In a small bowl, combine the olive oil, salt, coriander, paprika, black pepper, onion powder, oregano and garlic. Rub the steaks on both sides with the mixture and let sit at room temperature for 30 minutes.
Prepare a grill for medium-high heat. Grill the steaks until the internal temperature registers 125 degrees F on an instant-read thermometer for medium rare, 8 to 10 minutes per side. Remove the steaks from the grill, top each with 1 to 2 tablespoons of the Herb Butter and let rest for 5 to 10 minutes.
Cut the meat from each side of the bone and slice across the grain into strips. Arrange around the bone and top with more Herb Butter for serving.
In a large bowl, blend the butter, chives, parsley, Worcestershire, salt and pepper until completely combined. Use immediately or wrap into a cylinder in plastic wrap and refrigerate for up to a month.
