A shechita can be performed by a certified shochet, with a perfect knife, in the right place on the neck — and still fail, because of something that happens during the cut itself.
There are five such failures, and all five are traditions received at Sinai rather than derived from the text.
| Failure | What it is |
|---|---|
| Shehiyah | Pausing — lifting the hand mid-cut and then finishing |
| Drasah | Pressing — pushing the knife down instead of drawing it |
| Chaladah | Burrowing — a covered cut, the blade hidden |
| Hagramah | Cutting outside the permitted zone of the neck |
| Ikkur | Tearing — a siman torn or uprooted rather than cut |
A butcher who does not know these laws — it is forbidden to eat from his shechita.
Shehiyah, and a custom that erased a measurement
Shehiyah is where the shochet begins the cut, lifts his hand, and then completes it. Whether by accident or deliberately, under compulsion or by choice, the shechita is invalid.
The striking part is the history. The Gemara gave the pause a measured time limit — a pause shorter than that did not disqualify.
The custom in these lands erased the measurement entirely. Any pause at all, even the smallest, disqualifies — for a bird and an animal alike, even in a case of major financial loss or pressing need. And the sources are explicit that this is not to be changed.
That is a rare thing: a stringency adopted so firmly that it replaced the Talmudic standard outright. It is why the case law that follows deals with the smallest interruptions — grass caught in the windpipe, a bumped elbow, a startled shochet, a knife that turns out to be dull, a cut that began in the hide.
Drasah — the press and the chop
Shechita is a drawing cut. Drasah is what happens when it is not.
Laying the knife on the neck and pushing down — cutting the way one cuts a radish — is drasah. So, all the more, is striking the neck with the knife the way one strikes with a sword, severing the pipes with no drawing motion at all. Either way the shechita is invalid.
The rest, and how they are prevented
Chaladah is a burrowing cut, where the blade is covered rather than travelling openly through the neck. Hagramah is cutting outside the zone where shechita is valid. Ikkur is a pipe torn or pulled away rather than cut.
What is impressive is that the laws do not stop at defining them — they engineer against them:
- A minimum knife length, so that a proper drawing stroke is possible and pressing is never physically necessary.
- Grip rules, keeping fingers off the blade and preventing the pipes from being hidden under it.
- Warnings about wool, cloth and walls — anything that could cover the blade's path or obstruct it.
The prohibitions come with the conditions that make them avoidable, which is a notably practical way to write a law.
Two principles that govern all five
Every doubt in shechita is invalid. Not resolved leniently, not weighed — a doubt about whether one of the five occurred disqualifies.
The custom seals every loophole. Any of the five failures, in either minority of the cut, in either pipe, in an animal or a bird, invalidates the shechita.
Between them those two close the gaps that the individual definitions might otherwise leave, and they are why shechita is treated as an all-or-nothing act rather than something that can be partially right.
