A man may not go out neither with a sword, nor with a bow, nor with a shield, nor with a buckler, nor with a spear. And if he went out, he is liable for a sin offering. R’ Eliezer says: They are adornments for him. But the Sages say: They are nothing but a disgrace, as it is said, And they shall beat their swords into plowshares and their spears into pruning hooks; one nation shall not lift up a sword against another nation, neither shall they learn war anymore (Isaiah 2:4). A garter is not susceptible to tumah-contamination, and we may go out with it on the Sabbath; ankle chains are susceptible to tumah-contamination, and they may not go out with them on the Sabbath.
