I received this question via email. I am not really a klaf expert, I was wondering if anyone could answer this question: Dear Rabbi Gutnick, I am writing to you because a good friend of mine has put the idea into my head that the klaf in my tefillin were not really tanned and therefore are not kosher. He referred me to Megilla 19a re diftera. From the research that I have done so far, it seems that the klaf that is used today is tanned only with a lime wash. On all of the tanning websites I’ve seen so far, they say that the lime doesn’t accomplish tanning but only the removal of the hair and some other pre-tanning effects. Would you be able to explain to me or refer me to a website that explains how the tanning process that is used today takes the hide out of the category of diftera? Thank you very much.
What " kabbalistic concept of not using metal as a writing instrument?!" Can you provide a source?
ReplyDeleteThe halacha is clearly stated in the Keses Hasofer that we write with any writing implement, "even with a metal pen."
The concept of not using metal for writing is well documented, and the source is Hilchos Gittin (see the Rema 125:4).
ReplyDeleteBut there are also those who say "al pi sod" not to use metal, because metal "shortens lives" and it says by the Mizbeach "Lo sonif aleyhem barzel" and this applies here as well.
There is a short but fundamental teshuvah by the Shevet Halevi on this whole concept which brings down all the opinions and the conclusion is not to use metal for writing, but better use a feather quill as per the accepted custom. See Shevet Halevi, chelek 2, siman 136.
Yosef's question is a fair one. I agree that it's somewhat ironic fixing tagei lamed which are supposed to be done "al pi hasod"( to mke the right higher than left) with a metal nibbed rapidograph that shouldn't really be used al pi hasod, because it shortens life.
