Mishnah Kelim 16:8-17:1

Sugya Map

• Issue: Defining Kli (vessel) status through functional integrity vs. physical decay.
• Nafka Mina: Susceptibility to tumah (Kelim). If an object is a "cover" (chafuy) vs. a "receptacle" (beit kibul), it is ritually inert.
• Primary Sources: Mishnah Kelim 16:8-17:1, Rambam Hilchot Kelim 4:1.

Text Snapshot

Mishnah Kelim 16:8: "A wooden vessel that was broken into two parts becomes clean, except for a folding table..."

• Leshon Nuance: The Mishnah differentiates between keli (functional unit) and mere material. Once a vessel loses its structural definition, it ceases to be a keli—unless it is designed for folding or compartmentalization, where the "broken" state is actually the intended operational mode.

Readings

• Rambam (Hilchot Kelim 4:1): Posits that the threshold for tumah is beit kibul (a space capable of holding). If the object's primary function is protection (chafuy) rather than containment, it is clean.
• Tosafot Yom Tov (16:8 s.v. le-chafuy tahor): Notes the fine line between a "case" (tik) and a "covering" (chafuy). A tik (case) that protects a precious item is a keli because the item requires the case for preservation; a mere chafuy (lid/cover) does not "hold" the object in a functional capacity and is thus excluded.

Friction

• Kushya: Why is a tik chalilin (flute case) debated? If it is a receptacle, it should be tamei. If it is a cover, it should be tahor.
• Terutz: The machloket hinges on how the object is inserted. If the design forces insertion from the side, it lacks the "receptacle" intent; it becomes a mere sleeve, effectively a chafuy rather than a keli.

Intertext

• Mishnah Kelim 26:6: Parallels the distinction between a cover of a box (clean) and the box itself (unclean), establishing that the hefetz (object) must be defined by its capacity to "hold."
• SA Orach Chaim 308: The halachic definition of keli here influences the definition of "carrying" on Shabbat.

Psak/Practice

The meta-heuristic is functionalism: an object's halachic status is determined not by its material, but by its telos (purpose). If it does not hold, it is not a keli. In modern application, this is the bedrock for determining the status of disposable packaging vs. permanent storage.

Takeaway

Halacha recognizes that "brokenness" is a state of mind: if the design intentionally accommodates the split (folding table), it remains a vessel; if the split destroys the capacity to hold, it is mere debris.
