The “ogre club” looks very much like a hammer used with a froe to split cedar shakes/shake blocks. Back in the 1970s our froe hammers were round blocks of aluminum attached to about 1.25” steel cable length. Your club looks like something that might have been used back in the 50s or earlier. I could see the spike at the end would be handy to stick it into a log so it doesn’t roll off into the slash while moving your cedar blocks around.
