I recently chopped the head off a frozen beaver that the coyotes got to first. They had already destroyed the hide, but I am cleaning and keeping the skull for science. The SDFK experienced some minor edge damage. Some rolling, dents, maybe 10-15 thou deep. More than I expected, but still good considering frozen bones are hard. It would have been quite a bit more difficult with the BFK, and I dont have my SC yet to compare. Long story short, SDFK is awesome and will do it, whatever it is.
