Kevin,
That's pretty much how I got mine.  I was gunsmithing in a shop and the rep gave me one.  One tough knife.

I use a blade made for a Stanley utility knife.  It has a hook in it that's made for cutting carpet I believe.  Dull it up a little so it doesn't dig in.  It works great for removing fletching on any type of shaft material - wood aluminum or carbon.  It's cheap too.

With my Gold Tips, a utility knife (removable razor blades) works really well.  It doesn't work on CE.  They have different finishes.  CE is softer and the blade digs in very easily.
