Grill fork: Sold with all barbecue sets, it's chiefly used to stab meat, a useless act that only serves to drain the juices. Turn steaks and chops with tongs, not a fork.
Grill wok: This is designed for grilling pieces of vegetables, but you'd get better results grilling them on skewers as kebabs. If you want to stir-fry, stay in the kitchen.
Thermometer fork: The performance of this kind of grill fork, which has a thermometer built in to the tines, is spotty.
