Step 1In a large bowl, whisk together the smoked paprika, sweet paprika, cumin, garlic, salt, pepper, lime juice and one-third cup olive oil. Add the shrimp and gently toss to coat. Cover and refrigerate 30 minutes to 1 hour.
Step 2Soak the skewers 30 minutes before grilling, then thread the shrimp, 3 to each skewer.
Step 3Heat a grill or grill pan over medium-high heat. Brush the grill with the remaining 2 tablespoons oil. Grill the shrimp just until cooked through (the shrimp will become firm and turn opaque), 2 to 4 minutes per side, careful not to overcook. Serve hot.
