Weapons are not clothing or adornment — they're burdens. The Rambam cites Isaiah: "they shall beat swords into plowshares." Weapons represent the opposite of Shabbat's peace.
Question 2
A woman wants to wear a ring with a seal on Shabbat. Can she?
A ring with a seal is classified as a man's implement. A woman wearing it isn't adorning herself — she's carrying. A ring without a seal is the reverse: women's jewelry, carrying for men.
Question 3
Why are certain women's jewelry items forbidden to wear outside on Shabbat?
The Sages' concern: a woman might remove attractive jewelry to show a friend in the public domain, then carry it back. The prohibition prevents accidental carrying.
Question 4
A tailor goes out on Shabbat with a needle stuck in his shirt. Is he liable?
A needle in a tailor's clothing is a tool of his trade, not an item of clothing. He's carrying it, even though it's attached to his garment.
Question 5
What should a tailor do on Friday afternoon before Shabbat?
Practical advice: check your clothes before Shabbat. Professionals who routinely carry tools in their clothing must verify they're clean before sunset.
