US Patent 10300592 Ergonometric utility handle

An ergonometric utility handle having a main body portion having an end that fits in a cupped palm and concavities emanating from the end that lengthwise substantially conformingly receive palm sides of a thumb and at least one finger. The concavities are widely dish shaped or bound and defined by gently sloped surfaces disposed in laterally outwardly spaced relation to the utility object or a mounting element therefor and against which the thumb and finger or fingers can be positioned and pressed to control and exert useful mechanical advantage. Additional features include a cantilever element against which a finger can be pressed to enhance control and mechanical advantage, an ability to remove and reorient a utility object, such as to reverse the diagonal cut of a brush tip, and an ability to attach an extension in one or more ways.
