How do you carve a leg of lamb?

Remove the atch bone and split the leg from the atch bone to the shin, removing the cartilage at the knee, then remove the bottom bone at the ankle. Once the bones are removed you will be left with a flat piece of meat, on each side of the meat there will be a fat piece of meat, split the meat at that point and fold back the fat bit. One butterflied lamb leg...easy peasy
