The Impressor™ Smooth Pounding attachment has many uses, one of them is cracking crab. Attach the smooth pounding plate to the universal handle. With a simple controlled downward motion the weightiness of The Impressor™ makes easy work of cracking crab without the splattering of crab juices you get swinging a meat mallet. Hold the crab legs on their side when possible and apply enough pressure directly to the crab to form long cracks in the crab legs and bodies. These cracks will let heat and marinades penetrate into the meat of the crab and enable you to get to it very easily.
