ABSTRACT:
A barbecue skewer with a protector/extractor for extracting food from the skewer and preventing injuries and contamination of the skewer. The protector/guard is a generally cylindrical member which is slidably mounted on a shank of the skewer and is selectively movable for a position of covering relationship with a pointed end portion of the shank of the skewer to a position of uncovering relationship with the pointed end portion of the shank of the skewer. In a first embodiment, the protector/extractor is retained in the positions of covering and uncovering relationship by the attraction of a permanent magnet and ferromagnetic members. In a second embodiment the protector/extractor is retained in the positions of covering and uncovering relationship with a leaf spring mounted on the protector/retractor. In a third embodiment the protector/extractor is retained in the positions of covering and uncovering relationship by the engagements of a spring biased ball in the protector/extractor and grooves in a shank of the skewer.
