Assassination Trivia

[brtmchl]

I'm sorry, This is my first trivia question I have put out. It is a lot more difficult than I expected. Please bear with me I should clarify.

LincolnMan and asobobbingfilm are both correct that the term means manipulative. But there was a device created in the 1840's that I believe Asa was refering to while also calling her manipulative. It goes along with him calling her a man trap. It was called a Sockdolger. It was also known by a different name. What was this device. And what other name did it go by?

Sorry, Damn Rookies. I'll work on my trivia asking skills
