Arukh HaShulchan, Orach Chaim 234:7-235:8

This is a fascinating on-ramp into a complex area of hilchot Shabbat, specifically the interplay between melacha and tashmishei melacha, and the subtle distinctions that inform psak. The Arukh HaShulchan, as is his wont, navigates these waters with meticulousness.

• Issue: The permissibility of using an article as a tool for its primary function on Shabbat, even if that function is indirectly related to melacha or if the article itself is muktzeh due to its primary function. Specifically, the Arukh HaShulchan grapples with the use of a keli shemelachto le'issur (utensil whose primary use is forbidden on Shabbat) for a reshut (permissible) purpose on Shabbat.

Text Snapshot

The Arukh HaShulchan, Orach Chaim 234:7, begins by discussing the general rule of keli shemelachto le'issur:

"הלכה כוותיה דאביי, דאמרינן בפרק זה בורר [שבת קד, ב] דלא אסרינן אלא כלי שמלאכתו לאיסור, אבל כלי שמלאכתו להיתר, ואפילו אם הוא משמש לפעמים לאיסור, מותר להשתמש בו לצורך היתר."

Nuance: The Arukh HaShulchan emphasizes the halacha follows R' Abaye's opinion. The crucial distinction is between a utensil whose מלאכה is for issur (i.e., its primary designed function is a forbidden melacha), and one whose מלאכה is for heter (whose primary designed function is permissible). The former is forbidden even for a permissible use, while the latter is permissible even if it's sometimes used for a forbidden purpose. This highlights that the inherent design and primary function of the utensil are key.

Later, in 234:10, he addresses shechiyata (slaughtering):

"ואם באו תרנגולין או יונים וקרבו עצמן להשחיטן, וכן אם באו תרנגולין או יונים ובקשו לעמוד לפניו להשחיטן, מותר להחזיק בידו סכין של שחיטה, מפני שאין בו משום כלי שמלאכתו לאיסור, אלא מלאכתו מצוה. והוא הדין לכל דבר שמלאכתו מצוה, כגון סכין של מילה, או כלי של תרומה."

Nuance: The Arukh HaShulchan explicitly states that a knife for shechiyata is not considered keli shemelachto le'issur because its melacha is a mitzva. This is a critical expansion of the principle. The melacha itself, if it's a mitzva, elevates the utensil. He then broadens this to include a circumcision knife (sakin shel milah) and vessels for terumah. This suggests that the category of keli shemelachto le'issur is specifically for melachot that are prohibited by the Torah for their own sake.

Readings

Rif (Rabbi Yitzchak Alfasi) on Shabbat 104b

The Rif, in his condensation of the Talmudic discussion on keli shemelachto le'issur, lays the groundwork for the entire sugya. He quotes the Gemara:

"אמר רב יוסף: כלים שהיו לצרכי בעל הבית, ואף על פי שמלאכתן לאיסור, מותר ליתן בהן את האוכל. ואמר רב יוסף: אמר קרא 'כל כלי בית יוסף' [שמואל א, כ"א, ה], יכול מה ששימש לבעל הבית, אף על פי שמלאכתו לאיסור, ליתן בו את האוכל. אמר רב פפא: לא, 'כל כלי בית יוסף' – אלא כלי שמלאכתו להיתר, ואף על פי ששימש לאיסור. תנן התם: כלי שמלאכתו להיתר, ואף על פי ששימש לאיסור, מותר. כלי שמלאכתו לאיסור, ואף על פי ששימש להיתר, אסור."¹

The Rif's understanding, as presented here, is that the primary distinction lies in the intended or designed function of the utensil. If its melacha is for heter, it remains permissible for heter uses, even if it has been used for issur. Conversely, if its melacha is for issur, it remains forbidden even for heter uses. This is the foundational principle that the Arukh HaShulchan elaborates upon. The Rif's primary contribution is his concise distillation of the Gemara's debate, highlighting the differing interpretations of "כלי בית יוסף" and settling on the dominant view: the melacha itself is the determining factor.

