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.
I think I saw it once in the back of a new print of keses hasofer. The sefer had a green cover and was medium thickness. I don't have the sefer anymore so I don't know who printed it...
ReplyDeleteIf you can get your hands on כתיבת סת"ם - אומנות הכתיבה ויסודותיה by R' Mordechai Mendelowitz, there's a whole section on writing lefty starting on p. 537 of volume 3. It includes diagrams of how to write the letters.
ReplyDeleteDo you know where this Sefer is available?
ReplyDeleteI bought my copy from the author, but he only had vols 1-2 left, I think. You can try virtualgeula.com, which is a used book finding service in Israel, and I think that the YU library has it as well, if you're in NY.
DeleteI could probably scan the relevant sections next week and e-mail them to you; email me at dovbergerATdovbergerDOTcom and I'll reply with it early next week. (Book's at home and scanner's at the office.)
