In some embodiments, a protective apparatus for rotary control knobs may comprise a cover adapted fit over a rotary control knob; a knob cavity internal to the cover adapted to provide space for the rotary control knob to rotate about; and an access aperture located on the surface of cover member and adapted to provide limited user access to the rotary control knob. The cover member may be configured to encase or surround a control knob. The apparatus may further comprise a plate which may be integrally formed or molded to the cover and which contains a control shaft aperture adapted to receive the control shaft of a rotary control assembly. Once a control shaft is inserted through the control shaft aperture, a fastener may be secured to the control shaft over the plate, thereby securing the apparatus to the control shaft.

A cookware handle includes a grip comprising a first side, a second side, a pocket between the first side and the second side, a first aperture in the first side, and a second aperture in the second side. The cookware handle also includes a shaft comprising a proximal end configured to be coupled to cookware, a distal portion positioned in the pocket, and a third aperture aligned with the first aperture and the second aperture. The cookware handle also includes a plug including a ribbed thumb grip aligned with a surface of the first side of the grip. The plug retains the grip on the shaft by filling the first aperture, the second aperture, and the third aperture.

A grip for a cookware handle includes a first side, a second side, a pocket between the first side and the second side, a first aperture in the first side, a second aperture in the second side, and a plug comprising a thumb grip. The plug is configured to retain the grip on a shaft received in the pocket by extending through the first aperture, the shaft, and the second aperture.
