No, you missed it- the wood handle cant split- because it already is ‘split’ from the factory. It is two different pieces of wood.
I did this using the same one for years at a time. The front of the blade gets chipped and broken until the thing is no longer useable after about 100 engines. I use it to remove valve covers, pan, timing cover, basically everything in a tear down. Yes usually a ball peen hammer. I consider them a wear item like grinder disks. It’s like $1.50 tool, well probably $2.50 nowdays. But if you can find one in 99 cent store, get it instead. If you use it to remove one valve cover or one oil pan, it paid for itself.
