Thanks Tom.
I've been using my own version of these for some years. The idea was given to me at least a decade ago by Philip Marcou, a planemaker in New Zealand. Philip described how you used offcuts of his D2 steel blades. I decided to try this with an offcut of an O1 blade. This blade is 3/16" thick, but 1/8" would work. Indeed, I have successfully used 2mm plate.
The scraper is sharpened by hollow grinding the edges. I use an 8" 180 grit CBN wheel ...
The result is magic! Think of it like a jack plane, which takes heavy cuts. Your card/cabinet scraper would bee the smoother.

There is tearout from the small high angle (60 degree) HNT Gordon smoother. That just shows how difficult this Jarrah is ...
The thick scraper sorts this out ...
Now, if you want to see the difference between a fine scraper and a fine sanded surface ...

The result from a cabinet scraper can be seen to the right ...
