Step 1: In a large mixing bowl, combine the softened cream cheese, shredded sharp cheddar cheese, Worcestershire sauce, garlic powder, onion powder, black pepper, and salt. Use an electric mixer to beat on medium speed until the mixture is light, fluffy, and well combined, scraping down the sides of the bowl as needed.
Step 2: Transfer the cheese mixture onto a piece of plastic wrap. Using the plastic wrap as a guide, shape the mixture into a firm, round ball. Wrap tightly in the plastic wrap.
Step 3: Refrigerate the wrapped cheese ball for at least 2 hours, or preferably overnight, to allow the flavors to meld and the ball to firm up.
Step 4: Once chilled, unwrap the cheese ball. On a shallow plate, spread out the finely chopped pecans. Roll the cheese ball gently in the pecans, pressing lightly to ensure the nuts adhere evenly to all sides.
Step 5: Place the coated cheese ball on a serving platter. Let it sit at room temperature for about 15-20 minutes before serving to soften slightly. Serve with an assortment of crackers, pretzels, and fresh vegetable sticks.
