Roughly 2 million kitchen knives are being voluntarily recalled following reports of hand and finger lacerations from the blades breaking, federal authorities announced Wednesday.

The massive recall of Calphalon Contemporary Cutlery specifically targets blades sold between August 2008 and this past December, the Consumer Product Safety Commission said in a press release.

Thirteen models that were sold individually for $25 and in sets for $300 are specifically being recalled. The recalled model numbers are as follows: 1808008, 1808009, 1821332, 1922890, 1922971, 1922976, 1932810, KNR0005C, KNR0007C, KNR10045C, KNR4008C, KNSR002C and KNSR0102C.
