Extendable implements include a handle and functional end that extends or retracts therefrom through a release. The handle and functional end are configured to provide user-implement synergy or ergonomics that account for typical hand grips and extension functionality together. Synergistic or ergonomic features can include any combination of positioning the release to avoid a strong grip on an extended implement, configuring the release to require definite voluntary actuation, extension and retraction of the functional end with a single hand not contacting the functional end, a deep handle molded to a forceful open grip, a functional end dimensioned to prevent deflection or breaking during extended typical use, a functional end dimensioned and a release configured to provide reliable extension, retraction, and/or locking of functional end, etc.

1. An implement comprising: a handle shaped to accommodate a human hand grip with a thumb on top of the handle and fingers extending partially around the handle;a functional end connected to the handle and extendable and retractable relative to the handle, wherein the functional end is positioned in a plane of the top of the handle so as to face a user during operation; anda release positioned on the handle at a position toward the functional end beyond the fingers and facing away from the top to completely avoid the thumb and the fingers of the grip, wherein the release and the functional end are correspondingly configured to permit extension and retraction of the functional end when the release is actuated. 2. The implement of claim 1, wherein, the functional end is extendable in a length direction,the handle extends in a depth direction greater than in a width direction,the depth direction is perpendicular to the length direction,the depth direction is directed from the top to a bottom of the handle, andthe width direction is perpendicular to both the depth and the length directions and is directed from one side to another side of the handle. 3. The implement of claim 2, wherein the release is positioned on one of the sides of the handle. 4. The implement of claim 3, wherein the handle includes a bottom surface shaped with several concavities to match contours of the fingers, and wherein the release is positioned on the one of the sides at a lengthwise position beyond the several concavities so as to completely avoid the grip. 5. The implement of claim 3, wherein the release is positioned on a left side of the handle and the handle is shaped to accommodate a grip of a right hand. 6. The implement of claim 1, wherein the release is positioned to be reachable and actuated by only the thumb departing from the grip. 7. The implement of claim 1, wherein the release is a single latch extending from only one of the sides of the handle, and wherein the release actuates by compression toward a side of the handle perpendicular to the top where the thumb grips. 8. The implement of claim 1, wherein the functional end includes a shaft that is captured by the handle and the release. 9. The implement of claim 8, wherein the release is a latch having a button and a variable-diameter bushing, wherein the shaft includes an internal track that selectively engages with the bushing, and wherein the internal track and bushing prevent the shaft from extending beyond the button. 10. The implement of claim 9, wherein the track extends completely through the shaft in a width direction and has a variable depth such that the shaft is moveable relative to the latch only when the latch is actuated, and wherein the latch is biased to remain unactuated when not contacted by the thumb. 11. The implement of claim 1, wherein the functional end includes a spatula facing a same direction as the top of the handle. 12. The implement of claim 1, wherein the handle is formed by a plurality of removably joined casings. 13. The implement of claim 12, wherein the casings, when joined, form the handle and define a slot into which a shaft of the functional end can pass to provide extension and retraction of the functional end. 14. The implement of claim 13, wherein the slot and the release are configured to allow the functional end to extend or retract under gravity alone. 15. An implement comprising: a handle having a top that faces a user, a bottom opposite the top, and a first side and an opposite second side both between and perpendicular to the bottom and the top, wherein, the top and the bottom are positioned apart a first distance in a depth direction,the first and the second sides are positioned apart a second distance in a width direction, andthe first distance is larger than the second distance sufficient for an average human hand gripping the handle to surround the bottom and the first side and to position a thumb of the gripping hand on the top of the handle;a functional end extendable and retractable relative to the handle; anda release on the opposite second side of the handle, wherein the release and the functional end are correspondingly configured to permit extension of the functional end when actuated. 16. The implement of claim 15, wherein the functional end cannot extend completely outside the handle. 17. The implement of claim 16, wherein the functional end includes a shaft that is captured by the handle and moveable in only a length direction within the handle when the release is actuated. 18. An implement comprising: a handle;a functional end including a shaft that passes into the handle; anda release, wherein the functional end is not extendable and not retractable in the handle when the release is not actuated, wherein the functional end is extendable and retractable in the handle and not to outside the handle when the release is actuated, and wherein the functional end is extendable or retractable under gravity alone when the release is actuated and the functional end is pointed with gravity in a direction of extension or retraction. 19. The implement of claim 18, wherein the release is positioned on the handle at a location completely separate from any area that would be contacted by a human hand gripping the handle while using the functional end, and wherein the release can be actuated only by the hand departing from the grip. 20. An implement comprising: a handle shaped to accommodate a human hand grip with a thumb on top of the handle and fingers extending partially around the handle;a functional end connected to the handle and extendable and retractable relative to the handle in a length direction, wherein, the functional end includes a shaft that is captured by the handle,the shaft extends in a depth direction greater than in a width direction,the depth direction is perpendicular to the length direction and is directed from the top to a bottom of the handle, andthe width direction is perpendicular to both the depth and the length directions and is directed from one side to another side of the handle; anda release positioned on the handle at a position toward the functional end beyond the fingers and facing away from the top to completely avoid the thumb and the fingers of the grip, wherein the release further captures the shaft to permit extension and retraction of the functional end when the release is actuated.
