Roebuck Fork, What you think?

While watching some youtube videos I came across to this new tool. Designed by Jodi Roebuck from Roebuck Farm, New Zealand. It is something between a broad fork and garden fork. I think it fills a niche. I designed my own broadfork couple of years ago, but now I need something that will help me as the soil gets better. Also broadforks are heavy and garden forks are too delicate. So, what you guys think? It seems something I might build it myself  (or anyone). There are so many tools that got lost as everything got mechanized, I can't keep myself from asking: Have you ever encountered a similar tool before? Probably they already began the production , as there are different models (in the pictures), 5 tine-7 tine?

I think that's pretty cool. Appears to be a scaled down broad fork. I bet it's probably similar to having different weight hammers, and having the right size for the job makes the job easier. I've been meaning to make myself a broad fork with the welder, maybe I'll make a small and a large.

bumping this old thread to say I love this design and would love to know if any one is really making this in US yet?

I prefer this handle design to the 2-handled broadfork for ergonomic reasons. As a mid '60's woman I had a dislocated bicep tendon brought on by use of a u-bar broadfork, and went back to using a conventional garden fork. A friend has a home-made broadfork with this type of handle and I can use it without aggravating this old injury.
