Siman 96 — A Sharp Food Cut with a Knife (Davar Charif)
דין מאכל חריף שנחתך בסכין של בשר
A sharp food (דבר חריף — radish, beet, garlic, onion, horseradish…) cut with a meat knife: the sharpness "extracts" and diffuses the absorbed taste; נטילת מקום, קליפה, גרידה or הדחה depending on intensity, and the מחלוקת on "all forbidden" (כולו אסור)

1. The axiom: the דבר חריף extracts and diffuses the knife's taste
The starting point:
Siman 96 no longer deals with a cooked mixture, but with a sharp food (דבר חריף) cut cold with a meat knife. Normally the taste absorbed in a clean blade would be faint (נ״ט בר נ״ט); but through its sharpness (חורפיה) together with the pressure of the blade (אגב דוחקא דסכינא), the sharp food extracts the absorbed taste and diffuses it like substance (ממש). That is why a radish (צנון) cut with a meat knife becomes forbidden with milk — until one removes the cut spot (נטילת מקום) or a non-Jew tastes it and finds no meat taste in it (seif 1).
| Case | Ordinary food (not sharp) | דבר חריף (sharp) |
|---|
| Clean meat knife, cold cutting | Faint נ״ט בר נ״ט → permitted | Extracts + diffuses the taste → forbidden with milk |
| The engine of the diffusion | — | חורפיה + דוחקא דסכינא |
| The remedy | None (already permitted) | נטילת מקום, קליפה, גרידה or הדחה by intensity |
💡 The marker: this siman no longer speaks of "60 against a drop" as the main framework, but of charif + removal at the cut spot. The golden rule: the sharper and moister the food, the more the blade extracts, and the deeper the removal must be — from a simple rinse (הדחה) up to the thickness of a finger (נטילת מקום).
2. The 3 reflex questions
■ WHICH FOOD? (charif or not) — is it a דבר חריף (radish צנון, beet סילקא, garlic שומין, onion בצלים, leek כרישין, horseradish קריי״ן/תמכא, sour fruits, salted fish)? If yes → it extracts the knife's taste (seif 1-2). If not (apple, turnip, bread…) → no concern (seif 4-5).
↓ we look at the knife
■ WHICH KNIFE? (ben yomo / wiped) — a meat knife that is ben yomo or unwiped (אינו מקונח) → forbidden; יש אומרים: even non-ben-yomo but wiped. A non-Jew's knife → likewise. The ruling depends on the state of the blade (seif 1).
↓ we look at the removal
■ HOW MUCH TO REMOVE? (נטילה / קליפה / גרידה / הדחה) — by intensity: נטילת מקום (thickness of a finger) for the radish; גרידה (scraping) for the squash; הדחה (rinsing) for the turnip. Or: taste it with no meat taste → simple הדחה (seif 1, 5).
⚖ Without removal or tasting → cooked in the milk (seif 1)
If one neither removed נטילת מקום nor tasted, and already cooked the radish in milk → one needs 60 against what the knife touched (and one assesses against the whole blade, excluding the handle / קתא, since one does not know where it touched — Rash״al). And if one cut very fine (דק דק) → the cut is everywhere, hence 60 against the whole radish.
3. The master grid: the graded ladder of removal
An absolute must to memorize. Basis: Mehaber seifim 1-5, read with the Rama, the Taz (s.k. 1, 3, 14) and the Shach.
| Food | Intensity / nature | Remedy (cut spot) |
|---|
| Radish (צנון), beet (סילקא = תרדין) |
Very charif |
🔴 נטילת מקום — the thickness of a finger (כעובי אצבע) |
| Garlic, onion, leek, horseradish, sour fruits, salted fish |
charif (seif 2) |
🔴 Same law as the radish → נטילת מקום |
| Squash / cucumber (קישואים) |
Less charif, moist |
🟡 גרידה alone (scraping, less than קליפה) |
| Turnip (לפת) |
Different taste |
🟢 Even גרידה unnecessary → simple הדחה |
| Any sharp food tasted with no meat taste |
Verified by tasting |
🟢 הדחה suffices |
| Cut דק דק (very fine) then cooked in milk |
Cut everywhere |
🔴 60 against the whole radish |
| Lechatchila per Rashba/Ran/Rama |
The sharpness diffuses everywhere |
🔴 The whole radish forbidden (כולו אסור) |
| Bedieved (after the fact) |
— |
🟡 One forbids only כדי נטילה |
📌 Key reading: first ask which food and which knife; then place yourself on the graded ladder — נטילה > קליפה > גרידה > הדחה. And do not forget the second ladder, that of "how much is forbidden": דק דק → 60 against everything; lechatchila (Rashba/Rama) → כולו אסור; but bedieved → only נטילה.
