That's some good clean cuttin!
I got one for ya. Take an empty cola can and set it on the edge of a table or chunk of firewood. . Slice diagonally though it cutting it clean. I have a picture of me right as I am about to swing. The knife should clear the table edge and the can should be in two peices.
I can do this most of the time, but the edge has to be on the thin side to do well. Plus it takes a slice, not a chop.
