Those were the days...
My FFA class came out to my farm one day to observe castrations. Sharp knife, unwilling bull calves, and some hungry dogs...
You made me loose it! LOL!
Uncle John at the farm used to take us to the barn to help him. Yeah, pretty graphic but...Life.
Then there are the reindeer herders in Scandinavia. Reportedly the SAMI, think Native American, Eskimo, well the knives long ago were important so the herders, usually the women, did it with their teeth.
I kid you not. A gal acquaintance still goes with her dad and has told me about it.
