Hi, I am having trouble splitting pine with my Fiskars x27. A neighbor let me have rounds/logs, 18" H x 14" W from a pine tree that blew over in a storm last winter. When I go to split them with my Fiskars x27 maul/splitting axe, it just sinks into the log and does not split. It is really hard to pull out the Fiskars! I have had the logs stacked off the ground since August exposed to lots of wind and sun. Is the problem that the wood is still too wet? Will waiting until winter help when the wood is frozen? How can I get these pine rounds/logs split? Thanks.
