I've had tamper torx for years. I don't think I've ever used them on the matching fasteners. Although, I have been tempted to take out the screws on the bathrooms stalls as a joke. I did pick up a set of medium deep, 3/8" drive standard sockets. Those will come in handy on more than one occasion. I also picked up a 2' long, 1/2" drive ratchet for the race car. Time to find and engraver/etcher to have the team name put on the thing. That way, if it gets stolen, the thieves will know who they stole it from!
