Subject: [Avodah] Real Chazon Ish Shiurim
See pp 10-11 from a booklet put out by R Hadar Yehudah Margolin, available
at www.dafyomi.co.il/lectures/reviis/kuntras-kzayis.pdf
What we call "Chazon Ish Shiurim" is a mistake. The measures given for the
Seder were not intended as iqar hadin, but included a safety margin beyond
the largest known shitah.
When it comes to Berakhos, you cannot make a berakhah for nothing. So when
the CI says that a kezayis for a berakhah is 1/3 of a contemporary egg, he
is pretty sure that is the actual halakhah.
R Chaim Kanievsky is later quoted as saying his uncle's kazayis comes to
30-33 cc (a/ka 30-33 ml, or 1-1.1 floz). R Moshe's Shiur, 31.2 cc (just a
shade over 1 floz), is in that range.
As I noticed comparing R Moshe Feinstein's shiurim and the Arukh haShulchan's, the Litvaks who put halachic weight to accepted practice are pretty consistent.
Shetir'u baTov!
Micha
