Jason Yang, butcher at Fleishers Craft Butchery, breaks down half a cow into all the cuts you would see at your local butcher shop. There are four sections Yang moves through:

1. ROUND: bottom round roast beef, eye round roast beef, sirloin tip steak, london broil steak, shank (osso buco)
2. LOIN: sirloin steak, tenderloin steak, flank steak, filet mignon, New York strip steak
3. RIB: skirt steak, ribeye steak
4. CHUCK: brisket, ranch steak, denver steak, chuck steak or roast, flat iron steak

A useful skill to have is to know how to tie a butcher's knot. As I show you more complex butchery techniques and preparation, you will need to use a butcher's knot to tie meat together to ensure even cooking.

What is the perfect steak? Well to be honest it is all down to personal preference.
However, the way you cook it can change everything. A perfectly tender steak can be transformed into something that resembles shoe leather, all dried out and chewy in minutes.

Butcher Justin Williams shows Bon Appetit how to butcher an entire lamb and explains every cut of meat. There are six sections of the lamb that yield edible cuts: the neck, the shoulder, the rib, the loin, the kidneys, and the leg. From those sections, the butcher can offer boneless shoulder roast, spare ribs, rack of lamb, lamb noisette, lamb breast, leg of lamb, stir fry, stew, lamb chops and merguez sausage.

Yuji Haraguchi is a butcher and owner of the fish market Osakana. In this episode of Handcrafted, Haraguchi shows Bon Appétit how to butcher a whole tuna and explains every cut of fish you would see at sushi restaurants. To do this, Haraguchi uses five knives: the Yanagi, which is used for slicing sashimi, the Mioroshi Deba filleting knife with narrow thin blade, the Deba single-edged knife used for breaking down the whole fish, the Gyuto versatile multipurpose chef's knife, and the Yo-Deba. He breaks down the tuna into back loin, belly loin, pelvic fins, bones, and collars. From there, the cuts are broken down into saku blocks and sashimi like toro, chu-toro, sinews, sankaku, akami, tuna tartare, and aburi.
