We are beginning siman 3. The Chayei Adam writes that cutting letters from a piece of hide or leather is included in the issur deoraysa of koseiv. However, rosheim, which is using a blunt instrument to make impressions in leather (without cutting it), is not chayav. The reason one is not chayav is because nothing […]

  We have finished siman 1, and need to clarify one point. The Chayei Adam wrote that reshima is chayav. The Gemara explains that reshima refers to making a symbol as a signature instead of writing one’s name. For example, Rav would make a picture of a fish instead of signing his name. This symbol […]

  We are continuing in an introduction to Klal 37, the melacha of koseiv. In the previous shiur, we learned that combining letters to create words is not koseiv, because the melacha of koseiv is specifically creating the letters. However, there is a way to create letters which would mistakenly be excluded based on that […]

    We are beginning Klal 37, which discusses the melacha of koseiv, writing. The source for this melacha is that the kerashim (the wooden beams) outside of the Mishkan would be labeled in order to identify that they were put back in the same place every time they were moved. This was done to […]

  We are beginning siman 3. The Chayei Adam writes, based on the Shulchan Aruch, that the concept of mechateich does not apply to food. Thus, if a person wants to cut a piece of cake to a certain size, or divide a pie into exact slices, the melacha of mechateich does not apply. The […]

  We are beginning siman 2, where the Chayei Adam gives the shiur necessary to be chayav for mechateich.   The Chayei Adam writes that one is chayav for mechateich if they cut off a piece of leather from a hide that is large enough to cover a kameiah (amulet). The Chayei Adam clarifies that, […]

We are beginning Klal 36, which discusses the melacha of mechateich. One of steps to processing leather was cutting it to a specific size in order to use it.
