Arukh HaShulchan, Orach Chaim 314:4-12

Sugya Map

• Issue: The boundary between Melachah (prohibited creative work) and Umanut (professional craft) regarding the prohibition of Tofair (sewing) on Shabbat.
• Nafka Mina: Whether "temporary" fastening (e.g., a pin or knot) constitutes Tofair if the intent is not a permanent davar ha-mitkayem.
• Primary Sources: Shabbat 75a; Mishnah Shabbat 7:2; Shulchan Aruch, Orach Chaim 340:1.

Text Snapshot

• Arukh HaShulchan, Orach Chaim 314:4: "כל שתופר שני דברים... חייב משום תופר."
• Leshon Nuance: The Arukh HaShulchan emphasizes that Tofair is not merely the act of piercing, but the act of chibbur (joining) that establishes a functional unit. Note the shift from the mechanical act to the teleological result.

Readings

• Rambam (Hilchot Shabbat 10:11): Defines the threshold of Tofair via the requirement of davar ha-mitkayem. The chiddush is that Tofair is a relational prohibition—it requires a state of permanence to trigger the melachah.
• Arukh HaShulchan (314:6): He argues that Tofair is forbidden even where the stitch is not "permanent" in the sense of leather-working, provided it serves a functional, conventional purpose. He expands the definition of Tofair beyond the Mishkan model of durability.

Friction

• Kushya: If Tofair is defined by davar ha-mitkayem, how can the Arukh HaShulchan permit certain temporary pins while prohibiting others?
• Terutz: The distinction lies in the ma'aseh (act) vs. the tza'ar (intent). If the fastening is inherently ephemeral, it lacks the gmar melachah (completion of work) required for the issur.

Intertext

• Shulchan Aruch, Orach Chaim 340:1: The formalization of the prohibition of tying and sewing.
• Responsa Chatam Sofer, Orach Chaim 92: Discusses the nuance of "temporary" joins as a shvut vs. issur de-oraita.

Psak/Practice

The Arukh HaShulchan facilitates a lenient approach toward modern fasteners (like paperclips or temporary garment clips) so long as they do not mimic the tziyur of a permanent stitch. Avoid "stapling" (metal fasteners that require force to remove), as that approaches the davar ha-mitkayem threshold.

Takeaway

Tofair is defined not by the needle, but by the "permanence" of the union. If the join is conceptually temporary, the melachah remains dormant.
