MISHNA BERURAH YOMI MISHNA BERURAH DIRSHU CHELEK 2 OCTOBER 26

S"A SIMAN 180 4 MISHNA BERURA SIF KATAN 9 there are /authorities/ who are stringent where there are a lot of pieces involved which are collectively /as large/ as an olive. SIF 5 MISHNA BERURA SIF KATAN 11 In the B.Y. two reasons /are given for this/. One /reason/ is that iron 8 shortens the life of man and /, therefore,/ it is not right that it should be lying on the table, since /a table/ is compared to an altar, which /serves to/ extend the life of man. That is why it is stated 9 /with respect to the stones from which the altar is built/: “You shall not raise iron over them.” Consequently, after one has finished eating and wishes to say Grace after Meals he should cover the knife. The second reason, /given/ in the name of Rabbeinu Simchah, is /that it is/ because once when someone reached the blessing Boneih Yerushalayim 10 (Who builds Jerusalem) he remembered the destruction of the Beys Ha-Mikdash/ (the Holy Temple) and /in his distress/ stuck a knife in his stomach. Consequently, it became customary to remove /the knife/ while Grace /after Meals are being said/.
