I carried a small hatchet for several years, until another party member showed up with a folding locking saw about 7" long, that he picked up at a hardware store. I went out and bought one, also works for trimming shooting lane from tree stand. Buckmasters sent me one since as a premium for renewing my subscription.
Another member of my party says that it is a waste of time to cut through the bone and just cuts out the anus and pulls it out with intestines.
