Like i said use a hatchet. Your a grown man and im sure you can put some force behind the hatchet, you should be able to decapitate the rabbit if you put force behind it. And it will be quick for the rrabbit at least. As well its simply saving a step since your going to have to decapitate the thing when you dress it anyway.

But yeah as people said its going to be very very very bloody as soon as you chop that jugular. Always make sure to swing from the back of the neck as it will crush the spine first and it will give you the proper resistance to create the blunt force trauma required to finish the job.

but yeah do it outside in the woods or something and dont wear nice clothes.

btw what are you doing with the skins? dont tell me your just throwing them out....
