NO. Never, NEVER do you pull out a blade on someone unless you intend to use it. Shit, If you were a dog I'd roll up a newspaper and smack you in the head. BAD IDEA.

No, if you intend on teaching him a lesson of any sort, you gotta give him a hands-on beating Ya know, show him who's the boss man for real...
