I do the corotid artery slit. Some advice: don't start the process if you aren't feeling up to your best. Being a bit tired can cause lack of focus. Only use a very sharp knife and one you're used to using.
I was on bird #6, and I have done hundreds, I was tired and getting stiff, using a new knife, and just wanted to get done. This is what happened when I did the slit, it had healed quite a bit by this pic, but took a while.
