In my head, there is a Knife. The Knife is silver and serrated and wood-handled. It is the Knife Grandma tells Eden to cut the Challah with on Rosh Hashanah, the Knife she’s used since Livi D.’s would-be Bat Mitzvah. It is well loved, like Eden would say, or worn out, like Grandma would, and knows how to handle itself. It is molded to fit my grip perfectly.