4. The 5 golden rules
- The דבר חריף extracts and diffuses. Through חורפיה + דוחקא דסכינא, the sharp food draws the taste out of the blade and spreads it like substance (Taz s.k. 3).
- נטילת מקום = the thickness of a finger. Radish / beet cut with a meat knife ben yomo or unwiped → one removes כעובי אצבע, or a non-Jew tastes it (Mehaber seif 1).
- The removal ladder follows the intensity. נטילה (radish) > קליפה > גרידה (squash) > הדחה (turnip); tasting with no meat taste → הדחה (Mehaber seif 1, 5; Taz s.k. 14).
- דק דק → 60 against everything; lechatchila → כולו אסור. Cut fine → 60 against the whole radish; and per Rashba/Ran/Rama, lechatchila the whole radish is forbidden, bedieved only נטילה (Rama seif 1).
- ביטול ברוב and a different taste. Many pieces imported together nullify the knife's taste (lemon, salted fish — seif 4); and the turnip, of a different taste, nullifies the taste expelled from the knife (seif 5).
5. Mnemonic — the "חריף" memory aid
"ח-ר-י-ף" — after the charif, the heart of the siman
- חorfeih (its sharpness) + דוחקא דסכינא: the sharp food extracts the taste from the blade.
- רemoval at the cut spot: נטילת מקום (radish) up to the thickness of a finger.
- יesh omrim: even a knife that is not ben yomo but wiped is included.
- פeirud (separate / different taste): the turnip, of a different taste, nullifies the knife's taste.
The graded ladder of removal (most to least)
- נטילת מקום (thickness of a finger) → radish, beet, garlic, onion, horseradish — very charif
- קליפה (peeling) → intermediate level
- גרידה (scraping, < קליפה) → squash / cucumber, moist
- הדחה (rinsing) → turnip (different taste), or any sharp food tasted with no meat taste
6. The 4 classic pitfalls
❌ Pitfall 1 — Thinking a clean knife always permits: for an ordinary food, a clean meat knife would give only a faint, permitted taste (נ״ט בר נ״ט). But for a דבר חריף, the sharpness "awakens" that taste and extracts it like substance; it forbids even a non-ben-yomo knife (per Rashba / Sefer ha-Teroumot; for the Mehaber and the Mahara״m, only the קורט של חלתית is that sharp, while the others depend on ben yomo because of the שמנונית/fat — Taz s.k. 1, 3).
❌ Pitfall 2 — Confusing the two ladders: there is the ladder of removal (נטילה / קליפה / גרידה / הדחה by food) and the ladder of "how much is forbidden". Cut normally → נטילת מקום suffices. Cut דק דק → 60 against the whole radish. Lechatchila per Rashba/Rama → the whole radish forbidden, but bedieved only כדי נטילה. Do not mix the two.
❌ Pitfall 3 — Extending the stringency to the leaf and the doubt: all this applies when one cut the radish itself; but if one cut the leaf / greens on the radish, there is no concern. And in a case of doubt whether it was cut with a forbidden knife → one is lenient (לקולא); that is why one buys radishes that have cuts on the tail side (made with a hoe, מרא וחצינא). Where one finds only radishes cut with a knife → one buys them and permits by נטילת מקום.
❌ Pitfall 4 — Forgetting the ביטול and the different taste (seifim 4-5): lemon juice (מי לימוני״ש) and salted-fish pieces in barrels imported by non-Jews → permitted, because they are brought in great quantity together: what was forbidden is nullified (נתבטל) by the pieces cut afterward. Non-sharp foods (apples, dried turnips) → permitted like the lemon, without any stringency. And the turnip, of a different taste, nullifies the knife's taste; but one permits cutting the radish with it only once, not several times, unless one cuts turnip between each radish (seif 5).

