Never Lost Drill Bit Key Again

I am using this very old drill (still working perfectly fine). Key for attaching bits was fixed to the drill cord by little rope and it become weak and cutted off by aging. I put 2 zip tie, 1 around drill cord, not too tight so it can move around and bot to big so it cant go over plug ob the end of the electric cord. Than I another to the bit key to fix it with first 1. Zip tie is strong and durable and I think this will last longer than drill :) .
