Title: T-3.Triple thick triple tip pick

Description:
This is a continuation in part of Ser. No. 897,343, filed May 18, 1978, now abandoned. 
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS 
     FIG. 1 is a top view of the disclosure, showing the three tip shapes. 
     FIG. 2 is a front view, showing two of the three edge tapers. 
     FIG. 3 is a side view, showing the third remaining taper and edge wall. 
    
    
     Although other plectrum teach the utility of a plurality of picking points, none have dealt, as in this present disclosure, with a selectable-shape-attack-non yield-taper gradient. It was once thought that flexibility was an important attribute of plectrum. In the disclosed design, however, control articulation and string to string tolerances can be greatly increased, facilitating right hand development and accuracy, since complete rigidity, as embodied in this disclosure, eliminates pick recall, flap and imprecision. 
     To further enumerate the specific structure and nature of said pick, reference is directed to FIG. 1 (top view). 
     The distance between points 1a-6; 2a-5; 3a-4a is 30 MM±15% respectively. 
     Tip 1a is rounded with an arc, tangent to extended intersecting edge lines 4a and 5, by a radius of 6 MM±15%. Tip 2a is rounded with an arc tangent to extended intersecting edge lines 4a and 6, by a radius of 3 MM±15%. Tip 3a is rounded with an arc, tangent to extended intersecting edge lines 5 and 6, by a radius of 1.5 MM. 
     In FIG. 2 (front view), taper 1b is formed by the intersection of two arcs, 3 MM±15% apart, i.e. the thickness of the body of said plectrum, each arc having a radius of 1.5 MM±15%. Taper 2b is formed, in the same way, by two intersecting arcs, each having a radius of 3 MM±15%. The distance between dimension 7, that is, the thickness of the body of the pick, is 3 MM±15%. It can be readily noted from 7 i.e., 3 MM±15%, that the design is at least three times the thickness of conventional plectrum, always under one millimeter. This allows for less total pick movement between strings i.e. increases string to string tolerances and secures a firmer grasp of said pick, facilitating better pick control and accuracy. 
     In FIG. 3 (side view), taper 3b is formed by the intersection of two arcs, 3 MM±15% apart, each arc having a radius of 15 MM±15%. Taper 4b is representative of all non-tip edge walls. 
     THE THREE TIP CHARACTERIZATIONS: 
     (A) Sharp tip 3a (FIG. 1) with long taper 3b (FIG. 3), provides a clear, crisp attack with the most articulation. 
     (B) Blunt tip 1a (FIG. 1) with short taper 16 (FIG. 2), provides a smooth harmonic inducing attack, which glides off the strings. 
     (C) Medium tip 2a (FIG. 1) with medium taper 2b (FIG. 2), provides an attack and feel between A and B above. 
     It is centrally important in the design, to use materials which are nonyieldable at the specified dimensions. Materials such as: stone, acrylic, polycarbonate, high molecular plastics and the like, would be ideal since their rigidity at the specified 3 MM±15%, would effect the benefits of increased accuracy and articulation.
