I was concerned that the Accu-Burr, using two handles, prevented the process of drawing out steel prior to the formation of the burr/hook. Drawing out the steel creates a larger burr, and also work hardens the steel for a longer lasting edge.
I tested this out by drawing an edge with my usual burnisher, and then using the Accu-Burr to turn the hook. The resulting shaving was indeed larger as the edge bit more deeply into the wood. Consequently, I removed a handle so that one end of the Accu-Burr could be used to do duel duties.

This is a nice tool. Not essential, but it provides a consistent hook.
