they do this to confuse the consumer.....afaik....under blade “steak” is a 7bone chuck roast...btw, the best for making a pot roast but its not steak.(I’d rather have a good pot roast).
I’m just an Engineer. Don’t know much about butchering; so what I do is ask the butcher at my local Costco. You would be surprised how helpful they are, and how much good info they have.
Over the years you learn some life-lessons. One of the lessons I ‘ve learned is that sincerity is appreciated. If you ask a person who makes a livelihood from working as a Butcher, what cuts of meat he would suggest for a particular purpose (grill, soup, roast, etc), 9 out of 10 times they will be flattered to be asked; and will give you their honest opinion. Plus, the next time you are there, they tend to remember you by name. Makes for a pleasant visit that time, and every time thereafter.
