A Comparison of Deburring Techniques

This is just a quick comparison of three different deburring techniques: Pulling the apex though a piece of wood, pulling the apex through a cork, and shearing off the burr using high angle passes. If anyone watching this has had any repeatable success with pulling the apex though a stiff material to deburr, could you please leave a comment and explain the techniques, because I found I had no success whatsoever with any pull-through deburring technique.
