I want to buy this cooking utensil but have no idea what it is called and where i can buy one from. I think it is mainly used on barbeques. Ive tried googling and had no luck. I'll try describing it as best as i can.

It has 2 large rectangular flat metal wire mesh panels which fold onto one another like a clam when you close them. You can place meat in between the wire mesh and clasp the handles together to hold the meat firmly between the 2 meshes. You can then cook the meat over a flame and flip the utensil to cook the other side of the meat.
