I am a meat eater, I was a vegetarian for five years back in my early 20s, but I tell you for sure if I had to butcher the damn animals to eat them, I'd probably still be a vegetarian. Hunting em? Maybe, but butchering is something I would not do...
Grandpa was into hunting and same as you he'd do the butchering too. I guess once you become a hunter butchering somehow comes naturally. I guess...
It's something that one gets used to; it wasn't long ago when there was little choice in it if one wanted to eat and provide for oneself, and people had much better skills in respect of self reliance. I think it's sad those skills are being lost and I wonder if they'll come back; doubtful I guess.
I'm glad I've got skills like this, it leaves me a solid level of confidence in my own ability.
