Look at the bottom and you will see a round plug that extends inside the handle. This holds the flint in. Cutting or drilling may cause this to fail.

To get it to fit inside the handle I had to cut past the plug. I replaced it with a short #4 screw. it's pretty solid so I'm not too concerned with that. Since I live in a desert I'm really not too worried about moisture degrading the flint either. It just sounds like a good idea to check every once in a while.
