Has anybody ever used a knife sharpening steel as a burnisher for scrapers?

I never have, all I use is the shank of an old Snap-on screw driver.

I’m not sure that’ll work the way we hope it would. All the knife steels I’ve used have longitudinal grooves, which would likely introduce an irregular edge to your scraper. I use a flat mill file to get the edge absolutely flat and square, then like Dallas, just use a smooth round bar to burnish. I bought a really nice burnisher bar from Ron Hock for like $15 or less. Before that, I just used a large screwdriver. Mine was a Klein, Dallas, but I’m generally a SnapOn guy too;)

I’m new at the whole scraper thing so I understand the principle but not sure on the burnishing part. So the burnisher does not have to have any sharpening qualities?

Thanks guys. Being an ex electrician, I’m a Klien guy too.

the burnisher just curls the sharp edge over to the side so that you can hold the scraper at the appropriate angle and take thin shavings, like the iron on a plane.

My steel is rough ‘cause it is designed to “refine” the edge of my knives. I have a burnisher that I made from a wrist pin from a motorcycle engine. It is hard-chromed, and extremely hard as well as polished. A steel won’t give ya the edge ya want. A polished, hardened edge will burnish and roll the edge needed. Some may use a shaft of a screwdriver. Better be a VERY high quality shaft. A true burnisher is best.

When I recently misplaced by burnishing steel, I subsituted a round pin punch as the burnisher. It worked awesome.

Some people have made a burnishing jig using the shank from a quarter inch router bit. Drill a hole in a block of wood to hold the angle of the bit. I use a good steel shank from a screw driver . (To tight to spend the monet on a real one !)

I use a knife steel. Works fine for me. Just make sure you hold it perpendicular to the scraper and don’t twist it. I don’t think you would anyhow, but if you twist your wrist, then what Al is saying holds true. I also add a drop of oil to mine. I use the mineral oil/diesel fuel mix I use on my oil stones, but any oil would work.
