I’ve just got through scraping a poor planing job and wondered if I was the only one left in the world that used cabinet scrapers? How do you create the burr? What are you using to burnish the hook?

No there are a lot of people using them. I use them. Here are a couple of sharpening aids I use for finish work

If I am using it for removal and don’t care as much about the a polished surface being left behind, I use Todd Clippingers method I found here on LumberJocks

I’ve been using card scrapers for about 40 years. I even make my own out of used saw blades, especially thin Japanese pull saws. I use a carbide rod burnisher for turning the burr.

This site has a plethora of information on card scraper.
Do a Google search for hundreds of articles and videos on this subject.

To create the burr, I use a fine mill file to flatten/square the edge. I burnish it with a home-made burnisher made from a diesel engine exhaust valve stem stuck into a wooden handle. The key to the burnisher is that it needs to be smooth and HARD. Use a wee bit of oil on the edge as you stroke the burnisher. (I lube it by rubbing alongside my nose or behind my ear, but wd-40 works, too). I usually lay the card flat and pull the burnisher toward the edge for the first couple strokes. This will draw any remaining burr back to the edge. I then clamp it into a vise edge up, and stroke it across about three to five times for each edge (softer the card, the less number of times), gradually increasing the angle.

I used to follow the initial edge flattening by mill file with standing the card on end on fine wet-dry paper (600 gr) to get a really smooth edge before burnishing. I have found this to be wasted effort for most use. It does produce a smoother edge for the last pre-finish cut especially on hard and burly woods, so I still do that for some projects.
