What do you do: use them like a yawara stick? Maybe strike at an opponent's eyes? Nerve centers?
In the Modesty Blaise fiction series, Modesty had a stick that looked like a handle on her purse, but snapped off to become a yawara stick. I think she also had a lipstick that fired tear gas. She used guns, but had additional means of defense, as well as being excellent at unarmed combat. The books are superb; the TV series and movies not so good. The comics are my favorite, ever, but were only seen in one US newspaper, as it was not considered family fare.
My pens are Parkers and by Cross. I bet they'd do some damage, though, in the right hands. I think Parker's stainless T-Ball Jotter is one of the best pen values ever. I have more expensive Parkers, sterling silver, but have a few Jotters around my desk and in a briefcase.