7. Recap of the 5 seifim — one line each
| Seif | Topic | The essential |
|---|
| 1 | Radish / beet with a meat knife | צנון or סילקא (=תרדין) cut with a meat knife ben yomo or unwiped → forbidden with milk until נטילת מקום (thickness of a finger) or tasting with no meat taste (then הדחה). Yesh omrim: same for a non-ben-yomo but wiped knife. Neither removal nor tasting then cooked in milk → 60 against what the knife touched; a non-Jew's knife likewise. Rama: דק דק → 60 against the whole radish; Rashba/Ran: all forbidden (lechatchila the custom), bedieved נטילה; leaf → no concern; doubt → lenient (radishes cut with a hoe on the tail side). |
| 2 | The other sharp foods | Garlic (שומין), onions (בצלים), leeks (כרישין), horseradish (תמכא = קריי״ן) and other דברים חריפים, sour fruits (חמוצים), salted fish (דגים מלוחים) → same law as the radish. Rama: nevertheless one may eat the sharp preserves of non-Jews (ginger זנגביל…) since they have dedicated utensils or pluck them off (תולשין). |
| 3 | Spices crushed in a mortar | Spices (תבלין) crushed in a meat mortar (מדוכה) that is ben yomo → forbidden with milk. Yesh omrim: even non-ben-yomo (Rashba 449; see siman 95 end of seif 2 in the gloss). |
| 4 | Imported lemon / fish; ביטול | Lemon juice (מי לימוני״ש) and salted-fish pieces in barrels brought by non-Jews → permitted. Rama: because they are brought in great quantity together; what was forbidden (cut first) is nullified (נתבטל) by the rest, the knife's taste already nullified → all permitted. Hence the custom in some places to eat cabbage (כרוב / קומפש״ט) even sliced (others are stringent). Other non-sharp things (apples, dried turnips) → permitted like the lemon, without stringency. |
| 5 | Squash / turnip: גרידה and הדחה | Squash / cucumbers (קישואים) with a meat knife → permitted with milk by גרידה alone. Turnip (לפת) → even גרידה unnecessary, simple הדחה. More: a radish cut after the turnip → permitted by הדחה like the turnip, since its different taste nullifies the taste expelled from the knife. Rama: only a turnip of a different taste, not a vegetable / bread / other; and even with the turnip one permits cutting the radish only once, not several times, unless one cuts turnip between each. |
8. Final flashcard
| Question | Reflex answer | Source |
|---|
| Radish / beet with a ben-yomo meat knife? | Forbidden with milk → נטילת מקום (thickness of a finger) or tasting | Mehaber seif 1 |
| Why does a clean knife forbid? | חורפיה + דוחקא דסכינא: the charif extracts and diffuses the taste | Taz s.k. 3 |
| Garlic, onion, horseradish, sour fruits, salted fish? | Same law as the radish (charif) | Mehaber seif 2 |
| Cut very fine (דק דק) then cooked in milk? | 60 against the whole radish; lechatchila כולו אסור, bedieved נטילה | Rama seif 1 |
| Spices crushed in a meat mortar? | Ben yomo → forbidden; yesh omrim even non-ben-yomo | Mehaber seif 3 |
| Imported lemon / salted fish in quantity? | Permitted: ביטול ברוב; apples / dried turnips → permitted without stringency | Mehaber + Rama seif 4 |
| Squash / cucumber with a meat knife? | גרידה alone (scraping) | Mehaber seif 5 |
| Turnip with a meat knife? | הדחה suffices; and it nullifies the taste for a radish cut after it (once) | Mehaber + Rama seif 5 |
⚖ The reflex in 3 questions
- Which food? A דבר חריף (radish, beet, garlic, onion, horseradish, sour fruits, salted fish) → it extracts the knife's taste. Non-sharp (apple, turnip) → no concern.
- Which knife? Meat ben yomo or unwiped → forbidden; yesh omrim even non-ben-yomo wiped; a non-Jew's likewise.
- How much to remove? נטילת מקום (radish) > גרידה (squash) > הדחה (turnip); דק דק / lechatchila → everything; bedieved → only נטילה.

💡 Suggested next steps:
- Re-read Siman צ״ו in the original Choulhan Aroukh (Hebrew) with the Shach and the Taz
- Study the adjacent Simanim: 94 (the knife, נעיצה and הגעלה), 95 (נ״ט בר נ״ט, fish in a dairy dish), 103 (spices and the davar charif), 105 (diffusion / פעפוע and salting)
- Delve into Hullin 111b–112a (the davar charif and cutting with a knife) and the yesod of חורפיה דאגב דוחקא דסכינא
- Discuss personal cases with a Rav (radish, onion, horseradish cut at home, dedicated utensils) — the halacha le-ma'aseh is decided with a Rav
