you really don't need a sharp knive to flesh a yote, there isn't much to take off one. with the pelt on the beam, start at the behind the ears and push down. you will get a think layer of muscle and fat that will come off, keep working it all the way around and keep pushing it down til you get the tail then just push it off,
honestly theres not much fleshing to do to a yote or fox, unlike a deer or coon.
