Arukh HaShulchan, Orach Chaim 307:12-17

Sugya Map

• Issue: The scope of Muktzeh Machamat Chessaron Kis (items set aside due to their monetary value) and the status of "professional" tools.
• Nafka Mina: Can one use a tailor’s shears for non-tailoring tasks (e.g., cutting food) without violating Muktzeh?
• Primary Sources: Shabbat 123b; Shulchan Aruch OC 308:1; Arukh HaShulchan 307:12-17.

Text Snapshot

• Arukh HaShulchan 307:17: "וכל זה הוא דוקא כשהכלי מיוחד למלאכה שאסור לעשותה בשבת... אבל אם מיוחד למלאכה שמותר לעשותה בשבת – מותר לטלטלו..."
• Leshon Nuance: R’ Epstein shifts from the nature of the object to the intent of the owner (yichud). The dikduk here suggests that Muktzeh is functional, not ontological.

Readings

• Magen Avraham (308:1): Limits Muktzeh to items rarely used for anything else. If a "valuable" item is used occasionally for a permitted task, the Muktzeh status dissolves.
• Arukh HaShulchan (loc. cit.): His chiddush is the democratization of the tool. He argues that since modern household tools are multi-purpose, the "professional" distinction is fading, effectively narrowing the scope of Machamat Chessaron Kis.

Friction

• Kushya: If the Gemara (Shabbat 123b) explicitly restricts tailor's shears, how can R’ Epstein broaden the leniency?
• Terutz: R’ Epstein distinguishes between Kli Umanuto (a tool whose primary use is forbidden) and a Kli whose value is strictly tied to a singular, professional trade. If a tool is common enough to be used for permitted tasks, it ceases to be "set aside" in the mind of the owner.

Intertext

• SA Orach Chaim 308:1: The baseline definition of Kli Umanuto.
• Mishnah Berurah 308:2: Takes a more stringent approach, fearing the "professional" label remains even if the tool is occasionally used for minor tasks.

Psak/Practice

• Psak: Follow the Arukh HaShulchan’s functionalist approach: if an object is frequently used for permitted tasks (opening packages, light food prep), it loses its Muktzeh status, regardless of its original "professional" intent.

Takeaway

• Muktzeh is a psychological boundary, not a physical one; once a tool serves the home, it sheds the status of the shop.
