the present invention relates to a pick or plectrum for stringed instruments , particularly acoustic guitars and electric guitars . the pick of the invention includes a body which may have a conventional , generally triangular shape . the body includes a tip which may be used for conventional picking and / or strumming of a stringed instrument . a top edge is disposed opposite the tip and two side edges extend from the top edge and converge to form the tip . extending from one side edge of the pick is a projection which may be used to tap or hammer the strings of the stringed instrument on the fret board to achieve a legato effect . the projection may have an enlarged shape at an outer end or head and may taper toward the body of the pick . typically , this projection extends approximately parallel to at least a portion of the top edge and is spaced inwardly from the top edge . different sized projections and heads may be used for different applications . in use , typically the top edge is gripped while strumming or picking the strings of the instrument while the other side edge is gripped when using the head to tap or hammer the strings . referring now to the drawings , and particularly to fig1 thereof , there is shown a perspective view of one embodiment of the pick 10 of the present invention . pick 10 includes a body 12 which may have a substantially triangular shape and substantially planar top and bottom or surfaces 11 and 13 . body 12 typically has a very thin cross - sectional dimension to provide the flexibility desired for picking or strumming strings of a stringed instruments . body 12 may include two side edges 14 and 16 and an upper edge 18 . edges 14 and 16 typically converge to form tip 22 . as shown in fig1 , tip 22 has a generally rounded configuration , but in other embodiments , tip 22 could have a more sharply defined or pointed configuration . tip 22 is typically used to strum or pick the strings of a stringed instrument . edges 14 , 16 and 18 may be linear or be slightly curved with a large radius of curvature . the embodiment of fig1 discloses edges with a large radius of curvature . projection 20 may extend from edge 14 , as shown in fig1 , although projection 20 could alternatively extend from edge 16 . as shown more clearly in fig2 , projection 20 includes a base 23 and a head 24 at a distal end of base 23 , where head 24 is enlarged with respect to base 23 . base 23 includes sides 26 and 28 on opposite sides of heads 24 . sides 26 and 28 may taper to the respective opposed surfaces 11 and 13 of body 12 . while sides 26 and 28 are shown as being tapered , sides 26 and 28 instead may extend generally parallel to respective surfaces 11 and 13 of body 12 . in one embodiment , projection 20 extends from edge 14 in a direction generally parallel to portion 17 of edge 18 near its juncture with edge 16 . in another embodiment , projection 20 extends at an angle that is approximately 90 degrees with respect to a line 30 that is drawn from tip 22 to portion 17 and that intersects edge 18 at approximately a right angle with respect to portion 17 . it is to be understood , however , that the angle formed between projection 20 and line 30 need not be exactly 90 degrees , but could be between 60 degrees and 120 degrees . in addition , projection 20 need not extend from body 12 in a direction that is exactly parallel to portion 17 of edge 18 , but could extend at an angle with respect to portion 17 which may vary between + 30 or − 30 degrees . projection 20 typically is spaced inwardly from edge 18 , particularly portion 17 of edge 18 . in another embodiment , projection 20 may extend from body 12 at about the location of the junction between edges 14 and 18 . head 24 may have a rounded configuration along its outer surface 21 facing away from body 12 as shown in fig1 . in one embodiment , head 24 has a semi - cylindrical shape . however , in other embodiments , as shown in fig4 - 8 , the outer surface of head 40 or 50 may have a flat or planar configuration . for example , in the embodiment of fig4 , head 40 may have a disc shape with a flat or planar outer surface 41 . in yet another embodiment , as shown in fig6 , head 50 may have a disc shape with a flat or planar outer surface 51 . head 50 may be thinner in cross - sectional thickness than head 40 . heads 40 and 50 may be provided with a greatly enlarged diameter in other embodiments . heads 40 and 50 are particularly suitable for use with instruments having larger strings , such as a bass guitar . as noted above with respect to fig1 - 3 , in one embodiment , head 20 is provided with tapered sides 26 and 28 which extend from the outer surface 21 of head 24 and taper toward respective opposed surfaces 11 and 13 of body 12 . in another embodiment , as shown in fig4 and 5 , head 40 may be provided with two legs 42 and 44 which extend along and generally parallel to respective opposed surfaces 11 and 13 of body 12 . typically , legs 42 and 44 straddle body 12 of the pick . as shown in fig4 and 5 , legs 42 and 44 typically have a rounded outer surface , but could have flattened outer surfaces , or could have any other suitable shape . in the embodiment of fig4 and 5 , legs 42 and 44 are exposed on the outer surface of the pick . in another embodiment , as shown in fig6 - 8 , head 50 includes a single leg 52 . leg 52 extends from the underside of head 50 toward body 12 of pick 10 . leg 52 includes an enlarged upper portion 54 , which tapers to a thinner portion 56 . portion 