3D Model Bolt Remover
Irwin bolt removers work great.
While trying to remove the blade from a neighbor's Honda lawn mower, I broke a 6 point 14mm socket wrench and rounded off the bolt head in the process. I went to the local home and garden store and picked up a set of Irwin bolt removers. I used a hammer to tap the 14mm remover onto the bolt head and then tried to remove the stuck bolt. I wasn't successful, but not because of the Irwin bolt remover, it didn't slip a bit. With a 18" breaker bar and a 12" cheater pipe, I was afraid that I was going to break off the bolt if I applied any more torque.
