I was in the same boat. Go to KC Tool online and you can order Felo bits one at a time. I bought 3 T6s and 3 T8s for cheap. They are German made and have not stripped or failed. Probably as good as Wiha (I have a Wiha 1/4 inch driver). I rarely encounter T10s on knives. But that is a big enough screw head that stripping would likely not be an issue with a cheaper bit.Thanks, AW, but I'm just going to buy just bits, as I want two of each size......T6, T8, and T10, for sure.
Have you ever had to use T5, T7, or T9 on a folder? Thanks.
