and a handle comprising a handle body attached to the elongated shank, wherein the handle body comprises a proximal end, a distal end, a proximal portion, a middle portion, and a distal portion; wherein the middle portion is disposed between the proximal portion and the distal portion, wherein the distal portion is disposed between the distal end and the middle portion, wherein the proximal portion is disposed between the middle portion and the proximal end, wherein the distal portion comprises circumferentially-distributed distal portion faceted recesses, wherein each of the distal portion faceted recesses is defined by a distal portion first triangular facet and a distal portion second triangular facet, wherein each distal portion first triangular facet extends from a proximal end of the distal portion to a distal end of the distal portion, and wherein each distal portion second triangular facet extends from the proximal end of the distal portion to the distal end of the distal portion. ### Claim 4 A manual driver comprising: an elongated shank extending along a shank axis; and a handle comprising a handle body attached to the elongated shank, wherein the handle body comprises a proximal end, a distal end, a proximal portion, a middle portion, and a distal portion; wherein the middle portion is disposed between the proximal portion and the distal portion, wherein the distal portion is disposed between the distal end and the middle portion, wherein the proximal portion is disposed between the middle portion and the proximal end, wherein the distal portion comprises circumferentially-distributed distal portion faceted recesses, and wherein the distal portion faceted recesses comprise six of the distal portion faceted recesses. ### Claim 5 A manual driver comprising: an elongated shank extending along a shank axis; and a handle comprising a handle body attached to the elongated shank, wherein the handle body comprises a proximal end, a distal end, a proximal portion, a middle portion, and a distal portion; wherein the middle portion is disposed between the proximal portion and the distal portion, wherein the distal portion is disposed between the distal end and the middle portion, wherein the proximal portion is disposed between the middle portion and the proximal end, wherein the distal portion comprises circumferentially-distributed distal portion faceted recesses, wherein the handle has a handle length from the proximal end to the distal end, and wherein each of the distal portion faceted recesses extends between 37 to 47 percent of the handle length. ### Claim 6 (depends on 3) The manual driver of claim 3, wherein a cross-section area of the handle through the distal end of the distal portion is less than a cross-sectional area of the handle through the proximal end of the distal portion. ### Claim 7 A manual driver comprising: an elongated shank extending along a shank axis; and a handle comprising a handle body attached to the elongated shank, wherein the handle body comprises a proximal end, a distal end, a proximal portion, a middle portion, and a distal portion; wherein the middle portion is disposed between the proximal portion and the distal portion, wherein the distal portion is disposed between the distal end and the middle portion, wherein the proximal portion is disposed between the middle portion and the proximal end, wherein the proximal portion comprises circumferentially-distributed proximal portion faceted recesses, wherein each of the proximal portion faceted recesses is defined by a proximal portion first triangular facet and a proximal portion second triangular facet, wherein each proximal portion first triangular facet extends from a proximal end of the proximal portion to a distal end of the proximal portion, and wherein each proximal portion second triangular facet extends from the proximal end of the proximal portion to the distal end of the proximal portion. ### Claim 8 A manual driver comprising: an elongated shank extending along a shank axis; and a handle comprising a handle body attached to the elongated shank, wherein the handle body comprises a proximal end, a distal end, a proximal portion, a middle portion, and a distal portion; wherein the middle portion is disposed between the proximal portion and the distal portion, wherein the distal portion is disposed between the distal end and the middle portion, wherein the proximal portion is disposed between the middle portion and the proximal end, wherein the proximal portion comprises circumferentially-distributed proximal portion faceted recesses, and wherein the proximal portion faceted recesses comprise six of the proximal portion faceted recesses. ### Claim 9 A manual driver comprising: an elongated shank extending along a shank axis; and a handle comprising a handle body attached to the elongated shank, wherein the handle body comprises a proximal end, a distal end, a proximal portion, a middle portion, and a distal portion; wherein the middle portion is disposed between the proximal portion and the distal portion, wherein the distal portion is disposed between the distal end and the middle portion, wherein the proximal portion is disposed between the middle portion and the proximal end, wherein the proximal portion comprises circumferentially-distributed proximal portion faceted recesses, wherein the handle has a handle length from the proximal end to the distal end, and wherein each of the proximal portion faceted recesses extends between 19 to 29 percent of the handle length. ### Claim 10 (depends on 9) The manual driver of claim 9, wherein a cross-section area of the handle through the proximal end of the proximal portion is less than a cross-sectional area of the handle through the distal end of the proximal portion. ### Claim 11 (depends on 1) The manual driver of claim 1, wherein: the handle further comprises an information ring and an end cap; the end cap comprises an end cap elongated shaft and a flanged portion; the information ring defines an information ring central aperture; the handle body defines an end cap receptacle; and the end cap elongated shaft extends through the information ring central aperture and into the end cap receptacle. ### Claim 12 (depends on 7) The manual driver of claim 7, wherein: the distal portion comprises circumferentially-distributed distal portion faceted recesses; each of the distal portion faceted recesses is defined by a distal portion first triangular facet and a distal portion second triangular facet; each distal portion first triangular facet extends from a proximal end of the distal portion to a distal end of the distal portion;
