It would be kinda hard to sneak up on a werewolf if you had silver weapons on you.
Sure, pure silver is odorless, but silver does react with other things, and so a werewolf would be able to pick up the scent of silver compounds like silver sulfide.
Then again, if they can smell silver, and know it is dangerous to them, perhaps it would make them a little more wary about hunting someone who had silver on them?
@Zauberin Natural predator behaviour is to see your prey is armed and willing to throw down and going "understandable, have a nice day" so it'd track for a werewolf to do the same
Which makes for an awkward situation if you find some nice jewellery and your werewolf gf starts avoiding you when you come home
