Knee Knocker is a type of weapon that is shorter than a baseball bat, but long enough to swing at someone's knees. A Knee Knocker will be short enough to be portable, but long enough to reach at the knees of someone and possibly break their legs, if swung hard enough.

Often times, you'll see this being used as a self defense weapon and being at a fixed length. You can find telescoping ones and even some that can be specially designed to impact with the most amount of energy.
This person came up to me and I decided to use my Knee Knocker to knock their knees out.
