Check out the fork in this Edible Acres
video:
Not available from Reble Tools at this time.
5 tines, very broad, almost the width of a broadfork but with a central handle.
These forks push the difference between
hay and garden forks further.
I think I could make a decent no weld fork by cutting, drilling and bolting together bedframe.
The metal is very tough, and the L cross section makes it even stronger.
The hardest part would be making a handle that is strong
enough but also grippable.
