A handle for a kitchen utensil or the like includes a hand gripping section having a rearward push/pull valley with a varying, substantially elliptical cross-section that forms a floor, a push slope tapering up and forward from the floor, and a pull slope tapering up and back from the floor. The radial cross-sectional area of an end of the pull slope and a radial cross-sectional area of an end of the push slope each are substantially larger than a radial cross-sectional area of the floor. The handle section further includes a ring stop section disposed forward of the push/pull valley with one or more concentric rings extending above a surface of the handle member. The kitchen utensil includes a blade mating section disposed forward of the handle section and configured to receive a blade.

1. A handle (10) comprising: a shaft including a valley (25) arranged and designed to conform generally to at least a portion of a user's closed hand, said shaft characterized by radial cross-sections along its entire length, each radial cross-section having an outer surface defined by an ellipse having a center, wherein a straight longitudinal axis passes through each center of each ellipse, and wherein said radial cross-sections change as a function of length, thereby forming a floor (64), a push slope (62) which slopes up and forward from the floor (64), and a pull slope (60) which slopes downward from an end (27) of the shaft toward said floor (64), wherein a cross-sectional area of an end of the pull slope (60) and a cross-sectional area of an end of the push slope (62) each are substantially larger than a cross-sectional area of the floor (64),a utensil mating section (40) arranged and designed to connect said shaft to a utensil (50); anda ring stop section (30) disposed on said shaft at a location remote from said utensil mating section (40) and forward of said valley (25), said ring stop section (30) including at least one ring (33) having a raised surface above a surface of the shaft and arranged and designed to allow contact with the user's thumb and at least one finger when the user's hand is closed around said valley (25). 2. The handle (10) of claim 1 wherein, the ring stop section (30) includes three equally-spaced rings (33). 3. The handle (10) of claim 1 wherein, the utensil (50) is a spatula for kitchen use. 4. The handle (10) of claim 1 further comprising, a utensil (50) detachably attached to said shaft. 5. A handle (10) for connection to a kitchen utensil (50) comprising: a shaft having a blade mating section (40), and a first gripping section, said first gripping section having a push/pull valley (25) arranged and designed to conform generally to at least a portion of a user's closed hand, said shaft characterized by radial cross-sections along its entire length, each radial cross-section having an outer surface defined by an ellipse having a center, wherein a straight longitudinal axis passes through each center of each ellipse;said valley (25) including a pull section (60) which slopes downward from a rear end (27) of said shaft to a rear valley end, wherein the pull section rear end (27) has a larger radial cross-sectional area than a radial cross sectional area of the pull section rear valley end, and an upward sloping push section (62) having a front valley end and a front end, wherein the front end has a larger radial cross-sectional area than a radial cross sectional area of the front valley end; andsaid shaft having a second gripping section (30) disposed on said shaft at a location remote from said blade mating section (40) and forward of said push/pull valley (25) characterized by at least one raised concentric ring (33) disposed on said second gripping section (30), said at least one raised concentric ring (33) arranged and designed to allow contact with the user's thumb and at least one finger when the user's hand is closed around said valley (25). 6. The handle (10) of claim 5 further comprising, a spatula blade (50) coupled to a forward end of said handle (10), said blade characterized by a thin structure that has horizontal and vertical dimensions and a major axis of each of said cross sectional areas of said shaft is aligned with said vertical dimension of said blade. 7. The handle of claim 5 wherein said blade mating section has a substantially elliptical radial cross section. 8. A handle (10) having a straight longitudinal axis, the handle comprising: an elongated shaft extending longitudinally along the straight longitudinal axis of the handle, the shaft characterized by radial cross-sections along its entire length, each radial cross-section having an outer surface defined by an ellipse having a center, wherein a straight longitudinal axis passes through each center of each ellipse, said shaft having an ergonomic grip and a fixture mating end (40) configured for attachment of fixtures, with the ergonomic grip having a continuously curved rearward concave/convex section defining a push/pull valley (25), shaped to conform generally to at least a portion of a user's closed hand and to allow generation of force by the user with a pushing motion and with a pulling motion;wherein the shaft further has a stop section (30) disposed on said shaft at a location remote from said fixture mating end (40) and forward of said push/pull valley (25), said stop section having a plurality of rings (33) disposed on said shaft, raised above a surface of said shaft, and arranged and designed to contact one or more fingers of a user's hand when the user's hand is closed around said valley (25). 9. The handle of claim 8, wherein, the elongated shaft changes as a function of length along said shaft. 10. The handle of claim 8 wherein, said plurality of rings (33) are concentric and equally spaced. 11. The handle of claim 8 wherein, said plurality of rings are raised from said elongated shaft. 12. The handle of claim 8 wherein, said plurality of rings are created by grooves formed in said elongated shaft.
