While the classic, unadorned beechwood skewer is still very popular, more modern versions are available. Stainless steel and bamboo are good alternatives. Skewers can range between 10 and 50 cm in length. The latter are sold in sets of 4 (stainless steel skewers being the most expensive) or in packs of 100 for wood and bamboo skewers. Currently, more and more skewers are available with a prong that stops food from rotating, and skewers that prevent heat transfer. The undeniable innovation is the arrival of flexible stainless steel skewers, a design that offers even cooking over any type of grill or barbecue. There are other types of skewers, known as toothpicks (cocktail sticks), for use with hors d’oeuvres and cocktails. These allow for appetizers to be picked up easily. These also come in stainless steel, bamboo, or plastic, and are oven decorated on one end.
