Flat Irons: The 2nd most tender steak on a beef next to filets. 🥩 The MKC x Bearded Butchers Boning Knife is Dropping THIS THURSDAY at 7PM MST / 9PM EST on MKC's website! @montanaknifecompany | @thebeardedbutchers
At least at the shop I worked at, that was done because of how difficult the proper trim is relative to the value of the steak. Cut through like that, we called them top blade steaks, though we did charge $3 less per pound compared to actual flat iron cut. These guys have beautiful cuts, though the amount of excess trim they produce would have gotten me taken off the meat block. Different priorities between actual butchers and chain stores.
What he's doing here will still result in tons of gristle in each steak. This is good technique for a showcase, but not the best for eating. If you wanna do it right, it takes a little while longer than this.
I worked at a chain store in the south, and we all called them flat irons, too. We didn't like putting them out because of shrink, but they were always available on request...might be the same at your store.
