To a point I just like my toys. For personal use I get through about 18m3 per winter so not a massive amount. When I get surplus I sell it so I can get through up to maybe 50m3 per year. I still split all my wood with an axe - a nice Gransfors maul. I want a screw splitter too but if I keep buying these little affordable treats I'll never save up enough to buy a mog!
It's got a chain that hangs down on the far side of the blade so you know where to cut. I'm sure that could be replaced with a stop bar if needed, but a chain is probably going to be a good enough guide?
