Bakeware, Tableware, Drinkware and Cookware Design ButterOnce Corn Butterer by Joseph McMahon Fresh corn on the cob is always a staple at any summer barbecue, but getting butter onto your perfectly grilled corn cob without butter sliding off is nearly impossible. The knife features a curved stainless steel blade that wraps around the ear of corn, perfectly placing the butter into the grooves of the cob. Butter stays on the corn and doesn’t slip off onto plate. This allows much less effort on the user's part while spreading and more even butter application. The beveled side edge allows you to slice off a pat of butter to control how much you wish to apply onto the corn.
