We have this model ,this one can split to your size. The one in the vidio seems to split too smaller pieces of wood for me. I like them about 6-8in square. I use that size to start the wood burner Big machine for kindling
I can see this splitter working well in certain applications. It doesn't look like it would handle knotty or twisted grained wood very well, but straight grain red oak and the like would split well.
