Abstract: A toggle assembly is provided for use with a fastener to engage a supportive structure. One or more teeth are positioned adjacent a lower peripheral edge of one or both of the toggle wing members. The teeth are oriented to engage a rearward surface of the supportive structure once the toggle assembly is passed through an opening formed in the supportive structure and the toggle assembly moves into an open position. One alternate embodiment provides inserts that may be selectively disclosed within recesses of the toggle wing members and provides one or more teeth for engagement with a rearward surface of a supportive structure to substantially prevent rotation of the toggle assembly while a fastener is passed therethrough and tightened.

Abstract: A hand-held, battery-operated rotary blade saw useful for cutting plastic clips or straps which secure a face mask to a football helmet. Several configurations, having differing safety shields, are disclosed. The device is an emergency/rescue tool to quickly remove a face mask from a football helmet allowing access to the face of a football player without removal of the helmet with its concomitant risk of cervical injury.
