Edge Knife

What is a "knife edge" bridge guitar?

My Guitar I want to bridge my guitar just to examine it, I am curious hwo to replace it in the future, because it gets old and rusty now ... but I have heard the term "knife edge", and watch the tension coils on the back of Trem and I can only assume the worst will happen when I try to take it away ... keep a sharp object pops out lol Trem and ruin my guitar when I try to by opening the Trem and take it away. I was curious, what is meant by a knife-edge. It is a steep part of the bridge "cuts" keep it in the timber or soemthing? I can spoil the guitar trying to take it away? and how am I supposed to do it ... Rotate the bridge in front (2 screws), try to get these tensions coils from the back? Here is a picture of my Wilkinson Tremolo http://arihoj.freehostia.com/images/rusty.png

It may be a good idea to read everything before you start. All you need some wire cutters and a little patience. Take your mouse and put it under the carpet behind the tremolo, because when cut the strings out of the tension springs make tremolo go back to dig up. Sponge may be squeezed back there.Next stems back to pop out while tremolo front.Pull tightly against the side of the springs, which are attached Trem is 1st, lift out of the loop side.The Trem is out now. set the guitar down on a towel or something soft like up.Now with Trem Trem lean slightly toward the neck and move back and up. It should pull straight up easily.Dont Touch 2 screws in it sat on, or 2 screws on the bottom (where the strings go) If the 2 screws are out, then put some tape to keep them from moving them, until you are ready to re-install the Trem. Replace rusted parts, and make sure that the character exactly, where they were before, and put them back in the same way you have them in my direction to turn off.Follow reinstallation Trem and you're ready to rock.
