I also learned by doing. I have several knives a cutting board and a hand meat grinder. I also debone, I figure I'm already taking the time to cut the meat I might as well go ahead and get rid of the bones. I've used frez. bags for my meat and never had a problem. Some day I would like to get one of those vaccum pack deals. If you're not sure how to do the cuts there are alot of books out there then can help.
