Also, what different cutting materials do you find give you the most feedback about your cut.
For Example
Here is a cut today that I did an a Coke Can. I find coke cans give good feedback about cutting angle. If your angle is terrible then they tend to crumple before the blade rather than cut.
This particular cut was quite interesting. You can see that the Edge of the Top half of the cut is crisp and clean. The bottom half has actually been rolled over and created a lip on the can.
My Thoughts are that the blade alignment was angled a little high from my direction so the edge angled up to create a clean cut, and the bottom bevel because of the angle rolled the cut over on the bottom.
I find these cans cut perfectly crisp and clean leaving sharp edges with a good edge alignmnt (no matter what the entry angle is)
Any thoughts?
