Was looking to get these for gym phones, and I saw the Kramer Mod. Do you have to have a drill in order to perform this mod? All I have really is an exacto knife.

The plastic is too thick and hard to use a knife...you'd probably end up slicing your fingers. If you try it BE CAREFUL. You could try burning the holes although I've never tried that, I used a drill.

Just get a drill, or a dremel. They are both VERY versatile tools.
