The closest you can come to this is finding the appropriate trap ingredient and then using a grenade with it.
I was told this too, and it's bullshit. Not only that, it's so fucking obscure the only people who could use it are people who haven't already found the requisite avg 21 (minimum) dagger/sword/mace through PK. Sure you could stack vulns (as I'm assuming the other part of this dumb shit rumor is that the attack type of the given weapon doesn't change) but until a log comes up I wouldn't put stock in this.
