Last time I butchered I did 3 roos and all I can say is: wow you learn so much each time and each time goes better! I had bought a new knife but it was junk and ended up having to buy a hatchet. I am having my husband make me a lung scraper after a picture of one I saw online that was connected to an air hose which you then use for a water stream. I looked up the price of many tools and they are SO expensive. I'm going to have to order online if I go that route as the local TSC's don't carry any and neither do any of the other feed stores. I am wanting to make a couple killing cones, anyone have a design? We have a couple welders and other tools as we run a large facility so I think it would be pretty easy to fashion. Where do you get your tools? What have you made yourself?
