I recently picked up a cheap set of 6" T handle torx wrenches. I managed to twist the shaft of the T10 wrench on the first use so I decided to shorten them by 2" to hopefully get less flex. I took my time and marked each of them with strips of painters tape to mark the cut, but after cutting down the 3rd one, I realized that only the tip was formed into the torx bit and I had just created hex wrenches. I never cease to amaze myself.
