It depends! Bamboo Skewers are best for steak kabobs because they don't conduct heat so the meat won't get over cooked. Bamboo skewers should be soaked in water to prevent burning. I like to start soaking them when I start marinating the meat. Flat Metal Skewers are sturdier and can be reused. Be sure to get the FLAT ones otherwise your food will spin around on the skewer and be difficult to flip and cook evenly.
