Shagbark hickory is very heavy and is a pain in the neck to split. This has been a public service announcement. We now return to our regularly scheduled programming. Seriously, though, wow, that is some tough wood. The rounds from the upper parts of the tree were incredibly stringy and knotty. As I moved into the rounds form the main truck and closer to the base, they obviously got much bigger and heavier but were straight grained and popped apart relatively easily. It is stunning how much a medium-sized split weighs. I ought to do a test of weighing a particular piece now and two years from now when it will get burned.
