With three restaurants under his watchful eye, chef Jeremy Sewall finds himself opening a lot of oysters these days – after all, Island Creek Oyster Bar sort of specializes in the briny little bivalves; Eastern Standard is no slouch in the shucking department; and Lineage, with its daily dollar oyster special, goes through plenty in its own right. To make all this shucking go a little more smoothly, Sewall would like a top-of-the-line oyster knife, like the ones made by R. Murphy Knives, located in Ayer, Massachusetts. Choose from an assortment of styles – depending on your oyster of choice – and get cracking.