56 typically is embedded within body 12 such that it is captured between opposed surfaces 11 and 13 . in this manner , no part of portion 56 of leg 52 is exposed or causes enlargement of the thickness of body 12 , providing uniformly smooth and uninterrupted outer surfaces 11 and 13 for body 12 . this configuration may be preferred by some musicians for ease of playing . in yet another embodiment , as shown in fig9 - 11 , head 60 may be provided with a single leg 62 which extends with a substantially uniform thickness from head 60 toward body 12 of pick 10 . the lower portion of leg 62 is embedded within body 12 such that it resides between surfaces 11 and 13 of body 12 . this embodiment again provides smooth , uniform outer surfaces 11 and 13 . it is also noted that head 60 of this embodiment is provided with a generally semi - cylindrical configuration with a rounded upper surface 61 , which extends to generally straight side surfaces 64 which extend generally parallel to stem 62 . it is to be appreciated , however , that head 60 may have any other configuration , such as those shown for heads 40 or 50 . body 12 typically is formed of materials conventionally used for picks for stringed instruments , such as hardened plastic or nylon . the use of such materials allows tip 22 to be used in a conventional fashion to provide the desired strumming or picking effect and to provide the desired sound quality . in some embodiments , surfaces 11 and 13 may be roughened to facilitate grasping . in some embodiments , heads 24 , 40 , 50 and 60 may be formed of a metal , such as anodized aluminum or steel to provide more durability and to provide the desired sound from the stringed instrument . however , heads 24 , 40 , 50 and 60 may be formed of other hardened materials depending on the effect desired . when being used , typically pick 10 of the present invention may be held between the thumb and the forefinger of the hand near top edge 18 such that projection 20 extends inwardly toward the palm of the hand and tip 22 extends downwardly towards the strings . in this fashion , tip 22 may be used to pick or to strum a stringed instrument , such as an electric guitar . when it is desired to use head 24 , pick 10 may be rotated clockwise about an axis of rotation generally perpendicular to surfaces 11 and 13 of body 12 through approximately 90 degrees such that head 24 now faces the guitar strings . typically , although not necessarily , the pick continues to be held between the thumb and forefinger along edge 16 . with the pick in this position , the guitarist may press the head 24 against individual strings on the fret board ( or finger board ), or against multiple strings depending upon the technique desired for hammering and / or tapping . head 24 may be used to provide the style of play called “ finger tapping .” head 24 may replace a finger , and may be used to attack one or more strings with the picking hand , slamming the string onto the fret board ( or finger board ) and pulling off head 24 at a slight angle . this action activates the sound of the string at the fret where it is tapped , and the sound of the same string is open when released . this may be used for the legato technique previously described . if this technique is quickly repeated , it can produce an arpeggio type of sound . this rotation of the pick from a position in which tip 22 faces the guitar strings to a position in which head 24 faces the guitar strings may be accomplished by pushing the middle finger of the hand holding the pick against projection 20 causing rotation of pick 10 . in this way , the guitarist may move the pick easily and quickly from a position in which the guitarist is strumming or picking with tip 22 to a position in which head 24 is being used , without loss of control of the guitar pick . in addition , pick 10 may be used to perform various slide techniques . these techniques may be performed by hitting one or more of the strings of the guitar with head 24 , similar to a tapping technique , and then sliding the head 24 either up or down the neck of the instrument to produce sounds similar to a standard style of a slide guitar . use of pick 10 permits the guitarist to use the picking hand rather than the hand holding the fret board ( or finger board ) to perform the slide technique , a result which is particularly convenient when playing live for an audience . in addition , head 24 may be used to make chromatic rakes , whereby head 24 is used to hit a fret and glide past several frets and back again to generate sounds of chromatic scale progressions . without limiting the generality of the foregoing , the following dimensions are given by way of example and not by way of limitation . typically , the thickness of a body 12 is about the same as a typical medium thickness , plastic guitar pick . the thickness may be about 0 . 029 inch but range from about 0 . 01 to about 0 . 2 inch . the width of head 24 may range from about 0 . 1 to about 0 . 5 inch or more . the diameter of head 40 may range from about 0 . 1 to about 0 . 5 inch , while the diameter of head 50 may range from about 0 . 3 to about 0 . 7 inch . in one embodiment , heads 24 , 40 , 50 and 60 may be made separately from pick body 12 and joined thereto using conventional techniques such as glue , or by heat sealing or welding . alternatively , the pick body 12 and heads 24 , 40 , 50 and 60 may be molded integrally as a unit . this invention is not limited in its application to the details of
