It's a simple, but clever design: it works. The handle is just a pipe, welded to the base. The front tote is a truncated wooden cone, with a bolt running down the centre. The blade is a fairly hefty slab of metal, with a removable bolt with a wingnut holding it in place.
Maybe it was built just because it seemed like an interesting thing to do.
I gave it a quick try, and it seems good: flat sole, sturdy blade. Reasonably sharp (although it could use a sharpen).
I'm contem-plating flipping the blade so that it's bevel-up, then using this as a high-angle plane: I don't have one of **those** yet.
