As Rosh Hashanah approaches, many Jews observe a lesser-known custom with profound significance: buying a new knife. This Chassidic tradition symbolizes asking God for a plentiful livelihood. But what’s behind this practice?

In Jewish mysticism, every detail holds meaning. The word “chatach” (חתך), meaning “cut,” is associated with the angel in charge of livelihood. Interestingly, the final letters of Psalm 145:16, “You open up Your hand,” spell “chatach.” Additionally, the next word, “u’masbe’a” (“and satisfy [the desire of every living being]”), has a numerical value matching “chatach” (428). This connection makes purchasing a new, sharp knife a spiritually propitious act for livelihood.

The correlation between parnassah (livelihood) and knives is also found in Rosh Hashanah prayers. We declare, “hachotech chayim l’chol chai” (“He cuts life to every living person”). Reb Yitzchok Eizik of Zidichoiv explains that the last letter of “poseach es yodecha” (“open your hands to receive His blessings of sustenance”) spells “chotach” (ches, tof, chof), meaning “to cut.”

This tradition has been passed down through Chassidic leaders. The Lubliner Rebbe would gift his close disciples with new knives on Rosh Hashanah. Whether buying new or sharpening an old one, this practice aligns physical preparations with spiritual aspirations for the new year.

As we welcome Rosh Hashanah, may this custom inspire reflection on our connection to God’s abundance. May He inscribe you, your family, and all Jewish people for a year abundant in livelihood and blessings.

Important Reminder:
Before using your new knife, don’t forget to immerse it in the Mikveh (ritual bath), as is customary for all new silverware. If forgotten, immersion cannot be performed on Shabbat or holidays, and the knife cannot be used until properly immersed.
