Repair a detuning floyd rose bridge by sharpening the knife edges

In this video I recorded how I repaired a detuning floyd rose bridge in my guitar. The bridge was not keeping the guitar in tune - the difference between after pressing the tremolo arm down and after pulling it up was almost half a tone. I sharpened the edges at home using simple tools. If you want detailed instructions how to sharpen the knife edges, please read this article written by more experienced guys:
