The cost of any type of customization such as checkering will vary depending on exactly what you want done. For example, I wanted to use the Native w/o the pocket clip so I had both sides checkered. If you plan on leaving the clip in place, you might want to checker the other side only. I suggest you call CheckerMarx, explain what you might want done, and ask for an estimate.
