A conventional plectrum can be envisioned as comprised of two areas: (a.) the area that comes into contact with the musician's fingers, that is, the area where gripping takes place, and  (b.)  the area that comes into contact with the strings or the body of the instrument to produce musical sounds, which is generally just known as the "tip" of the pick.  Importantly, these two areas are contiguous.  

In sharp contrast, the 6ePick is designed around a modular (and customizable) system, wherein the two general areas are separate entities that are removably attached to one another. The area that comes into contact with the musician's fingers is named the Main Body (MB), and this body is designed to hold two different accessories that come into contact with the strings or body of the instrument: the "Playing Tip" and the "Sound Rail".  These two accessories each have their own subpage in the above Anatomy of the 6ePick menu.

Here our focus is upon the Main Body.  In very general terms it can be thought of as being a  device for facilitating the use of small tools that are ordinarily held solely by some combination of one's fingers: in essence, it is a "tool holder".   So, in the specific context here, the "tools" would be the Playing Tip and the Sound Rail.  (Parenthetically,  other  accessories are envisioned and being designed that also could be removably attached to the MB,  such as  writing and drawing pens, paint brushes, clay scribes, picks and files,  eating utensils, knive blades and so on).

In more descriptive terms, the MB exhibits a very organic shape, with many curves and undulations that give it a unique and distinctive aesthetic. It is an asymmetric structure, characterized by its streamlined and ergonomic shape, being elongated and extending laterally between two ends. It has two opposing sides that are strongly laterally compressed in their middle sections, sharing a common top side and bottom side.

In top view, the sides exhibit a curved, wavy pattern. Both sides feature a complex curved surface, with one major concave depression conjoined with a narrower neck section. A through-hole exists through the shared center of these two concave depressions. In effect, each side of the MB is ergonomically configured to receive the surfaces of the finger pads that come into contact with it.  And,  the through-hole allows direct skin-to-skin contact between the finger pads on the opposite sides, thus creating frictional resistance to minimize pick slippage.  

Additionally, an array of precision-molded raised dots, coined here as "Pad-Pads", is integrally formed on each side of the Main Body.  These micro-protrusions align with finger pads to enhance frictional engagement and reduce slippage during dynamic use. Finally, strategically placed, raised branding lettering exists on both sides in the area around the through-hole, to provide frictional texture between the musician's fingers and the surface of the Main Body.  And, in the case of the lettering on the left side, when using the front playing position, it forms a semi-circular wall that acts as a physical stop to movement of the thumb.

Each side also has a convex protuberance that extends perpendicularly from the bottom center area of its surface. The two protuberances, slightly differing in size and shape, conjoin at their shared medial edges to form an overall shape suggestive of the ventral fins of a fish. This shape is ergonomically designed to function as two conjoined “finger grips,” which, in combination with the other above-described shape attributes of the two sides, ensure that the MB fits snugly, securely, and comfortably in contact with the fingers of the musician during use.  (Recall from The Origin Story of the 6ePick that the inspiration for the finger grips came from the condyle of the white-tailed deer mandible).

Given that both ends of the MB  are equally functional, that is, they both receive Playing Tips, the overall device lacks a front end or a rear end in the traditional sense. So, based on its rough resemblance to a fish, especially as pertains to the finger grips being suggestive of ventral fins, we are using the designation “front” for the portion that looks like the head of a fish, and the designation “rear” for the portion that resembles a tail of a fish. Following that same anatomical analogy, then, one of the lateral faces of the MB is labelled as the “right side” and the other as the “left side”,  with the labels of “top side” and “bottom side” following suite.

The MB has two sockets, located at its opposite ends,  each identically configured to receive the mounting portion of a Playing Tip,  so we distinguish here between a “front socket” and a “rear socket".  Also, the MB has a long narrow "slot" running down the middle of much of its top side, configured to receive the Sound Rail.  (Again, refer to the relevant subpages in the above Anatomy of the 6ePick menu for further details about the Playing Tip and the Sound Rail).

Overall, the MB is ergonomically configured to make it highly graspable and to maximize the contact area between it and the fingers of the musician.    The goal of the design is two fold:  a. to minimize the short-term potential for slippage or loss of the plectrum while playing, and b. to minimize the long-term potential for finger/hand fatigue, strain or injury, since  a musician does not have to grip the MB as tightly as  one grips a conventional pick, in order to keep a secure hold while playing.

A unique feature of  the overall shape of the MB is that it  can be held in two different playing  positions, each using a different combination of fingers and a different  end of the device.   We refer to these as the "Front Playing Position" and the "Rear Playing Position", on the basis of which end and Playing Tip is being employed. These playing positions are described in detail in the above How to Use menu item.

In furtherance of the goal of producing an ergonomic plectrum that closely fits the user's fingers, the Main Body of the 6ePick presently is available in seven standard sizes, Small (S), Small/Medium (SM), Medium (M), Medium/Large (ML), Large (L), Large/Extra Large (LXL), and Extra Large (XL).  

It is envisioned that the Main Body will be manufactured using various plastics, or even metals, with the expectation that this variable will effect the playability of the 6ePick.  Also,  it has the potential to augment the aesthetics of the pick, especially from a customization point of view.  In any case, for the purposes of the testing program all of the Main Bodies are manufactured from the same plastic. 

Figures 1-6 below reveal different views of the Main Body of a Medium 6ePick,  each with arrows pointing to the various relevant  areas that must be identified and labelled, both  for our presentation here, as well as to provide testers with a shared vocabulary for use in feedback communications about the device.
