When I bought this nine piece TORX key set I thought it was absolutely fantastic – looks lovely, easy to see which size key is which, lots of size options, feels great in the hand.
Then I started using it. The tool storage clip gets in the way, and you often have to move two other keys to get the key you want out of it. The short arms are too short, and it’s difficult to get traction if you have long bolts you need to tighten. More generally, the keys are too narrow to get a good grip.
