I mean it's a wrench, you can use a regular one but it doesn't angle out so your hand might get caught on the drivetrain and you don't want to bend a wrench just to tighten your pedals. It was a good purchase, I bring it with me wherever I go just in case because I also use it as an ordinary wrench too.
Works as it should, very well made.