Rambam (Maimonides), Hilchot Shabbat, Chapter 21, Halacha 10

The Rambam codifies this principle with his characteristic precision:

"כלי שמלאכתו לאיסור, כגון קופיטא וגוביינא, וכן סכין של קצבים, ושל ציידין, ושל גרדין – אסורין לכל צרכיהן, בין לצרכן שהן מלאכתן, ובין לשאר צרכי היתר. ואף על פי שאין במלאכתן איסור, אלא שהן משמשים לדבר שאסור. אבל כלי שמלאכתו להיתר, כגון סכין של אומנין, ושל שחיטה, ושל מילה – מותרים לכל צרכיהן, בין לצרכן שהן מלאכתן, ובין לשאר צרכי היתר."²

The Rambam's chiddush here is in his categorization and explicit examples. He lists kofita (a tool for pounding), gubayna (a file), and knives of butchers, hunters, and weavers as keli shemelachto le'issur. He clarifies that even if the act itself isn't a prohibited melacha (eino be'issur), if the utensil is used for something forbidden, it becomes forbidden. This contrasts with utensils whose melacha is l'heter, such as knives for artisans, slaughtering, or circumcision. The Rambam's clarity on the nature of melacha – whether it's inherently prohibited or merely associated with a prohibited act – is key. His inclusion of sakin shel shechita and sakin shel milah as l'heter directly informs the Arukh HaShulchan's point in 234:10. The Rambam’s emphasis is on the inherent purpose and nature of the utensil's creation and primary function.

Friction

The Arukh HaShulchan's assertion in 234:10 that a knife for shechiyata is not keli shemelachto le'issur because its melacha is a mitzva, and by extension, other mitzva related implements, presents a subtle friction with the foundational principle of keli shemelachto le'issur. The standard understanding, as seen in the Rif and Rambam, is that keli shemelachto le'issur refers to utensils whose primary function is one of the thirty-nine melachot of Shabbat, or something closely related that is prohibited.

Kushya: If the melacha of a knife is to cut, and cutting is a melacha de'oraita (e.g., coreh - tearing, or socher) when done on Shabbat, how can a knife specifically designed for cutting (melachto) not be keli shemelachto le'issur when used for cutting? The act of shechiyata itself is a mitzva, but the tool's function is cutting, which can be a forbidden melacha. Why isn't the knife categorized by its potential forbidden function, rather than the specific context of its mitzva use?

Terutz 1 (Implicit in Arukh HaShulchan's wording): The Arukh HaShulchan seems to be drawing a distinction based on the intent of the Torah in prohibiting certain implements. The prohibition of keli shemelachto le'issur is fundamentally to prevent the performance of a forbidden melacha or the enhancement of such a melacha. When a utensil's inherent purpose is tied to a mitzva, the Torah's intent is not to prohibit that utensil from fulfilling its mitzva role. The melacha of shechiyata is not merely "cutting"; it's a specific, commanded act of service. Therefore, the knife is not seen as a tool for a forbidden melacha, but for a commanded act. This is akin to how certain actions permissible in weekdays are prohibited on Shabbat; the prohibition is tied to the day and its sanctity, not solely to the physical act itself. The melacha of the knife is therefore melachat mitzva, which is a distinct category from melacha de'issur.

Terutz 2 (Deeper Lomdus): One could argue that the Rambam's definition of keli shemelachto le'issur as "אסורין לכל צרכיהן, בין לצרכן שהן מלאכתן, ובין לשאר צרכי היתר"³ implies that the prohibition is tied to the inherent nature of the melacha itself. If the melacha is one of the prohibited thirty-nine, then the utensil is muktzeh. However, shechiyata, while involving cutting, is not one of the thirty-nine melachot in the same way as coreh or socher in the context of tailoring or construction. Instead, shechiyata is a category of ritual slaughter that is a mitzva. The Arukh HaShulchan is extending the principle of melacha de'mitzva to the utensil itself. The melacha of the knife is shechiyata, which is a mitzva, not a forbidden melacha. Therefore, it is not keli shemelachto le'issur. This is a subtle but significant distinction: the type of melacha determines the utensil's status. Melacha de'issur makes the utensil muktzeh, while melacha de'mitzva does not.

