The cue stick also includes a first joint disposed at a second end thereof and a second portion having a second joint adapted to mate with the first joint disposed at a first end of the second portion and a butt disposed at a second end thereof. The first and second portions comprise an elongated conic section when joined and have the tenon disposed at a narrower end of the conic section than the butt. The cue stick includes a raised straight edge having a length less than a distance separating the first joint from the tenon and attachment means for securing the raised straight edge to the first portion on an outside surface thereof and substantially parallel to a longitudinal axis thereof. ## Claims ### Claim 1 A cue stick adapted for table sports, said cue comprising: an elongated conic frustum including a butt disposed at a first end and a tenon disposed at a second end and further including a shaft disposed therebetween, said shaft comprising a tapered cylindrical conic section adapted to fit human hands; a raised straight edge separate from said shaft; and attachment means coupling the entire length of said raised straight edge to said shaft along a longitudinal axis thereof. ### Claim 2 (depends on 1) The cue stick adapted for table sports as claimed in claim 1, wherein there is further included: a ferrule attached to said tenon and enclosing said tenon; and a tip secured to a distal end of said ferrule, said tip adapted to striking a cue ball. ### Claim 3 (depends on 1) The cue stick adapted for table sports as claimed in claim 1, wherein: said raised straight edge includes a lower portion of generally rectangular cross-section; and said shaft includes a longitudinal dado groove adapted to accommodate said lower portion of said raised straight edge. ### Claim 4 (depends on 3) The cue stick adapted for table sports as claimed in claim 3, wherein said attachment means comprises glue. ### Claim 5 (depends on 3) The cue stick adapted for table sports as claimed in claim 3, wherein said attachment means further includes: a multiplicity of grooves disposed at substantially right angles to said dado groove of said shaft; and a similar multiplicity of circlips, each of said multiplicity of circlips disposed in one of said multiplicity of grooves and adapted to firmly engage said lower portion of said raised straight edge. ### Claim 6 (depends on 1) The cue stick adapted for table sports as claimed in claim 1, wherein: said shaft comprises wood; and said raised straight edge comprises wood. ### Claim 7 (depends on 1) The cue stick adapted for table sports as claimed in claim 1, further comprising: a female dovetail groove extending longitudinally along said shaft from a first position near said tenon to a second position, said first and second positions being separated by a distance comparable to a length of said raised straight edge; and wherein said raised straight edge includes a lower portion comprising a male dovetail adapted to fit said female dovetail groove of said shaft. ### Claim 8 (depends on 1) The cue stick adapted for table sports as claimed in claim 1, wherein said raised straight edge further includes a lower portion having a quasi-cylindrical concave shape adapted to receive a portion of said elongated conic frustum extending from a first position near said tenon to a second position more remote from said tenon. ### Claim 9 (depends on 8) The cue stick adapted for table sports as claimed in claim 8, wherein said attachment means includes glue disposed between said lower portion having a quasi-cylindrical concave shape and said portion of said elongated conic frustum. ### Claim 10 (depends on 1) The cue stick adapted for table sports as claimed in claim 1, wherein said elongated conic frustum comprises: a joint disposed between said butt and said tenon, said joint detachably dividing first and second portions of said elongated conic frustum and enabling said first and second portions to be detachably coupled together or separated; and wherein said raised straight edge extends from a first position proximal to said tenon to a second position proximal to said joint. ### Claim 11 (depends on 1) The cue stick adapted for table sports as claimed in claim 1, wherein said raised straight edge includes an outer profile substantially triangular in cross-section. ### Claim 12 (depends on 1) The cue stick adapted for table sports as claimed in claim 1, wherein said raised straight edge includes an outer profile substantially rectangular in cross-section. ### Claim 13 (depends on 12) The cue stick adapted for table sports as claimed in claim 12, wherein said raised straight edge includes a rectangular outer profile having bevelled edges. ### Claim 14 (depends on 1) The cue stick adapted for table sports as claimed in claim 1, wherein said raised straight edge includes an outer profile substantially rounded in cross-section. ### Claim 15 A jointed cue stick adapted for table sports, said jointed cue stick comprising: a first portion having a tenon disposed at a first end thereof and a first joint disposed at a second end thereof; a second-portion having a second joint adapted to mate with said first joint disposed at a first end of said second portion and a butt disposed at a second end thereof, said first portion and said second portion comprising an elongated conic section when joined and having said tenon disposed at a narrower end of said conic section than said butt; a rib separate from said shaft and having a length less than a distance separating said first joint from said tenon; and attachment means for securing the entire length of said rib to said first portion on an outside surface thereof and substantially parallel to a longitudinal axis thereof. ### Claim 16 (depends on 15) The jointed cue stick adapted for table sports as claimed in claim 15, wherein there is further included: a ferrule attached to said tenon and enclosing said tenon; and a tip secured to a distal end of said ferrule, said tip adapted to striking a cue ball. ### Claim 17 (depends on 16) The jointed cue stick adapted for table sports as claimed in claim 16, wherein said attachment means further comprises: a female dovetail groove extending longitudinally along said shaft from a first position near said tenon to a second position near said first joint, said first and second positions being separated by a distance comparable to a length of said rib; and wherein said rib includes a lower portion comprising a male dovetail adapted to fit said female dovetail groove of said shaft. ### Claim 18 (depends on 17) The jointed cue stick adapted for table sports as claimed in claim 17, wherein said rib includes an outer profile including bevelled edges. ### Claim 19 (depends on 15) The jointed cue stick adapted for table sports as claimed in claim 15, wherein said attachment means comprises glue. ### Claim 20 (depends on 15) The cue stick adapted for table sports as claimed in claim 15, wherein said attachment means further includes: a multiplicity of grooves disposed at substantially right angles to said dado groove of said shaft; and a similar multiplicity of circlips, each of said multiplicity of circlips disposed in one of said multiplicity of grooves and adapted to firmly engage said lower portion of said rib.
