There are several techniques to help with weak heels. A rolling x-stroke is best if it works, no special ‘tools’ needed. Sometimes you have to lift the toe up a little on the worse ones during that x-stroke. Sometimes a layer of tape seems to help the hone hit a weak heel, even thin Kapton.

Bill (BucaXXXX) used to put a short piece of electrical tape on the spine at the nose of Gold Dollars, effectively raising the toe, and creating a ‘hybrid’ edge, the tape had little effect on the angle at the heel then transitioned to a taped edge at the toe. But he was, at the time, prepping Gold Dollars to support noobs, so his goal was similar to Dovo’s goal, just get the razor out the door. Unlike Dovo’s razors though, Bill’s would shave!