Intertext

Yerushalmi, Shabbat, Chapter 9, Halacha 3

The Yerushalmi offers a parallel discussion that reinforces the distinction between the object and its context:

"רבי יונה אמר: כלים שהיו צריכין לבעל הבית, אף על פי שהן מלאכתן לאיסור, מותר להשתמש בהן לדבר היתר. רבי אלעזר אמר: מותר ליתן בהן את האוכל. רבי יוחנן אמר: אם היו משמשים לאיסור, אסורין. והלכה כרבי יוחנן."⁴

The Yerushalmi's debate, as reflected here, touches upon the same core issue: whether the prohibition of keli shemelachto le'issur is absolute or conditional. While the Yerushalmi ultimately rules like Rabbi Yochanan (who seems to lean towards the stricter view, similar to R' Papa in the Bavli, making it forbidden even for heter uses if its primary purpose is issur), the underlying discussion highlights the tension. The Arukh HaShulchan, by stating "הלכה כוותיה דאביי,"⁵ is aligning with the more lenient opinion in the Bavli, which permits using keli shemelachto le'issur for heter purposes if its primary function is heter. The Yerushalmi’s discussion, even in its stricter ruling, shows the underlying logic of distinguishing between the utensil's inherent nature and its application. The Arukh HaShulchan's decision to follow the Bavli's halacha in this instance, and his expansion of this leniency to mitzva objects, demonstrates a consistent approach prioritizing the intended or sanctified use.

Shulchan Aruch, Orach Chaim 308:10 (Regarding Tefilin)

The Shulchan Aruch itself, in the laws of Rosh Chodesh and Chol HaMoed, addresses the permissibility of performing mitzvos with objects that might otherwise be problematic. While not directly about keli shemelachto le'issur, it offers a meta-principle:

"אם יש לו תפילין של רשות, ואינו יכול להתפלל בהן, ורוצה להתפלל בתפילין של מצוה, מותר."⁶

This passage, while brief, implicitly acknowledges that mitzva objects can sometimes override or be treated differently than their secular counterparts. The concept of tefilin shel mitzva versus tefilin shel reshut highlights that the purpose and halachic designation of an object can alter its status. The Arukh HaShulchan's approach to sakin shel shechita as melacha de'mitzva aligns with this idea that the mitzva context elevates the object. It suggests a hierarchy where the sanctity of a mitzva can influence how a utensil associated with it is viewed, even if the physical action it performs could, in another context, be forbidden.

Psak/Practice

The Arukh HaShulchan's analysis has direct implications for psak. The ruling that a knife for shechita is permissible for shechita on Shabbat, and by extension, other mitzva implements, is a practical application of the principle that melacha de'mitzva does not render an object keli shemelachto le'issur.

This means that if one needs to perform a mitzva on Shabbat that requires a specific tool, and that tool's primary function is the performance of that mitzva, it is permissible to use it. For example, a knife for shechita is permitted for shechita. A sakin shel milah is permitted for brit milah. This is not merely about using a permissible tool for a permissible act; it's about the inherent status of the tool itself being defined by its mitzva function.

The meta-heuristic here is to always consider the primary intended purpose of the utensil. If that purpose is a mitzva (like shechita or milah), the utensil is not muktzeh due to being keli shemelachto le'issur. If its primary purpose is a forbidden melacha, it remains muktzeh even for permissible uses. This nuanced understanding prevents over-application of muktzeh prohibitions when the mitzva context is paramount.

Takeaway

The halachic status of a utensil hinges not just on the physical act it performs, but on the Torah's intended purpose for that act. Melacha de'mitzva blesses the tool, setting it apart from implements designed for forbidden labor.
