Kli sheMelachto l'Issur


Yesterday we explained that one of the four major categories of Muktzeh items is a kli shem'lachto l'issur, a tool which is used to perform tasks one may not perform on Shabbat. This includes pens, pencils and scissors, writing paper and pots and pans.

This category also includes items normally used for activities which are prohibited rabbinically on Shabbat, such as musical instruments. However, it only includes implements which are mostly used for prohibited purposes. Implements which are used equally for permitted and prohibited purposes have a separate status, as kli shemelachto l'issur ul'heter, and will be discussed on their own, Gd-willing.

(Shemirat Shabbat k'Hilchitah 20:5-6)

Have a great day,


  1. Good morning,
    I'm fascinated, if not puzzled, by the different applications of this to "clapping" on Shabbos. Can you offer some thoughts and sources here. Does clapping with the back of one's hand (if at all) offer a convincing and halachically acceptable alternative? Fair enough to just clap in the normal fashion?

    Thanks, Michael

  2. Hi Michael,

    I'm not sure I see the connection. What is the link between muktzeh and clapping?

  3. I suppose I was thinking about "clapping" as a form of "making music" and (with this e-mail addressing musical instruments) my mind wandered to clapping. This must be under the heading of a different malacha. Pardon the digression.
