We love the Park Tool SG-7. 2 Saw Guide. It accurately guides a saw blade making cutting fork steerer tubes, aero seat posts, and integrated seat tubes a breeze. It's recently released the SGI-7 insert for the guide that facilitates accurate cutting a 30-degree angle on the ends of either alloy or carbon bars needed to properly install WTB PadLoc grips. The right tool, the right job.
