I own a Lansky turn box and i really like it because it gets my blades arm hair shaving sharp for a very low price. I don't know how your serrations are, but it will probably fit in the large part of most serations. If you have a serrated blade that goes from 1 large part to 3 small ones and then 1 large part again it will probably not fit in the small cutting parts. The size of the rods is comparable to an M8 size bolt.
