We have been using a filet knife to cut the carotid (long knife is good here). We pull the heads and use an 8" kitchen knife to remove feet, slit the neck (to pull out the crop and trachea), and to cut above the vent. The wife uses a butter knife with a bent tip as a lung scraper (my hands are too clumsy to get lungs out). I use a 6" skinning knife to cut up the bird and a cleaver to remove the necks and split the back. We tried to match what we had laying around with what we needed it for.
It's more efficient to use different knives at each station and to have extras sharp and ready.
