Sharpening a stick and sticking a hot dog on it to cook over an outdoor fire is an old fashioned way to cook outdoors. Get yourself a Firefork and that dog will never have to touch a stick. The spring metal of the Firefork will hold onto the stick. The protective polycarbonate storage cover will even keep it clean while travelling. If keeping things sanitary in the outdoors is a requirement for you, maybe you should look into one.
