I think my sledge is 8 pound and my Maul is 12 (it is part sledge part axe).. I have a straight wedge and a pointed wedge.. I have had some hunks of wood that flat did not want to split with the straight wedge so when that happens I did out Golden Boy (The pointed wedge has, or rather had, a gold finish)
I set the point on top of what looked like a good spot.. Gave it a couple of gentle taps to set it, oh, perhaps a quarter to half inch into the log, Stepped back and took a good "Manley" swing of the 8 pounder.. It went in much farther.
I took another wack and the point of the wedge was lodged in the dirt UNDER the freshly split log.
IF you are going to split a lot of wood.. Get a pointed wedge.
