Shabbos 6:4-5

Shabbos 6:4

A man may not go out on Shabbos with a sword, a bow, a shield, a mace, or a spear; if he did go out with one of these things, he would be required to bring a sin offering. Rabbi Eliezer suggests that weapons should be considered ornaments for a man (based on Psalms 45:4) but the Sages consider weapons disgraceful since Isaiah 2:4 says that ultimately swords will be beaten into plows and spears will be beaten into pruning hooks (showing that they are not inherently desirable). A garter used to hold up leg protection is not susceptible to ritual uncleanliness (because it is subordinate to a garment and not a garment in its own right) and a woman may wear it out on Shabbos (because she is unlikely to remove it). If they have chains on them (used to ensure small footsteps), they are susceptible to ritual uncleanliness (because they serve a purpose in and of themselves) and a woman may not wear them out on Shabbos (because she might remove the chains in the public domain).

Shabbos 6:5

A woman may go out on Shabbos with strands of hair (to tie up her own hair) whether they are from her, another woman or an animal. She may go out with a headband or a headdress when they are sewn to her hat. She may wear a cap or a wig into the courtyard (but not into the public domain). She may go out with cotton in her ear, a pad for cushioning in her shoe, a sanitary napkin, pepper (in her mouth as a breath freshener), salt (in her mouth to treat a toothache), or with anything else she might put in her mouth as long as it is not put there initially on Shabbos. If it fell from her mouth on Shabbos, she may not replace it. Rebbi permits her to go out with a false tooth or a gold dental crown but the Sages do not allow this.
