Thrust only, 1-2 dmg, 4 AP's, 50% deterioration rate, craftable, can be bought from medical professionals, or stolen (automatic success, but 0 xp). Base price: 3 caps for 5 pens. "Mostly good for starting a fight, not so much for ending it."
And based on a true story.
EDIT; when I wrote this I was pretty high on tramadol, but looking at it sober..... maybe it's not all a bad idea..... mostly for the lol factor.
