Martha Stewart Collection Whiteware cake knife and server sets sold at Macy’s have been recalled after reports of lacerations resulting from handles of both products breaking while in use. In at least one instance, a cut from a broken handle required stitches.

The U.S. Consumer Product Safety Commission last week advised anyone who purchased the set to immediately cease using the products and contact Macy’s for a refund. According to the CPSC, lacerations suffered by users occurred after breaks where the blades met textured ceramic handles on both products, which each measured approximately 11 inches. Four such cases were reported to Macy’s.

“In cooperation with the U.S. Consumer Product Safety Commission, Macy's is recalling the Martha Stewart Collection Whiteware cake knife and server sets, announced on Oct. 13,” the company told International Business Times in a statement. “The handles on the knife and server can break during use, posing a laceration hazard.”

The sets were available for purchase at Macy’s locations nationwide, online and at Military Exchanges between January 2014 and July 2017, CPSC said. Customers who contact the respective retailer at which the set was purchased can expect a full refund. The sets were sold at Macy’s for $25 and at Military Exchanges for $15.

Packaging for the products included the UPC 608356963330 and Product ID PRCDCKSRVR. An estimated 18,900 of the sets were sold.

Another product from the Martha Stewart Collection collection was recalled in December of 2015, when the CPSC received seven reports of metal discs that covered the collection’s frying pan rivets popping off and causing minor injuries. Injuries reported during use included bruises, burns and welts, according to a recall notice at the time.
