Has anyone made the kerfing plane described by Tim Fidgen in the Unplugged Workshop

Has anyone made this plane (really a saw)?

There are some good videos on You Tube showing how to make one and use it.

I was thinking of making one but can't seem to find a suitable blade in Australia. You can buy a kit which includes the parts for a Frame Saw as well from Bad Axe Saws in the US but the price is a bit high, and I only want the blade.

If anyone has made the plane, where did you find a suitable blade?

Thanks
