed within and movable
relative to each of the hollow interior chambers and adapted to
force the plug from the respective chamber as the respective second
or third cutting element is moved from its extended position to its
retracted position, as appreciated by comparing FIGS. 3 and 4. The
second and third cutting elements are each biased towards its
retracted position, as seen in FIGS. 1 and 3, by an associated one
of compression springs 138.
[0032] Housing 102 has a pair of openings 142 each adjacent to and
associated with one of the second and third cutting elements, each
opening has a longitudinal slot portion 144 and a transverse slot
portion 146. Lugs 148 are each fixed to and movable with the
respective second or third cutting element, each lug movably
received within an associated one of the openings.
[0033] The lugs serve as both actuators for causing movement of the
associated element and as retaining means for cooperating with the
associated openings to hold the associated elements in their
extended positions. Longitudinal outward movement of each lug
within the associated slot's longitudinal slot portion 144 causes
the associated one of the second or third cutting elements to move
from its retracted position to its extended position, and
transverse outward movement of each lug within the associated
slot's transverse slot portion 146 causes the associated one of the
second or third cutting elements to be retained in its extended
position, as seen in FIG. 2.
[0034] Second cutting element 112 and third cutting element 116 are
coaxially disposed, which, as can be appreciated by viewing FIGS. 3
and 4, provide for the sharing of numerous common features and
symmetry of design. Such symmetry is found to provide improved
balance and feel while using the tool, and renders the tool equally
functional for both left-handed and right-handed smokers.
[0035] To use the tool, a smoker first selects a desired one of a
sliced opening, an 8 MM diameter punched opening, or a 6MM diameter
punched opening for cigar head 202, and accordingly follows either
process a), b) or c); [0036] a) For a sliced opening, the smoker
moves the first cutting element 106 to its open position, inserts
cigar head 202 into aperture 104; and moves the first cutting
element to its closed position to thereby slice an opening through
the cigar head. [0037] b) For an 8 MM diameter punched opening, the
smoker extends the second cutting element 112 from housing 102,
secures it in its extended position, and pushes the second cutting
element longitudinally into the center of cigar head 202 to thereby
punch an 8 MM diameter opening into the cigar head. [0038] c) For a
6 MM diameter punched opening, the smoker extends the third cutting
element 116 from the housing, secures it in its extended position;
and pushes the third cutting element longitudinally into the center
of cigar head 202 to thereby punch an 8 MM diameter opening into
the cigar head.
[0039] Upon completion of process a), the first cutting element 106
is forced back into housing 102, and pawl 124 automatically engages
indentation 126 to retain the first cutting element in its closed
position. Upon completion of process b), the lug 148 associated
with second cutting element 112 is forced transversely back towards
longitudinal slot potion 144 and the cutting element is forced back
into its retracted position by the force of its associated spring
138, whereupon the punched out plug 204 is forced from hollow
chamber 134 by ejector 136. Upon completion of process c), the lug
148 associated with third cutting element 116 is forced
transversely back towards longitudinal slot potion 144 and the
cutting element is forced back into its retracted position by the
force of its associated spring 138, whereupon the punched out plug
204 is forced from hollow chamber 134 by ejector 136.
[0040] In summary, the invention may be embodied as a cigar cutting
tool having a housing defining an aperture sized to receive a cigar
head, a first cutting element having a sharpened linear edge
movable relative to and across the aperture, a second cutting
element having a sharpened tubular edge extendable from the housing
and having a cutting diameter, and a third cutting element having a
sharpened tubular edge extendable from the housing and having a
cutting diameter smaller than the cutting diameter of the second
cutting element.
[0041] The first cutting element may be movable between an open
position exposing the aperture and a closed position fully covering
the aperture and protecting the sharpened linear edge within the
housing, and may be biased towards the open position.
[0042] The cutting tool may further have means for retaining the
first cutting element in its closed position. The means for
retaining the first cutting element may automatically retain the
first cutting element in the closed position as it is moved
thereto. The means for retaining may be a releasable pawl and the
first cutting element may be automatically retained in its closed
position as it is moved thereto by the releasable pawl. Release of
the pawl may enable the first cutting element to automatically move
to its open position.
[0043] The second and third cutting elements may each be movable
between an extended position wherein the respective second or third
cutting element extends from the housing and a retracted position
wherein the respective second or third cutting element is retracted
into the housing and the respective sharpened tubular edge is
protected within the housing. The second and third cutting elements
may each have a hollow interior chamber for receiving the
punched-out plug from the cigar head, and the cutting tool may
further have ejectors disposed within and movable relative to each
of the hollow interior chambers and adapted to force the plug from
the respective chamber as the respective second or third cutting
element is moved from its extended position to its retracted
position.
[0044] The second and third cutting elements may each be biased
towards its retracted position. The cutting tool may further have
means for retaining the second and third cutting elements in their
respective extended positions The housing may have a pair of
openings each adjacent to and associated with one of the second and
third cutting elements, each opening having a longitudinal slot
portion and a transverse slot portion. The means for retaining the
second and third cutting elements may include a lug fixed to and
movable with each of the respective second or third cutting
element, each lug movably received within an associated one of the
openings. Longitudinal outward movement of each lug within the
associated slot's longitudinal slot portion may cause the
associated one of the second or third cutting elements to move from
its retracted position to its extended position, and transverse
outward movement of each lug within the associated slot's
transverse slot portion may cause the associated one of the second
or third cutting elements to be retained in its extended position.
The second and third cutting elements may be coaxially
disposed.
[0045] The invention may also be embodied as a method of
selectively causing one of a plurality of openings in a cigar head
using a single cutting tool having a housing defining an aperture
sized to receive the cigar head, a first cutting element having a
sharpened linear edge movable relative to and across the aperture,
a second cutting element having a sharpened tubular edge extendable
from the housing and having a cutting diameter, and a third cutting
element having a sharpened tubular edge extendable from the housing
and having a cutting diameter smaller than the cutting diameter of
the second cutting element, where the first cutting element is
movable between an open position exposing the aperture and a closed
position fully covering the aperture and protecting the sharpened
linear edge within the housing.
[0046] The method may include selecting a desired one of a sliced
opening, a large diameter punched opening, or a small diameter
punched opening for the cigar head, and following either process
a), b) or c) with the single cutting tool, where process a) is for
a sliced opening and includes; [0047] moving the first cutting
element to its open position, [0048] inserting the cigar head into
the aperture; and [0049] moving the first cutting element to its
closed position to thereby slice an opening through the cigar head,
where process b) is for a large diameter punched opening and
includes; [0050] extending the second cutting element from the
housing; and [0051] pushing the second cutting element
longitudinally into the center of the cigar head to thereby punch a
large diameter opening into the cigar head; and where process c) is
for a small diameter punched opening and includes; [0052] extending
the third cutting element from the housing; and [0053] pushing the
third cutting element longitudinally into the center of the cigar
head to thereby punch a small diameter opening into the cigar
head;
[0054] While the invention has been shown and described with
reference to a specific exemplary embodiment, it should be
understood by those skilled in the art that various changes in form
and detail may be made without departing from the spirit and scope
of the invention, and that the invention should therefore only be
limited according to the following claims, including all equivalent
interpretation to which they are entitled.
