Definition

  1. Mechateich is defined as cutting any item to a specific, desired size.[1]
  2. Mechateich applies to all materials. Nonetheless, Mechateich does not apply to foods.[2]
  3. In order to be chayav for Mechateich, one must perform the cutting in the usual manner, so if the cutting typically involves a tool, one will be patur if he performs the cutting with his hand.[3]

In the Mishkan

  1. In the Mishkan, Mechateich involved cutting animal skins to specific sizes in order to sew them into coverings for the structure of the Mishkan.[4]

Practical Examples

  1. One is chayav for tearing off a piece of aluminum foil, plastic wrap, or toilet paper from a long roll to a desired size.[5]
  2. One violates this melacha by sharpening a pencil[6] or by cutting one’s hair or nails to a desired length when using the appropriate tool.[7] Biting one’s nails or cutting them off by hand would only be a violation derabanan.[8]
  3. One may tear along the perforated lines of small packets of sugar, salt, ketchup, etc., even though one is cutting to a specific size, because the true purpose of the cutting is to create an opening, and one tears on these lines simply because it makes it easier to open the package. When one cuts along the perforations, he merely intends that the contents from the package should not spill out, not to cut the packet to a particular size.[9]
  4. Some say that it is permitted to separate yogurt containers that are attached together and it isn't considered Mechataich or Metaken. Nonetheless, one who separates them before Shabbat will be blessed.[10]
  5. Some Sephardic poskim allow ripping the toilet paper off of the perforated lines since one isn't cutting it to a specific size. It is best to rip it with one's elbow or another shinuy. Obviously one should prepare before Shabbat and not get into this situation.[11]
  6. Ripping not to a specific size can be permitted[12] or forbidden under Kore'ah.[13]
