Place the Worcestershire sauce, tamari, lemon juice, honey, garlic and black pepper in a large bowl and whisk to combine. Add the steak on top and toss with the marinade to combine. Set in the fridge for at least 1 hour, or up to 24 hours, to marinate.
When ready to cook, preheat an outdoor gas grill to 450˚F. Place the steak on the grill and cook for about 5 to 6 minutes on each side. If you have an instant read thermometer, 130°F to 140˚F will be medium rare and 150°F will be medium well. Keep in mind that the temperature will continue to rise about 5 degrees after you remove from heat and the steaks rest.
When cooked to your liking, remove from the grill and place on a rimmed platter to collect the juices. Cover and let rest for at least 10 minutes. Slice thinly across the grain and serve.
