I did this ripping a 1/8" strip off a 3/4x3/4x6" piece of wood on a table saw. I didn't cut myself on the blade, the larger piece caught an fired back against my thumb that was pushing it along. Just a simple square corner lifted about 1/2x3/4" of skin, all the layers I think.

I know the smarter way to do things, I just do what is fastest and easiest first.
